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

| Java Source File Name | Type | Comment |
| AttributeIterator.java | Class | This class implements an optimized iterator for
attribute axes patterns. |
| AxesWalker.java | Class | Serves as common interface for axes Walkers, and stores common
state variables. |
| BasicTestIterator.java | Class | Base for iterators that handle predicates. |
| ChildIterator.java | Class | This class implements an optimized iterator for
"node()" patterns, that is, any children of the
context node. |
| ChildTestIterator.java | Class | This class implements an optimized iterator for
children patterns that have a node test, and possibly a predicate. |
| ContextNodeList.java | Interface | Classes who implement this interface can be a
current node list,
also refered to here as a context node list. |
| DescendantIterator.java | Class | This class implements an optimized iterator for
descendant, descendant-or-self, or "//foo" patterns. |
| FilterExprIterator.java | Class | |
| FilterExprIteratorSimple.java | Class | Class to use for one-step iteration that doesn't have a predicate, and
doesn't need to set the context. |
| FilterExprWalker.java | Class | Walker for the OP_VARIABLE, or OP_EXTFUNCTION, or OP_FUNCTION, or OP_GROUP,
op codes. |
| HasPositionalPredChecker.java | Class | |
| IteratorPool.java | Class | |
| LocPathIterator.java | Class | This class extends NodeSetDTM, which implements NodeIterator,
and fetches nodes one at a time in document order based on a XPath
MatchPatternIterator.java | Class | 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.java | Class | This class is the dynamic wrapper for a Xalan DTMIterator instance, and
provides random access capabilities. |
| OneStepIterator.java | Class | This class implements a general iterator for
those LocationSteps with only one step, and perhaps a predicate. |
| OneStepIteratorForward.java | Class | This class implements a general iterator for
those LocationSteps with only one step, and perhaps a predicate,
that only go forward (i.e. |
| PathComponent.java | Interface | Classes who implement this information provide information needed for
static analysis of a path component. |
| PredicatedNodeTest.java | Class | |
| ReverseAxesWalker.java | Class | Walker for a reverse axes. |
| RTFIterator.java | Class | |
| SelfIteratorNoPredicate.java | Class | This class implements an optimized iterator for
"." patterns, that is, the self axes without any predicates. |
| SubContextList.java | Interface | 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. |
| UnionChildIterator.java | Class | This class defines a simplified type of union iterator that only
tests along the child axes. |
| UnionPathIterator.java | Class | This class extends NodeSetDTM, which implements DTMIterator,
and fetches nodes one at a time in document order based on a XPath
UnionExpr. |
| WalkerFactory.java | Class | 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.java | Class | Location path iterator that uses Walkers. |
| WalkingIteratorSorted.java | Class | This class iterates over set of nodes that needs to be sorted. |
