boolean	equals(Object object)
Object	getBaseValue()	Gets the value represented by the pointer before indexing.
Object	getImmediateNode()	Returns the object the pointer points to; does not convert it to a "canonical" type.
int	getLength()	If the pointer represents a collection (or collection element), returns the length of the collection.
QName	getName()	Gets the name of this node.
String	getNamespaceURI()	Returns the namespace URI associated with this Pointer.
int	hashCode()
boolean	isCollection()	Returns true if the value of the pointer is an array or a Collection.
boolean	isLeaf()	If true, this node does not have children
void	setValue(Object value)	Converts the value to the required type and changes the corresponding object to that value.
boolean	testNode(NodeTest test)	Checks if this Pointer matches the supplied NodeTest.

Constructor Details

LangAttributePointer

public LangAttributePointer(NodePointer parent)

Constructs a new LangAttributePointer.

Parameters:

parent - parent pointer.

Method Details

asPath

public String asPath()

Description copied from class: NodePointer

Returns an XPath that maps to this Pointer.

Specified by:

asPath in interface Pointer

Overrides:

asPath in class NodePointer

Returns:

String XPath expression

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.

Specified by:

compareChildNodePointers in class NodePointer

Parameters:

pointer1 - first pointer to be compared

pointer2 - second pointer to be compared

Returns:

int per Java comparison conventions

equals

public boolean equals(Object object)

Overrides:

equals in class Object

getBaseValue

public Object getBaseValue()

Description copied from class: NodePointer

Gets the value represented by the pointer before indexing. So, if the node represents an element of a collection, this method returns the collection itself.

Specified by:

getBaseValue in class NodePointer

Returns:

Object value

getImmediateNode

public Object getImmediateNode()

Description copied from class: NodePointer

Returns the object the pointer points to; does not convert it to a "canonical" type.

Specified by:

getImmediateNode in class NodePointer

Returns:

Object node

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).

Specified by:

getLength in class NodePointer

Returns:

the length.

getName

public QName getName()

Description copied from class: NodePointer

Gets the name of this node. Can be null.

Specified by:

getName in class NodePointer

Returns:

QName The name of this node. Can be null.

getNamespaceURI

public String getNamespaceURI()

Description copied from class: NodePointer

Returns the namespace URI associated with this Pointer.

Overrides:

getNamespaceURI in class NodePointer

Returns:

String uri

hashCode

public int hashCode()

Overrides:

hashCode in class Object

isCollection

public boolean isCollection()

Description copied from class: NodePointer

Returns true if the value of the pointer is an array or a Collection.

Specified by:

isCollection in class NodePointer

Returns:

boolean

isLeaf

public boolean isLeaf()

Description copied from class: NodePointer

If true, this node does not have children

Specified by:

isLeaf in class NodePointer

Returns:

boolean

setValue

public void setValue(Object value)

Converts the value to the required type and changes the corresponding object to that value. Throws UnsupportedOperationException.

Specified by:

setValue in interface Pointer

Specified by:

setValue in class NodePointer

Parameters:

value - Object

testNode

public boolean testNode(NodeTest test)

Description copied from class: NodePointer

Checks if this Pointer matches the supplied NodeTest.

Overrides:

testNode in class NodePointer

Parameters:

test - the NodeTest to execute

Returns:

true if a match
