Package net.sf.saxon.tree.wrapper

This package defines a number of implementations of "virtual nodes" implemented as wrappers around other nodes.

Interface Summary

Interface	Description
SiblingCountingNode	Interface that extends NodeInfo by providing a method to get the position of a node relative to its siblings.
VirtualNode	This interface is implemented by NodeInfo implementations that act as wrappers on some underlying tree.
WrappingFunction	Callback to create a VirtualNode that wraps a given NodeInfo

Class Summary

Class	Description
AbstractNodeWrapper	A node in the XML parse tree representing an XML element, character content, or attribute.
AbstractVirtualNode	AbstractVirtualNode is an abstract superclass for VirtualNode implementations in which the underlying node is itself a Saxon NodeInfo.
SnapshotNode	This class represents a node within a tree produced by the snapshot() function, as a virtual copy of the relevant nodes in another tree.
SpaceStrippedDocument	A SpaceStrippedDocument represents a view of a real Document in which selected whitespace text nodes are treated as having been stripped.
SpaceStrippedNode	A StrippedNode is a view of a node, in a virtual tree that has whitespace text nodes stripped from it.
TypeStrippedDocument	A TypeStrippedDocument represents a view of a real Document in which all nodes are untyped
TypeStrippedNode	A TypeStrippedNode is a view of a node, in a virtual tree that has type annotations stripped from it.
VirtualCopy	This class represents a node that is a virtual copy of another node: that is, it behaves as a node that's the same as another node, but has different identity.
VirtualTreeInfo	Implementation of TreeInfo for a Virtual Copy tree
VirtualUntypedCopy	This class represents a virtual copy of a node with type annotations stripped
WrappingIterator	A WrappingIterator delivers wrappers for the nodes delivered by its underlying iterator.

Package net.sf.saxon.tree.wrapper Description

This package defines a number of implementations of "virtual nodes" implemented as wrappers around other nodes.

The SpaceStrippedNode class provides a virtual tree in which whitespace text nodes in the underlying real tree are ignored.

The TypeStrippedNode class provides a virtual tree in which type annotations in the underlying real tree are ignored.

The VirtualCopy class provides a tree that is the same as the underlying tree in everything except node identity.
