Class NodeImpl

    java.lang.Object
      weblogic.apache.xerces.dom.NodeImpl

All Implemented Interfaces:
  Cloneable, EventTarget, Node, NodeList, Serializable

Direct Known Subclasses:
  AttrImpl, ChildNode, NotationImpl

Deprecated. please use JDK supplied XML parsers and transformers

public abstract class NodeImpl
extends Object
implements Node, NodeList, EventTarget, Cloneable, Serializable

NodeImpl provides the basic structure of a DOM tree. It is never used directly, but instead is subclassed to add type and data information, and additional methods, appropriate to each node of the tree. Only its subclasses should be instantiated -- and those, with the exception of Document itself, only through a specific Document's factory methods.

The Node interface provides shared behaviors such as siblings and children, both for consistancy and so that the most common tree operations may be performed without constantly having to downcast to specific node types. When there is no obvious mapping for one of these queries, it will respond with null. Note that the default behavior is that children are forbidden. To permit them, the subclass ParentNode overrides several methods.

NodeImpl also implements NodeList, so it can return itself in response to the getChildNodes() query. This eliminiates the need for a separate ChildNodeList object. Note that this is an IMPLEMENTATION DETAIL; applications should _never_ assume that this identity exists.

All nodes in a single document must originate in that document. (Note that this is much tighter than "must be same implementation") Nodes are all aware of their ownerDocument, and attempts to mismatch will throw WRONG_DOCUMENT_ERR.

However, to save memory not all nodes always have a direct reference to their ownerDocument. When a node is owned by another node it relies on its owner to store its ownerDocument. Parent nodes always store it though, so there is never more than one level of indirection. And when a node doesn't have an owner, ownerNode refers to its ownerDocument.

This class doesn't directly support mutation events, however, it still implements the EventTarget interface and forward all related calls to the document so that the document class do so.

### changed

    protected void changed()

  Deprecated.
  Denotes that this node has changed.

### changes

    protected int changes()

  Deprecated.
  Returns the number of changes to this node.

### cloneNode

    public Node cloneNode(boolean deep)

  Deprecated.
  Returns a duplicate of a given node. You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.

  Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior.

  Specified by:
    `cloneNode` in interface `Node`
  See Also:
    `

    Example: Cloning a Text node will copy both the node and the text it contains.

    Example: Cloning something that has children -- Element or Attr, for example -- will _not_ clone those children unless a "deep clone" has been requested. A shallow clone of an Attr node will yield an empty Attr of the same name.

    NOTE: Clones will always be read/write, even if the node being cloned is read-only, to permit applications using only the DOM API to obtain editable copies of locked portions of the tree.

    `

### compareTreePosition

    public short compareTreePosition(Node other)

  Deprecated.
  Compares a node with this node with regard to their position in the tree and according to the document order. This order can be extended by module that define additional types of nodes.

  Parameters:

  Returns:
    Returns how the given node is positioned relatively to this node.
  Since:
    DOM Level 3

  Deprecated.
  Specified by:
    `dispatchEvent` in interface `EventTarget`

### getAttributes

    public NamedNodeMap getAttributes()

  Specified by:
    `getAttributes` in interface `Node`
  See Also:
    `ElementImpl`

### getBaseURI

    public String getBaseURI()

  Deprecated.
  The absolute base URI of this node or `null` if undefined. This value is computed according to . However, when the `Document` supports the feature "HTML" , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the `documentURI` attribute from the `Document` interface otherwise.
  When the node is an `Element`, a `Document` or a a `ProcessingInstruction`, this attribute represents the properties [base URI] defined in . When the node is a `Notation`, an `Entity`, or an `EntityReference`, this attribute represents the properties [declaration base URI] in the . How will this be affected by resolution of relative namespace URIs issue?It's not.Should this only be on Document, Element, ProcessingInstruction, Entity, and Notation nodes, according to the infoset? If not, what is it equal to on other nodes? Null? An empty string? I think it should be the parent's.No.Should this be read-only and computed or and actual read-write attribute?Read-only and computed (F2F 19 Jun 2000 and teleconference 30 May 2001).If the base HTML element is not yet attached to a document, does the insert change the Document.baseURI? Yes. (F2F 26 Sep 2001)

  Specified by:
    `getBaseURI` in interface `Node`
  Since:
    DOM Level 3

### getChildNodes

    public NodeList getChildNodes()

  Deprecated.
  Obtain a NodeList enumerating all children of this node. If there are none, an (initially) empty NodeList is returned.

  NodeLists are "live"; as children are added/removed the NodeList will immediately reflect those changes. Also, the NodeList refers to the actual nodes, so changes to those nodes made via the DOM tree will be reflected in the NodeList and vice versa.

