Constructor Detail

### QualifiedName

    public QualifiedName(INamespace namespace,
                         String name)
                  throws IllegalArgumentException

  Construct a new QualifiedName with the given namespace and object name.

Parameters:
  `namespace` - The namespace portion of this QualifiedName, or null if there is to be no namespace.
  `name` - The object name portion of this QualifiedName. Null is not allowed.
Throws:
  `IllegalArgumentException` - If the name parameter is null.

Method Detail

### getNamespace

    public INamespace getNamespace()

  Return the namespace portion of this QualifiedName.

  Returns:
    The namespace portion of this QualifiedName, or null if none has been set.

### setNamespace

    public void setNamespace(INamespace namespace)

  Set the namespace portion of this QualifiedName.

  Parameters:
    `namespace` - The new namespace, or null if there is to be no namespace.

### getName

    public String getName()

  Return the object name portion of this QualifiedName.

  Returns:
    The object name portion of this QualifiedName. This should never be null.

### setName

    public void setName(String name)
                 throws IllegalArgumentException

  Set the name portion of this QualifiedName.

  Parameters:
    `name` - The new object name. Null is not allowed.
  Throws:
    `IllegalArgumentException` - If the new name is null.

### getComponents

    public Iterator getComponents()

  Get an Iterator over the components of this qualified name. Each component is returned as a QualifiedName, starting with the first component that is not the root namespace. For example, if a namespace with name foo existing in the root namespace, and foo contained an object named bar, the getComponents method would return an Iterator over two components. This first component is a QualifiedName with namespace equal to the root namespace and name equal 'foo'. The second component is a QualifiedName with namespace equal to foo and name equal 'bar'.

  Returns:
    An iterator over the components (QualifiedName) of this qualified name.

### toString

    public String toString()

  Return a string representation of this QualifiedName. Its returned in namespace.name format.

  Returns:
    The string representation of this object.

### equals

    public boolean equals(Object obj)

  Compare this object to the given object and determine if they are equal. For QualifiedNames, this means that both the namespace and name must be equal.

  Returns:
    True if the name and namespace of the obj param equal this QualifiedName's name and namespace.

### hashCode

    public int hashCode()

  Return a hash used to store QualifiedNames into hash tables, and retrieve them.

  Returns:
    A hash value representing the toString() value for this object.
