Package Samples:

• org.apache.xpath.axes

Classes:

• LocPathIterator: This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath LocationPath . If setShouldCacheNodes(true) is called, as each node is iterated via nextNode(), the node is also stored in the NodeVector, so that previousNode() can easily be done, except in the case where the LocPathIterator is "owned" by a UnionPathIterator, in which case the UnionPathIterator will cache the nodes.
• 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. This class is useful to find nodes in document order that are complex paths whose steps probably criss-cross each other.
• UnionPathIterator: This class extends NodeSetDTM, which implements DTMIterator, and fetches nodes one at a time in document order based on a XPath UnionExpr . As each node is iterated via nextNode(), the node is also stored in the NodeVector, so that previousNode() can easily be done.
• 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.
• OneStepIteratorForward: This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate, that only go forward (i.e. it can not be used with ancestors, preceding, etc.)
• ContextNodeList: Classes who implement this interface can be a current node list , also refered to here as a context node list .
• UnionChildIterator: This class defines a simplified type of union iterator that only tests along the child axes. If the conditions are right, it is much faster than using a UnionPathIterator.
• BasicTestIterator: Base for iterators that handle predicates. Does the basic next node logic, so all the derived iterator has to do is get the next node.
• 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.
• ChildTestIterator: This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
• ChildIterator: This class implements an optimized iterator for "node()" patterns, that is, any children of the context node.
• 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.
• SelfIteratorNoPredicate: This class implements an optimized iterator for "." patterns, that is, the self axes without any predicates.
• PathComponent: Classes who implement this information provide information needed for static analysis of a path component.
• FilterExprIteratorSimple: Class to use for one-step iteration that doesn't have a predicate, and doesn't need to set the context.
• 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.
• AxesWalker: Serves as common interface for axes Walkers, and stores common state variables.
• AttributeIterator: This class implements an optimized iterator for attribute axes patterns.
• IteratorPool: Pool of object of a given type to pick from to help memory usage
• WalkingIteratorSorted: This class iterates over set of nodes that needs to be sorted.
• WalkingIterator: Location path iterator that uses Walkers.
• ReverseAxesWalker: Walker for a reverse axes.
• HasPositionalPredChecker