  In this implementation, Nodes implement the NodeList interface and provide their own getChildNodes() support. Other DOMs may solve this differently.

  Specified by:
    `getChildNodes` in interface `Node`

### getFirstChild

    public Node getFirstChild()

  Deprecated.
  The first child of this Node, or null if none.

  By default we do not have any children, ParentNode overrides this.

    public Node getInterface(String feature)

  Deprecated.
  This method makes available a `Node`'s specialized interface.

  Parameters:
    `feature` - The name of the feature requested (case-insensitive).
  Returns:
    Returns an alternate `Node` which implements the specialized APIs of the specified feature, if any, or `null` if there is no alternate `Node` which implements interfaces associated with that feature. Any alternate `Node` returned by this method must delegate to the primary core `Node` and not return results inconsistent with the primary core `Node` such as `key`, `attributes`, `childNodes`, etc.
  Since:
    DOM Level 3

### getLastChild

    public Node getLastChild()

  Deprecated.
  The first child of this Node, or null if none.

  See Also:
    `ParentNode`

### getLength

    `getLength` in interface `NodeList`
  Returns:
    int
  See Also:
    `ParentNode`

### getLocalName

    public String getLocalName()

  Deprecated.
  Introduced in DOM Level 2.

  Returns the local part of the qualified name of this node. For nodes created with a DOM Level 1 method, such as createElement from the Document interface, and for nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is the same as the nodeName attribute.

    WD-DOM-Level-2-19990923
  See Also:
    `AttrNSImpl`, `ElementNSImpl`

### getNamespaceURI

    public String getNamespaceURI()

  Deprecated.
  Introduced in DOM Level 2.

  The namespace URI of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE, this is always null and setting it has no effect.

  This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

  For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

  Specified by:
    `getNamespaceURI` in interface `Node`
  Since:
    WD-DOM-Level-2-19990923

  Obtain the DOM-tree parent of this node, or null if it is not currently active in the DOM tree (perhaps because it has just been created or removed). Note that Document, DocumentFragment, and Attribute will never have parents.

  Specified by:
    `getParentNode` in interface `Node`

### getPrefix

    public String getPrefix()

  Deprecated.
  Introduced in DOM Level 2.

  The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

### getTextContent

    public String getTextContent()
                          throws DOMException

  Deprecated.
  This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single `Text` node containing the string this attribute is set to. On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
  The string returned is made of the text content of this node depending on its type, as defined below:

  Node type | Content
  --- | ---
  ELEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE | concatenation of the `textContent` attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes
  ATTRIBUTE_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE | `nodeValue`
  DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE | null

  Specified by:
    `getTextContent` in interface `Node`
  Throws:
    `DOMException` - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
    `DOMException` - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a `DOMString` variable on the implementation platform.
  Since:
    DOM Level 3

  Returns:
    Returns the `DOMObject` associated to the given key on this node, or `null` if there was none.
  Since:
    DOM Level 3

### insertBefore

    public Node insertBefore(Node newChild,
                             Node refChild)
                      throws DOMException

  Deprecated.
  Move one or more node(s) to our list of children. Note that this implicitly removes them from their previous parent.

  By default we do not accept any children, ParentNode overrides this.

  Specified by:
    `insertBefore` in interface `Node`
  Parameters:
    `newChild` - The Node to be moved to our subtree. As a convenience feature, inserting a DocumentNode will instead insert all its children.
    `refChild` - Current child which newChild should be placed immediately before. If refChild is null, the insertion occurs after all existing Nodes, like appendChild().
  Throws:
    `DOMException(HIERARCHY_REQUEST_ERR)` - if newChild is of a type that shouldn't be a child of this node, or if newChild is an ancestor of this node.
    `DOMException(WRONG_DOCUMENT_ERR)` - if newChild has a different owner document than we do.
    `DOMException(NOT_FOUND_ERR)` - if refChild is not a child of this node.

### isEqualNode

    public boolean isEqualNode(Node arg)

  Deprecated.
  Tests whether two nodes are equal.
  This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with `Node.isSameNode`. All nodes that are the same will also be equal, though the reverse may not be true.
  Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: `nodeName`, `localName`, `namespaceURI`, `prefix`, `nodeValue` , `baseURI`. This is: they are both `null`, or they have the same length and are character for character identical. The `attributes` `NamedNodeMaps` are equal. This is: they are both `null`, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.The `childNodes` `NodeLists` are equal. This is: they are both `null`, or they have the same length and contain equal nodes at the same index. This is true for `Attr` nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
  For two `DocumentType` nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: `publicId`, `systemId`, `internalSubset`.The `entities` `NamedNodeMaps` are equal.The `notations` `NamedNodeMaps` are equal.
  On the other hand, the following do not affect equality: the `ownerDocument` attribute, the `specified` attribute for `Attr` nodes, the `isWhitespaceInElementContent` attribute for `Text` nodes, as well as any user data or event listeners registered on the nodes.

