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