## org.apache.xml.dtm.ref
Class DTMDefaultBaseTraversers

    java.lang.Object
      org.apache.xml.dtm.ref.DTMDefaultBase
          org.apache.xml.dtm.ref.DTMDefaultBaseTraversers

All Implemented Interfaces:
  DTM

Direct Known Subclasses:
  DTMDefaultBaseIterators

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

    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.
