Example 2 with SAXNotRecognizedException

use of org.xml.sax.SAXNotRecognizedException in project j2objc by google.

the class DTMManagerDefault method getDTM.

/**
   * 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).
   *
   * @param source the specification of the source object.
   * @param unique true if the returned DTM must be unique, probably because it
   * is going to be mutated.
   * @param whiteSpaceFilter Enables filtering of whitespace nodes, and may
   *                         be null.
   * @param incremental true if the DTM should be built incrementally, if
   *                    possible.
   * @param doIndexing true if the caller considers it worth it to use
   *                   indexing schemes.
   *
   * @return a non-null DTM reference.
