  • Constructor Details

    • DTMDefaultBaseIterators

      public DTMDefaultBaseIterators(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.
    • DTMDefaultBaseIterators

      public DTMDefaultBaseIterators(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.

    • getTypedAxisIterator

      public DTMAxisIterator getTypedAxisIterator(int axis, int type)
      Get an iterator that can navigate over an XPath Axis, predicated by the extended type ID. Returns an iterator that must be initialized with a start node (using iterator.setStartNode()).
      Parameters:
      axis - One of Axes.ANCESTORORSELF, etc.
      type - An extended type ID.
      Returns:
      A DTMAxisIterator, or null if the given axis isn't supported.
    • getAxisIterator

      public DTMAxisIterator getAxisIterator(int axis)
      This is a shortcut to the iterators that implement the XPath axes. Returns a bare-bones iterator that must be initialized with a start node (using iterator.setStartNode()).
      Parameters:
      axis - One of Axes.ANCESTORORSELF, etc.
      Returns:
      A DTMAxisIterator, or null if the given axis isn't supported.
