# Uses of Package
org.apache.xpath.axes

- Packages that use org.apache.xpath.axes
  Package | Description
  --- | ---
  org.apache.xalan.templates | Implements the `Templates` interface, and defines a set of classes that represent an XSLT stylesheet.
  org.apache.xalan.transformer | In charge of run-time transformations and the production of result trees.
  org.apache.xpath | Implementation of XPath; for the most part, only classes meant for public use are found at this root level of the XPath packages.
  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.
  org.apache.xpath.patterns | Implementation of XPath nodeTest support, and XSLT pattern matching support.

- Classes in org.apache.xpath.axes used by org.apache.xalan.templates
  Class and Description
  LocPathIterator This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath
  Classes in org.apache.xpath.axes used by org.apache.xalan.transformer
  Class and Description
  BasicTestIterator Base for iterators that handle predicates.
  ChildTestIterator This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
  LocPathIterator This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath | 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.)
  PathComponent Classes who implement this information provide information needed for static analysis of a path component.
  PredicatedNodeTest
  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.

- Classes in org.apache.xpath.axes used by org.apache.xpath
  Class and Description
  ContextNodeList Classes who implement this interface can be a current node list, also refered to here as a context node list.
  LocPathIterator This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath | 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.
  UnionPathIterator This class extends NodeSetDTM, which implements DTMIterator, and fetches nodes one at a time in document order based on a XPath UnionExpr.

- Classes in org.apache.xpath.axes used by org.apache.xpath.axes
  Class and Description
  AxesWalker Serves as common interface for axes Walkers, and stores common state variables.
  BasicTestIterator Base for iterators that handle predicates.
  ChildTestIterator This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
  LocPathIterator This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath | PathComponent Classes who implement this information provide information needed for static analysis of a path component.
