    - #### EVENTTYPE_STARTELEMENT

          static final int EVENTTYPE_STARTELEMENT

      Event type generated when an element begins (after the attributes have been processed but before the children have been added).
      See Also:
        Constant Field Values

    - #### EVENTTYPE_ENDELEMENT

          static final int EVENTTYPE_ENDELEMENT

      Event type generated when an element ends, after it's children have been added.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_CHARACTERS

          static final int EVENTTYPE_CHARACTERS

      Event type generated for character data (CDATA and Ignorable Whitespace have their own events).
      See Also:
        Constant Field Values

    - #### EVENTTYPE_IGNORABLEWHITESPACE

          static final int EVENTTYPE_IGNORABLEWHITESPACE

      Event type generated for ignorable whitespace (I'm not sure how much this is actually called.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_PI

          static final int EVENTTYPE_PI

      Event type generated for processing instructions.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_COMMENT

          static final int EVENTTYPE_COMMENT

      Event type generated after a comment has been added.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_ENTITYREF

          static final int EVENTTYPE_ENTITYREF

      Event type generate after an entity ref is created.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_CDATA

          static final int EVENTTYPE_CDATA

      Event type generated after CDATA is generated.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS

          static final int EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS

      Event type generated when characters might be written to an output stream, but these characters never are. They will ultimately be written out via EVENTTYPE_OUTPUT_CHARACTERS. This type is used as attributes are collected. Whenever the attributes change this event type is fired. At the very end however, when the attributes do not change anymore and are going to be ouput to the document the real characters will be written out using the EVENTTYPE_OUTPUT_CHARACTERS.
      See Also:
        Constant Field Values

    - #### EVENTTYPE_OUTPUT_CHARACTERS

          static final int EVENTTYPE_OUTPUT_CHARACTERS
