Method Details

attributeIterator

public NodeIterator attributeIterator(QName name)
Overrides:
attributeIterator in interface NodePointer

childIterator

public NodeIterator childIterator(NodeTest test,
                                  boolean reverse,
                                  NodePointer startWith)
Overrides:
childIterator in interface NodePointer

compareChildNodePointers

public int compareChildNodePointers(NodePointer pointer1,
                                    NodePointer pointer2)
Overrides:
compareChildNodePointers in interface NodePointer

createNodeIterator

public NodeIterator createNodeIterator(String property,
                                       boolean reverse,
                                       NodePointer startWith)

getImmediateNode

public Object getImmediateNode()
Overrides:
getImmediateNode in interface NodePointer

getName

public abstract QName getName()
Overrides:
getName in interface NodePointer

getPropertyPointer

public abstract PropertyPointer getPropertyPointer()

isDynamicPropertyDeclarationSupported

public boolean isDynamicPropertyDeclarationSupported()
Returns:
true if the property owner can set a property "does not exist". A good example is a Map. You can always assign a value to any key even if it has never been "declared".

remove

public void remove()
If this is a root node pointer, throws an exception; otherwise forwards the call to the parent node.
Overrides:
remove in interface NodePointer

setIndex

public void setIndex(int index)
Overrides:
setIndex in interface NodePointer

setValue

public void setValue(Object value)
Throws an exception if you try to change the root element, otherwise forwards the call to the parent pointer.
Specified by:
setValue in interface Pointer
Overrides:
setValue in interface NodePointer
