Class DTMDefaultBaseTraversers

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.
Constructor Summary
DTMDefaultBaseTraversers(DTMManager mgr, Source source, int dtmIdentity, DTMWSFilter whiteSpaceFilter, XMLStringFactory xstringfactory, boolean doIndexing)
Construct a DTMDefaultBaseTraversers object from a DOM node.
DTMDefaultBaseTraversers(DTMManager mgr, Source source, int dtmIdentity, DTMWSFilter whiteSpaceFilter, XMLStringFactory xstringfactory, boolean doIndexing, int blocksize, boolean usePrevsib, boolean newNameTable)
Construct a DTMDefaultBaseTraversers object from a DOM node.
Method Summary
DTMAxisTraversergetAxisTraverser(int axis)
This returns a stateless "traverser", that can navigate over an XPath axis, though perhaps not in document order.

Constructor Detail

DTMDefaultBaseTraversers

public DTMDefaultBaseTraversers(DTMManager mgr, Source source, int dtmIdentity, DTMWSFilter whiteSpaceFilter, XMLStringFactory xstringfactory, boolean doIndexing)
Construct a DTMDefaultBaseTraversers object from a DOM node.

Parameters: mgr The DTMManager who owns this DTM. 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.

DTMDefaultBaseTraversers

public DTMDefaultBaseTraversers(DTMManager mgr, Source source, int dtmIdentity, DTMWSFilter whiteSpaceFilter, XMLStringFactory xstringfactory, boolean doIndexing, int blocksize, boolean usePrevsib, boolean newNameTable)
Construct a DTMDefaultBaseTraversers object from a DOM node.

Parameters: mgr The DTMManager who owns this DTM. 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. newNameTable true if we want to use a new ExpandedNameTable for this DTM.

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.
