Constructing aggregate engines is slow

    XMLWordPrintableJSON

    Details

      Description

      Creating an aggregate engine is slow because every time a default fixed flow descriptor is loaded from the classpath as XML and parsed.

      FixedFlowController

        public static FlowControllerDescription getDescription() {
          URL descUrl = FixedFlowController.class
                  .getResource("/org/apache/uima/flow/FixedFlowController.xml");
          FlowControllerDescription desc;
          try {
            desc = (FlowControllerDescription) UIMAFramework.getXMLParser().parse(
                    new XMLInputSource(descUrl));
          } catch (InvalidXMLException e) {
            throw new UIMARuntimeException(e);
          } catch (IOException e) {
            throw new UIMARuntimeException(e);
          }
          return desc;
        }
      

      IMHO, this should be loaded once and then cached permanently - or be constructed completely programmatically (also once!) and never loaded at all.
