Class NodeSequence

public class NodeSequence extends XObject implements DTMIterator, Cloneable, PathComponent

This class is the dynamic wrapper for a Xalan DTMIterator instance, and provides random access capabilities.

Constructor Summary
	NodeSequence(DTMIterator iter, int context, XPathContext xctxt, boolean shouldCacheNodes) Create a new NodeSequence from a (already cloned) iterator.
	NodeSequence(Object nodeVector) Create a new NodeSequence from a (already cloned) iterator.
	NodeSequence(DTMManager dtmMgr) Construct an empty XNodeSet object.
	NodeSequence() Create a new NodeSequence in an invalid (null) state.

Method Summary
void	allowDetachToRelease(boolean allowRelease) Calling this with a value of false will cause the nodeset to be cached.
Object	clone() Get a clone of this iterator, but don't reset the iteration in the process, so that it may be used from the current position.
DTMIterator	cloneWithReset() Note: Not a deep clone.
void	detach()
void	fixupVariables(Vector vars, int globalsSize)
int	getAnalysisBits()
int	getAxis()
DTMIterator	getContainedIter() Get the functional iterator that fetches nodes.

Constructor Detail

NodeSequence

public NodeSequence(DTMIterator iter, int context, XPathContext xctxt, boolean shouldCacheNodes)

Create a new NodeSequence from a (already cloned) iterator.

Parameters: iter Cloned (not static) DTMIterator. context The initial context node. xctxt The execution context. shouldCacheNodes True if this sequence can random access.
