JDOMNamespacePointer

public JDOMNamespacePointer(NodePointer parent,
                            java.lang.String prefix)

JDOMNamespacePointer

public JDOMNamespacePointer(NodePointer parent,
                            java.lang.String prefix,
                            java.lang.String namespaceURI)
Method Detail

getName

public QName getName()
Description copied from class: NodePointer
Returns the name of this node. Can be null.
Overrides:
getName in class NodePointer

getBaseValue

public java.lang.Object getBaseValue()
Description copied from class: NodePointer
Returns the value represented by the pointer before indexing. So, if the node represents an element of a collection, this method returns the collection itself.
Overrides:
getBaseValue in class NodePointer

isCollection

public boolean isCollection()
Description copied from class: NodePointer
Returns true if the value of the pointer is an array or a Collection.
Overrides:
isCollection in class NodePointer

getLength

public int getLength()
Description copied from class: NodePointer
If the pointer represents a collection (or collection element), returns the length of the collection. Otherwise returns 1 (even if the value is null).
Overrides:
getLength in class NodePointer

getImmediateNode

public java.lang.Object getImmediateNode()
Description copied from class: NodePointer
Returns the object the pointer points to; does not convert it to a "canonical" type.
Overrides:
getImmediateNode in class NodePointer

getNamespaceURI

public java.lang.String getNamespaceURI()
Description copied from class: NodePointer
Returns the namespace URI associated with this Pointer.
Overrides:
getNamespaceURI in class NodePointer

isLeaf

public boolean isLeaf()
Description copied from class: NodePointer
If true, this node does not have children
Overrides:
isLeaf in class NodePointer

setValue

public void setValue(java.lang.Object value)
Throws UnsupportedOperationException.
Overrides:
setValue in class NodePointer

asPath

public java.lang.String asPath()
Description copied from class: NodePointer
Returns an XPath that maps to this Pointer.
Overrides:
asPath in class NodePointer

hashCode

public int hashCode()
Overrides:
hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object object)
Overrides:
equals in class java.lang.Object

compareChildNodePointers

public int compareChildNodePointers(NodePointer pointer1,
                                    NodePointer pointer2)
Description copied from class: NodePointer
Compares two child NodePointers and returns a positive number, zero or a positive number according to the order of the pointers.
Overrides:
compareChildNodePointers in class NodePointer