  Specified by:
    `isEqualNode` in interface `Node`
  Parameters:
    `arg` - The node to compare equality with.
  Returns:
    If the nodes, and possibly subtrees are equal, `true` otherwise `false`.
  Since:
    DOM Level 3

### isSameNode

    public boolean isSameNode(Node other)

  Deprecated.
  Returns whether this node is the same node as the given one.
  This method provides a way to determine whether two `Node` references returned by the implementation reference the same object. When two `Node` references are references to the same object, even if through a proxy, the references may be used completely interchangably, such that all attributes have the same values and calling the same DOM method on either reference always has exactly the same effect.

  Specified by:
    `isSameNode` in interface `Node`
  Parameters:
    `other` - The node to test against.
  Returns:
    Returns `true` if the nodes are the same, `false` otherwise.
  Since:
    DOM Level 3

### isSupported

    public boolean isSupported(String feature,
                               String version)

  Deprecated.
  Introduced in DOM Level 2.

  Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

  Specified by:
    `isSupported` in interface `Node`
  Parameters:
    `feature` - The package name of the feature to test. This is the same name as what can be passed to the method hasFeature on DOMImplementation.
    `version` - This is the version number of the package name to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true.
  Returns:
    boolean Returns true if this node defines a subtree within which the specified feature is supported, false otherwise.

### item

    public Node item(int index)

  Deprecated.
  NodeList method: Return the Nth immediate child of this node, or null if the index is out of bounds.

  By default we do not have any children, ParentNode overrides this.

  Specified by:
    `item` in interface `NodeList`
  Returns:
    org.w3c.dom.Node

    `ParentNode`

### lookupNamespacePrefix

    public String lookupNamespacePrefix(String namespaceURI,
                                        boolean useDefault)

  Deprecated.
  DOM Level 3 - Experimental: Look up the prefix associated to the given namespace URI, starting from this node.

  Parameters:
    `namespaceURI` -
    `useDefault` -
  Returns:

### lookupNamespaceURI

    public String lookupNamespaceURI(String specifiedPrefix)

  Deprecated.
  DOM Level 3 - Experimental: Look up the namespace URI associated to the given prefix, starting from this node. Use lookupNamespaceURI(null) to lookup the default namespace

  Specified by:
    `lookupNamespaceURI` in interface `Node`
  Returns:
  Since:
    DOM Level 3

### needsSyncChildren

    public final void needsSyncChildren(boolean value)

  Deprecated.

### normalize

    public void normalize()

  Deprecated.
  Puts all `Text` nodes in the full depth of the sub-tree underneath this `Node`, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates `Text` nodes, i.e., there are no adjacent `Text` nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains `CDATASections`, the normalize operation alone may not be sufficient, since XPointers do not differentiate between `Text` nodes and `CDATASection` nodes.

  Note that this implementation simply calls normalize() on this Node's children. It is up to implementors or Node to override normalize() to take action.

  Specified by:
    `normalize` in interface `Node`

### removeChild

    public Node removeChild(Node oldChild)
                     throws DOMException

  Deprecated.
  Remove a child from this Node. The removed child's subtree remains intact so it may be re-inserted elsewhere.

  By default we do not have any children, ParentNode overrides this.

  Specified by:
    `removeChild` in interface `Node`
  Returns:
    oldChild, in its new state (removed).
  Throws:
    `DOMException(NOT_FOUND_ERR)` - if oldChild is not a child of this node.
    `DOMException(NO_MODIFICATION_ALLOWED_ERR)` - if this node is read-only.
    `DOMException`
  See Also:
    `ParentNode`

### removeEventListener

    public void removeEventListener(String type,
                                    EventListener listener,
                                    boolean useCapture)

  Deprecated.
  Specified by:
    `removeEventListener` in interface `EventTarget`

### replaceChild

    public Node replaceChild(Node newChild,
                             Node oldChild)
                      throws DOMException

  Deprecated.
  Make newChild occupy the location that oldChild used to have. Note that newChild will first be removed from its previous parent, if any. Equivalent to inserting newChild before oldChild, then removing oldChild.

  By default we do not have any children, ParentNode overrides this.

