Description
| Interface Summary | |
| ContextNodeList | Classes who implement this interface can be a
current node list,
also refered to here as a |
| 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 LocationPath. |
| 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. |
Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
