------------------------------------------------
Summary: Constructing aggregate engines is slow
Key: UIMA-6200
URL: https://issues.apache.org/jira/browse/UIMA-6200
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Reporter: Richard Eckart de Castilho
Fix For: 2.10.5SDK
Attachments: Screenshot 2020-03-15 at 18.50.30.png
Creating an aggregate engine is slow because every time a default fixed flow
descriptor is loaded from the classpath as XML and parsed.
*FixedFlowController*
{code}
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;
}
{code}
IMHO, this should be loaded once and then cached permanently - or be
constructed completely programmatically (also once!) and never loaded at all.
