Subject Threading questions
Date Wed, 19 May 2004 17:19:05 GMT

I'm trying to understand what threads are doing what in Batik
when using JSVGCanvas and have some basic questions...

  - When manipulating the DOM, the UpdateManager's thread must be used.
    Are listeners are notified by the same thread in which the actual
    manipulation is done? So the next manipulation in the run queue
    does not happen until all listeners are notified of the previous

  - When many changes to the DOM are made in rapid succession, can
    the re-rendering process get arbitrarily far behind? Or does it
    know how to interrupt and restart itslef as soon as a new change
    is made?

Has anyone had to do manual "buffering" of DOM changes to avoid
the rendering getting to far behind?
