Description

Interface Summary

CompiledExpression	Represents a compiled XPath.
Container	A Container is an object implementing an indirection mechanism transparent to JXPath.
DynamicPropertyHandler	A generic mechanism for accessing collections of name/value pairs.
ExpressionContext	If an extenstion function has an argument of type ExpressionContext, it can gain access to the current node of an XPath expression context.
Function	Extension function interface.
Functions	A group of Function objects sharing a common namespace or a set of common namespaces.
IdentityManager	A delegate of JXPathContext that implements the XPath "id()" function.
JXPathBeanInfo	JXPathBeanInfo is similar to java.beans.BeanInfo in that it describes properties of a JavaBean class.
KeyManager	A delegate of JXPathContext that implements the XPath "key()" function.
NodeSet	NodeSet interface can be used as the type of an argument of an extension function.
Pointer	Pointers represent locations of objects and their properties in Java object graphs.
Variables	Variables provide access to a global set of values accessible via XPath.

Class Summary

AbstractFactory	The JXPathContext.createPath() method of JXPathContext can create missing objects as it traverses an XPath; it utilizes an AbstractFactory for that purpose.
BasicNodeSet	A simple implementation of NodeSet that behaves as a collection of pointers.
BasicVariables	A basic implementation of the Variables interface that uses a HashMap.
ClassFunctions	Extension functions provided by a Java class.
FunctionLibrary	An object that aggregates Functions objects into a group Functions object.
JXPathBasicBeanInfo	An implementation of JXPathBeanInfo based on JavaBeans' BeanInfo.
JXPathContext	JXPathContext provides APIs for the traversal of graphs of JavaBeans using the XPath syntax.
JXPathContextFactory	Defines a factory API that enables applications to obtain a JXPathContext instance.
JXPathIntrospector	JXPathIntrospector maintains a registry of JXPathBeanInfo objects for Java classes.
MapDynamicPropertyHandler	Implements the DynamicPropertyHandler interface for java.util.Map.
PackageFunctions	Extension functions provided by Java classes.
XMLDocumentContainer	Deprecated. 1.1 Please use org.apache.commons.jxpath.xml.DocumentContainer

Exception Summary

JXPathException

Thrown in various situations by JXPath; may contain a nested exception.

Error Summary

JXPathContextFactoryConfigurationError

Thrown when a problem with configuration with the JXPathContextFactories exists.

Package org.apache.commons.jxpath Description

Public, abstract part of JXPath: interfaces and configuration. If you are a user of JXPath and don't plan to modify its implementation, this is the only package you'll need to use. Start with the JXPathContext class.
