Interrupting transform

Added by Anonymous almost 15 years ago

Hi everyone, is there a standard way to (Thread.)interrupt a running transform? I am running .transform within a thread of its own. Now I like to "kill" the thread. As Thread.stop is deprecated I have to use Thread.interrupt() which only works if the interrrupted thread cooperates. Is there a standard way to check for the interrupt flag of the thread running the transform? Is there alread a checked interrupt flag in saxon? Right now, we are thinking in implementing a kind of listener/handler that receives callbacks from transform, checks the interrupt flag and throws a TransformationException to abort the transform. Any help is appreciated. Thanks Oliver

No, there's no standard or recommended way to do this, you'll have to devise your own. Some debugging environments use a TraceListener, but that significantly reduces performance because it disables a number of optimisations (also, if a long time is spent in path expressions searching a large document, there can be a significant time elapsed between calls). You can also intercept output written to the serializer or result tree, but again there can be a long time between calls.
