HI,
I am trying to use the CasCopier api to copy a cas into an other. I get a
Exception.
This is how I am Copying the CAS. next() is a method I am trying to
over-ride that is in the "CasMultiplier_ImplBase"
Can some one help me figure out my mistake, if any ? I pasted the code
snippet, and also the Exception from the console.
- Thanks
Harsha

public AbstractCas next() throws AnalysisEngineProcessException {
// myCas guaranteed not to be null
// while(myCas.getTypeSystem().getFeatures().hasNext()){
// System.out.println("myCas TS Feature :
"+myCas.getTypeSystem().getFeatures().next());
// }
CAS output = null;
if (counter < target) {
// copy myCas
output = getEmptyCAS();
CasCopier.copyCas(myCas, output, true);
counter += 1;
} else {
// release myCas
output = myCas;
myCas = null;
counter = 0;
}
// annotate indicator with integer value between 0 and count,
inclusive
// 0 represents the original CAS, 1 to count represent respectively
the
// 1st through count-th copy CASes released.
TypeSystem ts = output.getTypeSystem();
Type indicatorType = ts.getType(TRANSFER_TYPE);
Feature valueFeature =
indicatorType.getFeatureByBaseName(TRANSFER_FEATURE);
FeatureStructure indicator = output.createFS(indicatorType);
indicator.setIntValue(valueFeature, counter);
output.addFsToIndexes(indicator);
return output;
}
