public abstract class DTMDefaultBaseTraversers

extends DTMDefaultBase

This class implements the traversers for DTMDefaultBase. PLEASE NOTE that the public interface for all traversers should be in terms of DTM Node Handles... but they may use the internal node identity indices within their logic, for efficiency's sake. Be very careful to avoid confusing these when maintaining this code.

Method Summary

DTMAxisTraverser

getAxisTraverser(int axis) This returns a stateless "traverser", that can navigate over an XPath axis, though perhaps not in document order.

DTMDefaultBaseTraversers

public DTMDefaultBaseTraversers(DTMManager mgr,
                                Source source,
                                int dtmIdentity,
                                DTMWSFilter whiteSpaceFilter,

                                boolean doIndexing)

Construct a DTMDefaultBaseTraversers object from a DOM node.

Parameters:

mgr - The DTMManager who owns this DTM.

domSource - the DOM source that this DTM will wrap.

source - The object that is used to specify the construction source.

dtmIdentity - The DTM identity ID for this DTM.

whiteSpaceFilter - The white space filter for this DTM, which may be null.

xstringfactory - The factory to use for creating XMLStrings.

doIndexing - true if the caller considers it worth it to use indexing schemes.

                                boolean usePrevsib)

Construct a DTMDefaultBaseTraversers object from a DOM node.

Parameters:

mgr - The DTMManager who owns this DTM.

domSource - the DOM source that this DTM will wrap.

source - The object that is used to specify the construction source.

dtmIdentity - The DTM identity ID for this DTM.

whiteSpaceFilter - The white space filter for this DTM, which may be null.

xstringfactory - The factory to use for creating XMLStrings.

doIndexing - true if the caller considers it worth it to use indexing schemes.

blocksize - The block size of the DTM.

usePrevsib - true if we want to build the previous sibling node array.

Method Detail

getAxisTraverser

public DTMAxisTraverser getAxisTraverser(int axis)

This returns a stateless "traverser", that can navigate over an XPath axis, though perhaps not in document order.

Parameters:

axis - One of Axes.ANCESTORORSELF, etc.

Returns:

A DTMAxisTraverser, or null if the given axis isn't supported.
