| Method Summary | |
| public static void | addNodePointerFactory(NodePointerFactory factory)
Call this with a custom NodePointerFactory to add support for
additional types of objects. | | public static Object | allocateConditionally(String className, String existenceCheckClassName)
Checks if existenceCheckClass exists on the class path. | | protected CompiledExpression | compilePath(String xpath)
| | public Pointer | createPath(String xpath)
| | public Pointer | createPath(String xpath, Expression expr)
| | public Pointer | createPathAndSetValue(String xpath, Object value)
| | public Pointer | createPathAndSetValue(String xpath, Expression expr, Object value)
| | public EvalContext | getAbsoluteRootContext()
| | protected Compiler | getCompiler()
Returns a static instance of TreeCompiler. | | public Pointer | getContextPointer()
| | public Function | getFunction(QName functionName, Object[] parameters)
| | public Pointer | getNamespaceContextPointer()
| | public NamespaceResolver | getNamespaceResolver()
| | public String | getNamespaceURI(String prefix)
| | public static NodePointerFactory[] | getNodePointerFactories()
| | public Pointer | getPointer(String xpath)
| | public Pointer | getPointer(String xpath, Expression expr)
| | public JXPathContext | getRelativeContext(Pointer pointer)
| | public Object | getValue(String xpath)
Traverses the xpath and returns the resulting object. | | public Object | getValue(String xpath, Expression expr)
| | public Object | getValue(String xpath, Class requiredType)
Calls getValue(xpath), converts the result to the required type
and returns the result of the conversion. | | public Object | getValue(String xpath, Expression expr, Class requiredType)
| | public NodePointer | getVariablePointer(QName name)
| | public Iterator | iterate(String xpath)
Traverses the xpath and returns a Iterator of all results found
for the path. | | public Iterator | iterate(String xpath, Expression expr)
| | public Iterator | iteratePointers(String xpath)
Traverses the xpath and returns an Iterator of Pointers. | | public Iterator | iteratePointers(String xpath, Expression expr)
| | public void | registerNamespace(String prefix, String namespaceURI)
| | public void | removeAll(String xpath)
| | public void | removeAll(String xpath, Expression expr)
| | public void | removePath(String xpath)
| | public void | removePath(String xpath, Expression expr)
| | public void | setNamespaceContextPointer(Pointer pointer)
| | public void | setValue(String xpath, Object value)
| | public void | setValue(String xpath, Expression expr, Object value)
|
| USE_SOFT_CACHE | | final public static boolean USE_SOFT_CACHE(Code) | | Change this to false to disable soft caching of
CompiledExpressions.
|
| addNodePointerFactory | | public static void addNodePointerFactory(NodePointerFactory factory)(Code) | | Call this with a custom NodePointerFactory to add support for
additional types of objects. Make sure the factory returns
a name that puts it in the right position on the list of factories.
|
| allocateConditionally | | public static Object allocateConditionally(String className, String existenceCheckClassName)(Code) | | Checks if existenceCheckClass exists on the class path. If so, allocates
an instance of the specified class, otherwise returns null.
|
| getCompiler | | protected Compiler getCompiler()(Code) | | Returns a static instance of TreeCompiler.
Override this to return an aternate compiler.
|
| getNamespaceContextPointer | | public Pointer getNamespaceContextPointer()(Code) | | |
| getValue | | public Object getValue(String xpath)(Code) | | Traverses the xpath and returns the resulting object. Primitive
types are wrapped into objects.
|
| getValue | | public Object getValue(String xpath, Class requiredType)(Code) | | Calls getValue(xpath), converts the result to the required type
and returns the result of the conversion.
|
| iterate | | public Iterator iterate(String xpath)(Code) | | Traverses the xpath and returns a Iterator of all results found
for the path. If the xpath matches no properties
in the graph, the Iterator will not be null.
|
| iteratePointers | | public Iterator iteratePointers(String xpath)(Code) | | Traverses the xpath and returns an Iterator of Pointers.
A Pointer provides easy access to a property.
If the xpath matches no properties
in the graph, the Iterator be empty, but not null.

| setNamespaceContextPointer | | public void setNamespaceContextPointer(Pointer pointer)(Code) | | |
