Description

Class Summary

AncestorContext	EvalContext that walks the "ancestor::" and "ancestor-or-self::" axes.
AttributeContext	EvalContext that walks the "attribute::" axis.
ChildContext	EvalContext that can walk the "child::", "following-sibling::" and "preceding-sibling::" axes.
DescendantContext	An EvalContext that walks the "descendant::" and "descendant-or-self::" axes.
InitialContext	A single-set EvalContext that provides access to the current node of the parent context and nothing else.
NamespaceContext	EvalContext that walks the "namespace::" axis.
NodeSetContext	A simple context that is based on a NodeSet.
ParentContext	EvalContext that walks the "parent::" axis.
PrecedingOrFollowingContext	EvalContext that walks the "preceding::" and "following::" axes.
PredicateContext	EvalContext that checks predicates.
RootContext	EvalContext that is used to hold the root node for the path traversal.
SelfContext	EvalContext that returns the current node from the parent context if the test succeeds.
SimplePathInterpreter	An evaluation mechanism for simple XPaths, which is much faster than the usual process.
UnionContext	EvalContext that represents a union between other contexts - result of a union operation like (a | b)

Package org.apache.commons.jxpath.ri.axes Description

Implementations of EvalContext used for different XPath axes (child::, parent:: etc). In order to evaluate a path, RI creates a chain of EvalContexts, one for each step in the path.
