org.apache.xpath.axes.PathComponent

Packages that use PathComponent

Package	Description
org.apache.xalan.transformer	In charge of run-time transformations and the production of result trees.
org.apache.xpath.axes	Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
org.apache.xpath.objects	Implementation of XPath polymorphic type objects -- this package will grow as XPath objects are expanded to support XML Schema data types.
org.apache.xpath.operations	Support for XPath operations, such as +, -, string(), etc.

Uses of PathComponent in org.apache.xalan.transformer

Classes in org.apache.xalan.transformer that implement PathComponent

Modifier and Type	Class and Description
class	KeyIterator This class implements an optimized iterator for "key()" patterns, matching each node to the match attribute in one or more xsl:key declarations.
class	KeyRefIterator This class filters nodes from a key iterator, according to whether or not the use value matches the ref value.

Uses of PathComponent in org.apache.xpath.axes

Classes in org.apache.xpath.axes that implement PathComponent

Modifier and Type	Class and Description
class	AttributeIterator This class implements an optimized iterator for attribute axes patterns.
class	AxesWalker Serves as common interface for axes Walkers, and stores common state variables.
class	BasicTestIterator Base for iterators that handle predicates.
class	ChildIterator This class implements an optimized iterator for "node()" patterns, that is, any children of the context node.
class	ChildTestIterator This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
class	DescendantIterator This class implements an optimized iterator for descendant, descendant-or-self, or "//foo" patterns.
class	FilterExprIterator
class	FilterExprIteratorSimple Class to use for one-step iteration that doesn't have a predicate, and doesn't need to set the context.
class	FilterExprWalker Walker for the OP_VARIABLE, or OP_EXTFUNCTION, or OP_FUNCTION, or OP_GROUP, op codes.
class	LocPathIterator This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath	class	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.
class	NodeSequence This class is the dynamic wrapper for a Xalan DTMIterator instance, and provides random access capabilities.
class	OneStepIterator This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate.
class	OneStepIteratorForward This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate, that only go forward (i.e.
class	ReverseAxesWalker Walker for a reverse axes.
class	SelfIteratorNoPredicate This class implements an optimized iterator for "." patterns, that is, the self axes without any predicates.
class	UnionChildIterator This class defines a simplified type of union iterator that only tests along the child axes.
class	UnionPathIterator This class extends NodeSetDTM, which implements DTMIterator, and fetches nodes one at a time in document order based on a XPath UnionExpr.
class	WalkingIterator Location path iterator that uses Walkers.
class	WalkingIteratorSorted This class iterates over set of nodes that needs to be sorted.

Uses of PathComponent in org.apache.xpath.objects

Classes in org.apache.xpath.objects that implement PathComponent

Modifier and Type	Class and Description
class	XNodeSet This class represents an XPath nodeset object, and is capable of converting the nodeset to other types, such as a string.
class	XNodeSetForDOM This class overrides the XNodeSet#object() method to provide the original Node object, NodeList object, or NodeIterator.
class	XNull This class represents an XPath null object, and is capable of converting the null to other types, such as a string.

Uses of PathComponent in org.apache.xpath.operations

Classes in org.apache.xpath.operations that implement PathComponent

Modifier and Type	Class and Description
class	Variable The variable reference expression executer.
class	VariableSafeAbsRef This is a "smart" variable reference that is used in situations where an absolute path is optimized into a variable reference, but may be used in some situations where the document context may have changed.
