Something like this should work:
JCas jcas1 = …
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
ObjectOutputStream docOS = new ObjectOutputStream(buffer);
CASCompleteSerializer serializerOut =
Serialization.serializeCASComplete(jcas1.getCasImpl());
docOS.writeObject(serializerOut);
docOS.close();
JCas jcas2 = …
ObjectInputStream is = new ObjectInputStream(new
ByteArrayInputStream(buffer.toByteArray()));
CASCompleteSerializer serializerIn = (CASCompleteSerializer) is.readObject();
Serialization.deserializeCASComplete(serializerIn, (CASImpl)
jcas2.getCasImpl());
You could try without the buffer and just passing the seralizerOut as
serializerIn, but I don't
know if that works because I don't know if the internal data structures are
copied to the target
CAS or if they are directly injected.
