Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.

Interface Summary

Interface	Description
PathComponent	Classes who implement this information provide information needed for static analysis of a path component.
SubContextList	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

Class	Description
AttributeIterator	This class implements an optimized iterator for attribute axes patterns.
AxesWalker	Serves as common interface for axes Walkers, and stores common state variables.
BasicTestIterator	Base for iterators that handle predicates.
ChildIterator	This class implements an optimized iterator for "node()" patterns, that is, any children of the context node.
ChildTestIterator	This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
DescendantIterator	This class implements an optimized iterator for descendant, descendant-or-self, or "//foo" patterns.
FilterExprWalker	Walker for the OP_VARIABLE, or OP_FUNCTION, or OP_GROUP, op codes.
HasPositionalPredChecker
IteratorPool	Pool of object of a given type to pick from to help memory usage
LocPathIterator	This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath.
NodeSequence	This class is the dynamic wrapper for a Xalan DTMIterator instance, and provides random access capabilities.
OneStepIterator	This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate.
OneStepIteratorForward	This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate, that only go forward (i.e.
PredicatedNodeTest
ReverseAxesWalker	Walker for a reverse axes.
SelfIteratorNoPredicate	This class implements an optimized iterator for "." patterns, that is, the self axes without any predicates.
UnionChildIterator	This class defines a simplified type of union iterator that only tests along the child axes.
UnionPathIterator	This class extends NodeSetDTM, which implements DTMIterator, 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.
WalkingIterator	Location path iterator that uses Walkers.
WalkingIteratorSorted	This class iterates over set of nodes that needs to be sorted.
