                                     boolean incremental,
                                     boolean doIndexing)

This method is copied from DTMManagerDefault in Xalan 2.5.1, in order to generate DOM2DTMEx objects for referent tracking purposes Get an instance of a DTM, loaded with the content from the specified source. If the unique flag is true, a new instance will always be returned. Otherwise it is up to the DTMManager to return a new instance or an instance that it already created and may be being used by someone else. A bit of magic in this implementation: If the source is null, unique is true, and incremental and doIndexing are both false, we return an instance of SAX2RTFDTM, which see. (I think more parameters will need to be added for error handling, and entity resolution, and more explicit control of the RTF situation).

Parameters:

source - the specification of the source object.

unique - true if the returned DTM must be unique, probably because it is going to be mutated.

whiteSpaceFilter - Enables filtering of whitespace nodes, and may be null.

incremental - true if the DTM should be built incrementally, if possible.

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

Returns:

a non-null DTM reference.
