Interface Summary
ContextNodeList Classes who implement this interface can be a current node list, also refered to here as a context node list.
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
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.
FilterExprIterator  
FilterExprIteratorSimple Class to use for one-step iteration that doesn't have a predicate, and doesn't need to set the context.
FilterExprWalker Walker for the OP_VARIABLE, or OP_EXTFUNCTION, 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 MatchPatternIterator This class treats a LocationPath as a filtered iteration over the tree, evaluating each node in a super axis traversal against the LocationPath interpreted as a match pattern.
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.
RTFIterator  
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.
