Hi,
I am developing an NLP tool based on latest UIMA version (2.3.0
incubating). Basically, the tool utilizes an aggregate engine with
several primitive engines.
Currently, I am having a problem with the handling of ByteArray values
of one of the annotation features.
Here is how am I setting the value of the feature:
final ByteArray ba = new ByteArray(
cas, wordHypernymsAsBytes.length );
ba.copyFromArray( wordHypernymsAsBytes,
0, 0, wordHypernymsAsBytes.length );
token.setHypernyms( ba );
And here is how am I reading the ByteArray features (there will be more,
so I need a generic way of reading them):
List< Feature > annoFeatures =
anno.getCAS().getJCas().getTypeSystem().getType(
anno.getType().getName() ).getFeatures();
Iterator< Feature > featIter = annoFeatures.iterator();
....
while ( featIter.hasNext() ) {
Feature feature = featIter.next();
...
if ( feature.getRange().getName().equalsIgnoreCase(
"uima.cas.ByteArray" ) ) {
FeatureStructure fs = anno.getFeatureValue( feature );
if ( fs != null ) {
byte[] bytes = ( ( ByteArrayFS ) fs ).toArray();
----> here is the problem actually. The bytes array contains a single
byte (length of the array is 1). The "setter" above is setting something
much longer.
}
}
}
My question is how to read&write the ByteArray features?
Attached you can find the serialized CAS file as well...
greetings
Diman
