Constructor Summary

NodePointer(NodePointer parent)

NodePointer(NodePointer parent, Locale locale)

Method Summary
String	asPath() Returns an XPath that maps to this Pointer.
NodeIterator	attributeIterator(QName qname) Returns a NodeIterator that iterates over all attributes of the current node matching the supplied node name (could have a wildcard).
NodeIterator	childIterator(NodeTest test, boolean reverse, NodePointer startWith) Returns a NodeIterator that iterates over all children or all children that match the given NodeTest, starting with the specified one.
Object	clone() Pointers are cloneable
abstract int	compareChildNodePointers(NodePointer pointer1, NodePointer pointer2) Compares two child NodePointers and returns a positive number, zero or a positive number according to the order of the pointers.
int	compareTo(Object object)
NodePointer	createAttribute(JXPathContext context, QName name) Called to create a non-existing attribute
NodePointer	createChild(JXPathContext context, QName name, int index) Called by a child pointer when it needs to create a parent object for a non-existent collection element.
NodePointer	createChild(JXPathContext context, QName name, int index, Object value) Called by a child pointer if that child needs to assign the value supplied in the createPath(context, value) call to a non-existent node.
NodePointer	createPath(JXPathContext context) Called by a child pointer when it needs to create a parent object.
NodePointer	createPath(JXPathContext context, Object value) Called directly by JXPathContext.
abstract Object	getBaseValue() Returns the value represented by the pointer before indexing.
protected String	getDefaultNamespaceURI()
abstract Object	getImmediateNode() Returns the object the pointer points to; does not convert it to a "canonical" type.
NodePointer	getImmediateParentPointer()
NodePointer	getImmediateValuePointer()
int	getIndex() If the pointer represents a collection, the index identifies an element of that collection.
abstract int	getLength() If the pointer represents a collection (or collection element), returns the length of the collection.
Locale	getLocale() If the Pointer has a parent, returns the parent's locale; otherwise returns the locale specified when this Pointer was created.
abstract QName	getName() Returns the name of this node.
NamespaceResolver	getNamespaceResolver()
String	getNamespaceURI() Returns the namespace URI associated with this Pointer.
String	getNamespaceURI(String prefix) Decodes a namespace prefix to the corresponding URI.
Object	getNode() Returns the object the pointer points to; does not convert it to a "canonical" type.
Object	getNodeValue() Deprecated. 1.1 Please use getNode()
NodePointer	getParent()
Pointer	getPointerByID(JXPathContext context, String id) Locates a node by ID.
Pointer	getPointerByKey(JXPathContext context, String key, String value) Locates a node by key and value.
Object	getRootNode() Returns the node this pointer is based on.
Object	getValue() By default, returns getNode(), can be overridden to return a "canonical" value, like for instance a DOM element should return its string value.
NodePointer	getValuePointer() If this pointer manages a transparent container, like a variable, this method returns the pointer to the contents.
boolean	isActual() An actual pointer points to an existing part of an object graph, even if it is null.
boolean	isAttribute() Returns true if the pointer represents the "attribute::" axis.
abstract boolean	isCollection() Returns true if the value of the pointer is an array or a Collection.
boolean	isContainer() If true, this node is axiliary and can only be used as an intermediate in the chain of pointers.
protected boolean	isDefaultNamespace(String prefix) Returns true if the supplied prefix represents the default namespace in the context of the current node.
boolean	isLanguage(String lang) Returns true if the selected locale name starts with the specified prefix lang, case-insensitive.
abstract boolean	isLeaf() If true, this node does not have children
boolean	isNode() Deprecated. Please use !isContainer()
boolean	isRoot() Returns true if this Pointer has no parent.
NodeIterator	namespaceIterator() Returns a NodeIterator that iterates over all namespaces of the value currently pointed at.
NodePointer	namespacePointer(String namespace) Returns a NodePointer for the specified namespace.
static NodePointer	newChildNodePointer(NodePointer parent, QName name, Object bean) Allocates an new child NodePointer by iterating through all installed NodePointerFactories until it finds one that can create a pointer.
static NodePointer	newNodePointer(QName name, Object bean, Locale locale) Allocates an entirely new NodePointer by iterating through all installed NodePointerFactories until it finds one that can create a pointer.
void	printPointerChain() Print internal structure of a pointer for debugging
void	remove() Remove the node of the object graph this pointer points to.
void	setAttribute(boolean attribute) Set to true if the pointer represents the "attribute::" axis.
void	setIndex(int index)
void	setNamespaceResolver(NamespaceResolver namespaceResolver)
abstract 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.
String	toString()
