org.apache.commons.jxpath

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.

Interface Summary
Interface	Description
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.
ExtendedKeyManager	More complete implementation for the XPath `"key()"` function.
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 `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
Class	Description
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 `Map`.
PackageFunctions	Extension functions provided by Java classes.
XMLDocumentContainer	Deprecated. 1.1 Please use `DocumentContainer`

Exception Summary
Exception	Description
JXPathAbstractFactoryException	Thrown when an `AbstractFactory` cannot generate an object for the requested path.
JXPathException	Thrown in various situations by JXPath; may contain a nested exception.
JXPathFunctionNotFoundException	Thrown when JXPath encounters an unknown extension function.
JXPathInvalidAccessException	Similary to `InvocationTargetException` in that it is thrown when JXPath cannot access properties, collection etc on the target object model.
JXPathInvalidSyntaxException	Thrown when JXPath cannot parse a supplied XPath.
JXPathNotFoundException	Thrown when JXPath cannot find a requested path.
JXPathTypeConversionException	Thrown when JXPath cannot convert supplied value to the required type.