  Specified by:
    `replaceChild` in interface `Node`
  Throws:
    `DOMException(HIERARCHY_REQUEST_ERR)` - if newChild is of a type that shouldn't be a child of this node, or if newChild is one of our ancestors.
    `DOMException(WRONG_DOCUMENT_ERR)` - if newChild has a different owner document than we do.
    `DOMException(NOT_FOUND_ERR)` - if oldChild is not a child of this node.
    `DOMException(NO_MODIFICATION_ALLOWED_ERR)` - if this node is read-only.
    `DOMException`

    `ParentNode`

### setNodeValue

    public void setNodeValue(String x)
                      throws DOMException

  Deprecated.
  Sets the node value.

  Specified by:
    `setNodeValue` in interface `Node`
  Throws:
    `DOMException(NO_MODIFICATION_ALLOWED_ERR)`
    `DOMException`

### setPrefix

    public void setPrefix(String prefix)
                   throws DOMException

  Deprecated.
  Introduced in DOM Level 2.

  The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

  For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

  Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.

  Specified by:
    `setPrefix` in interface `Node`
  Throws:
    `INVALID_CHARACTER_ERR` - Raised if the specified prefix contains an invalid character.
    `DOMException`
  Since:
    WD-DOM-Level-2-19990923
  See Also:
    `AttrNSImpl`, `ElementNSImpl`

### setReadOnly

    public void setReadOnly(boolean readOnly,
                            boolean deep)

  Deprecated.
  NON-DOM: PR-DOM-Level-1-19980818 mentions readonly nodes in conjunction with Entities, but provides no API to support this.

  Most DOM users should not touch this method. Its anticpated use is during construction of EntityRefernces, where it will be used to lock the contents replicated from Entity so they can't be casually altered. It _could_ be published as a DOM extension, if desired.

  Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior.

  Parameters:
    `readOnly` - True or false as desired.
    `deep` - If true, children are also toggled. Note that this will not change the state of an EntityReference or its children, which are always read-only.
  See Also:
    `ParentNode`

### setTextContent

    public void setTextContent(String textContent)
                        throws DOMException

  Deprecated.
  This attribute returns the text content of this node and its descendants. When it is defined to be null, setting it has no effect. When set, any possible children this node may have are removed and replaced by a single `Text` node containing the string this attribute is set to. On getting, no serialization is performed, the returned string does not contain any markup. No whitespace normalization is performed, the returned string does not contain the element content whitespaces . Similarly, on setting, no parsing is performed either, the input string is taken as pure textual content.
  The string returned is made of the text content of this node depending on its type, as defined below:

  Node type | Content
  --- | ---
  ELEMENT_NODE, ENTITY_NODE, ENTITY_REFERENCE_NODE, DOCUMENT_FRAGMENT_NODE | concatenation of the `textContent` attribute value of every child node, excluding COMMENT_NODE and PROCESSING_INSTRUCTION_NODE nodes
  ATTRIBUTE_NODE, TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE, PROCESSING_INSTRUCTION_NODE | `nodeValue`
  DOCUMENT_NODE, DOCUMENT_TYPE_NODE, NOTATION_NODE | null

  Specified by:
    `setTextContent` in interface `Node`
  Throws:
    `DOMException` - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
    `DOMException` - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a `DOMString` variable on the implementation platform.
  Since:
    DOM Level 3

### setUserData

    public void setUserData(Object data)

  Deprecated.
  NON-DOM: As an alternative to subclassing the DOM, this implementation has been extended with the ability to attach an object to each node. (If you need multiple objects, you can attach a collection such as a vector or hashtable, then attach your application information to that.)

  Important Note: You are responsible for removing references to your data on nodes that are no longer used. Failure to do so will prevent the nodes, your data is attached to, to be garbage collected until the whole document is.

  Parameters:
    `data` - the object to store or null to remove any existing reference

### setUserData

    public Object setUserData(String key,
                              Object data,
                              org.apache.xerces.dom3.UserDataHandler handler)

  Deprecated.
  Associate an object to a key on this node. The object can later be retrieved from this node by calling `getUserData` with the same key.

  Parameters:
    `key` - The key to associate the object to.
    `data` - The object to associate to the given key, or `null` to remove any existing association to that key.
    `handler` - The handler to associate to that key, or `null`.
  Returns:
    Returns the `DOMObject` previously associated to the given key on this node, or `null` if there was none.
  Since:
    DOM Level 3

### synchronizeData

    protected void synchronizeData()

  Deprecated.
  Override this method in subclass to hook in efficient internal data structure.

### toString

    public String toString()

  Deprecated.
  NON-DOM method for debugging convenience.
