Package net.sf.saxon.tree.util

This package defines a number of utility and helper classes for implementing tree models.

See: Description

Interface Summary

Interface	Description
SteppingNode<N extends SteppingNode>	This interface can be implemented by an implementation of NodeInfo to take advantage of a generic implementation of the descendant axis found in class SteppingNavigator

Class Summary

Class	Description
AttributeCollectionImpl	AttributeCollectionImpl is an implementation of both the SAX2 interface Attributes and the Saxon equivalent AttributeCollection.
DocumentNumberAllocator	This class (which has one instance per Configuration) is used to allocate unique document numbers.
FastStringBuffer	A simple implementation of a class similar to StringBuffer.
NamespaceIterator	This class provides an iterator over the namespace codes representing the in-scope namespaces of any node.
NamespaceResolverWithDefault	This class is a NamespaceResolver that modifies an underyling NamespaceResolver by changing the mapping of the null prefix to be a specified namespace, rather than the one used by the underlying namespace resolver.
Navigator	The Navigator class provides helper classes for navigating a tree, irrespective of its implementation
Navigator.AncestorEnumeration	General-purpose implementation of the ancestor and ancestor-or-self axes
Navigator.AxisFilter	AxisFilter is an iterator that applies a NodeTest filter to the nodes returned by an underlying AxisIterator.
Navigator.DescendantEnumeration	General-purpose implementation of the descendant and descendant-or-self axes, in terms of the child axis.
Navigator.EmptyTextFilter	EmptyTextFilter is an iterator that applies removes any zero-length text nodes returned by an underlying AxisIterator.
Navigator.FollowingEnumeration	General purpose implementation of the following axis, in terms of the ancestor, child, and following-sibling axes
Navigator.PrecedingEnumeration	Helper method to iterate over the preceding axis, or Saxon's internal preceding-or-ancestor axis, by making use of the ancestor, descendant, and preceding-sibling axes.
Orphan	A node (implementing the NodeInfo interface) representing an attribute, text node, comment, processing instruction, or namespace that has no parent (and of course no children).
ProcInstParser	ProcInstParser is used to parse pseudo-attributes within Processing Instructions.
SteppingNavigator	The SteppingNavigator is a utility class containing methods to assist with navigating a tree whose nodes implement the SteppingNode interface
SteppingNavigator.DescendantAxisIterator<N extends SteppingNode<N>>	An iterator over the descendant or descendant-or-self axis

Package net.sf.saxon.tree.util Description

This package defines a number of utility and helper classes for implementing tree models.

The Navigator class provides many utility methods, for example to implement various axes in terms of other axes, and to support numbering.

The Orphan class is a general-purpose implementation of a node with no parent, no attributes, and no children.
