public class ProcessingInstructionImpl
extends CharacterDataImpl
implements org.w3c.dom.ProcessingInstruction

Processing Instructions (PIs) permit documents to carry processor-specific information alongside their actual content. PIs are most common in XML, but they are supported in HTML as well. This class inherits from CharacterDataImpl to reuse its setNodeValue method.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Field Detail

### target

    protected java.lang.String target

Constructor Detail

### ProcessingInstructionImpl

    public ProcessingInstructionImpl(DocumentImpl ownerDoc,
                                     java.lang.String target,
                                     java.lang.String data)

  Factory constructor.

Method Detail

### getNodeType

    public short getNodeType()

  A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.

  Overrides:
    getNodeType in class NodeImpl

### getNodeName

    public java.lang.String getNodeName()

  Returns the target

  Overrides:
    getNodeName in class NodeImpl

### getTarget

    public java.lang.String getTarget()

  A PI's "target" states what processor channel the PI's data should be directed to. It is defined differently in HTML and XML.

  In XML, a PI's "target" is the first (whitespace-delimited) token following the " In HTML, target is always null.

  Note that getNodeName is aliased to getTarget.

  Specified by:
    getTarget in interface org.w3c.dom.ProcessingInstruction

### getData

    public java.lang.String getData()

  A PI's data content tells the processor what we actually want it to do. It is defined slightly differently in HTML and XML.

  In XML, the data begins with the non-whitespace character immediately after the target -- @see getTarget().

  In HTML, the data begins with the character immediately after the "<?" token that begins the PI.

  Note that getNodeValue is aliased to getData

  Specified by:
    getData in interface org.w3c.dom.ProcessingInstruction

  Overrides:
    getData in class CharacterDataImpl

### setData

    public void setData(java.lang.String data)

  Change the data content of this PI. Note that setData is aliased to setNodeValue.
  Specified by:
    setData in interface org.w3c.dom.ProcessingInstruction

  Throws:
    DOMException(NO_MODIFICATION_ALLOWED_ERR) - if node is read-only.
  Overrides:
    setData in class CharacterDataImpl
  See Also:
    `getData().`
