Package org.jaxen

This package defines the core Jaxen API to the XPath engine.

Interface Summary

Interface	Description
Function	Interface for the extensible function framework.
FunctionContext	Implemented by classes that know how to resolve XPath function names and namespaces to implementations of these functions.
NamedAccessNavigator	Interface for navigating around an arbitrary object model accessing certain parts by name for performance.
NamespaceContext	Resolves namespace prefixes to namespace URIs.
Navigator	Interface for navigating around an arbitrary object model, using XPath semantics.
VariableContext	Resolves variable bindings within an XPath expression.
XPath	Represents an XPath 1.0 expression which can be evaluated against a variety of different XML object models.

Class Summary

Class	Description
BaseXPath	Base functionality for all concrete, implementation-specific XPaths.
Context	Wrapper around implementation-specific objects used as the context of an expression evaluation.
ContextSupport	Supporting context information for resolving namespace prefixes, functions, and variables.
DefaultNavigator	Default implementation of Navigator.
JaxenConstants	Thread-safe constant iterators used to avoid the overhead of creating empty lists.
JaxenHandler	SAXPath XPathHandler implementation capable of building Jaxen expression trees which can walk various different object models.
SimpleFunctionContext	Simple default implementation of FunctionContext.
SimpleNamespaceContext	Provides mappings from namespace prefix to namespace URI to the XPath engine.
SimpleVariableContext	Simple default implementation for VariableContext.
XPathFunctionContext	A FunctionContext implementing the core XPath function library, plus Jaxen extensions.

Exception Summary

Exception	Description
FunctionCallException	Thrown if an exception occurs during the evaluation of a function.
JaxenException	Generic Jaxen exception.
JaxenRuntimeException	This class exists to wrap Jaxen exceptions that otherwise wouldn't be propagated up through the axis iterators.
UnresolvableException	Thrown when a function-call or variable-reference, or any other lookup based on namespace and local name, couldn't be resolved.
UnsupportedAxisException	Indicates attempt to evaluate an XPath axis that is unsupported by the current object-model.
XPathSyntaxException	Indicates an error during parsing of an XPath expression.

Package org.jaxen Description

This package defines the core Jaxen API to the XPath engine. Using this API you can work with XPath on any object model.
