Interface Summary

ContextNodeList	**For advanced use only** Classes who implement this interface can be a current node list, also refered to here as a context node list.
SubContextList	**For advanced use only** A class that implements this interface is a sub context node list, meaning it is a node list for a location path step for a predicate.

Class Summary

AncestorOrSelfWalker	Walker for the 'ancestor-or-self' axes.
AncestorWalker	Walker for the 'ancestor' axes.
AttributeIterator	**For advanced use only** This class implements an optimized iterator for attribute axes patterns.
AttributeWalker	Walker for the 'attribute' axes.
AttributeWalkerOneStep	**For advanced use only** This walker should be used when the walker is at the end of a location path, or is the only step.
AxesWalker	Serves as common interface for axes Walkers, and stores common state variables.
ChildIterator	**For advanced use only** This class implements an optimized iterator for "node()" patterns, that is, any children of the context node.
ChildTestIterator	**For advanced use only** This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
ChildWalker	Walker for the 'child' axes.
ChildWalkerMultiStep	**For advanced use only** A child walker multistep is created while only child steps are found.
ChildWalkerOneStep	**For advanced use only** Walker to use when we only have one step, but it has a predicate.
DescendantIterator	**For advanced use only** This class implements an optimized iterator for descendant, descendant-or-self, or "//foo" patterns.
DescendantOrSelfWalker	Walker for the 'descendant-or-self' axes.
DescendantWalker	Walker for the 'descendant' axes.
FilterExprWalker	Walker for the OP_VARIABLE, or OP_EXTFUNCTION, or OP_FUNCTION, or OP_GROUP, op codes.
FollowingSiblingWalker	Walker for the 'following-sibling' axes.
FollowingWalker	Walker for the 'following' axes.
LocPathIterator	**For advanced use only** This class extends NodeSet, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath	NamespaceWalker	Walker for the 'namespace' axes.
ParentWalker	Walker for the 'parent' axes.
PrecedingSiblingWalker	Walker for the 'preceding-sibling' axes.
PrecedingWalker	Walker for the 'preceding' axes.
PredicatedNodeTest
ReverseAxesWalker	Walker for a reverse axes.
RootWalker	Walker for the FROM_ROOT axes.
RootWalkerMultiStep	This class extends ChildWalkerMultiStep to handle the root step of patterns such as "/foo/baz" where the first step is the root, and the rest of the steps are simple child steps.
SelfWalker	Walker for the 'self' axes.
SelfWalkerOneStep	**For advanced use only** Class SelfWalkerOneStep
UnionPathIterator	**For advanced use only** This class extends NodeSet, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath UnionExpr.
WalkerFactory	This class is both a factory for XPath location path expressions, which are built from the opcode map output, and an analysis engine for the location path expressions in order to provide optimization hints.
