## Package weblogic.apache.xpath.axes

Interface Summary
ContextNodeList | Classes who implement this interface can be a current node list, also refered to here as a context node list.
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.
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_EXTFUNCTION, or OP_FUNCTION, or OP_GROUP, op codes.
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.
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.
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 | NEEDSDOC Class WalkingIteratorSorted
