Description copied from interface:
CompiledExpression
Evaluates the xpath and returns the resulting object. Primitive
types are wrapped into objects.
Specified by:
getValue
in interface
CompiledExpression

CompiledExpression.getValue(JXPathContext)
Description copied from interface:
CompiledExpression
Evaluates the xpath, converts the result to the specified class and
returns the resulting object.
Specified by:
getValue
in interface

See Also:
CompiledExpression.getValue(JXPathContext, Class)
Description copied from interface:
CompiledExpression
Modifies the value of the property described by the supplied xpath.
Will throw an exception if one of the following conditions occurs:
The xpath does not in fact describe an existing property
The property is not writable (no public, non-static set method)

The same as setValue, except it creates intermediate elements of
the path by invoking an AbstractFactory, which should first be
installed on the context by calling "setFactory".
Will throw an exception if one of the following conditions occurs:
Elements of the xpath aleady exist, by the path does not in
fact describe an existing property
The AbstractFactory fails to create an instance for an intermediate
element.
The property is not writable (no public, non-static set method)

public java.util.Iterator
iterate
(
JXPathContext
context)
Description copied from interface:
CompiledExpression
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.
Specified by:
iterate
in interface
CompiledExpression
See Also:
CompiledExpression.iterate(JXPathContext)
Description copied from interface:
CompiledExpression
Traverses the xpath and returns a Pointer.
A Pointer provides easy access to a property.
If the xpath matches no properties
in the graph, the pointer will be null.
Specified by:
getPointer
in interface
CompiledExpression

CompiledExpression.getPointer(JXPathContext, String)
public java.util.Iterator
iteratePointers
(
JXPathContext
context)
Description copied from interface:
CompiledExpression
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.
Specified by:
iteratePointers
in interface
