Hi Artem, did you try asking the AggregateBuilder for a description, calling getOperationalProperties().setOutputsNewCASes(true) on the description and then creating the engine?
I have an apparently working piece of code looking along these lines // The part starting with a splitter and ending with a merger has to be in its own // aggregate. The flow controller of the aggregate has to drop the intermediate CASes. FlowControllerDescription fcd = createFlowControllerDescription(FixedFlowController.class, FixedFlowController.PARAM_ACTION_AFTER_CAS_MULTIPLIER, "drop"); AnalysisEngineDescription embedded = createEngineDescription(fcd, splitter, tokenizer, merger); // The final merged CAS, however, needs to be returned from the aggregate embedded.getAnalysisEngineMetaData().getOperationalProperties().setOutputsNewCASes(true); // Need to wrap into another aggregate because runPipeline has no immediate support for // flow control AnalysisEngineDescription pipelineDesc = createEngineDescription(sentenceDetector, embedded, consumer); SimplePipeline.runPipeline(createReaderDescription(…), pipelineDesc); Cheers, -- Richard On 30.08.2013, at 23:32, Artem Vovk <[email protected]> wrote: > Hi, > > I wanted to write a test for MyJCasMultiplier, to check how many JCases are > created.
