Examples of org.drools.marshalling.Marshaller.unmarshall()

org.drools.marshalling.Marshaller.unmarshall()
Creates StatefulKnowledgeSession using default KnowledgeSessionConfiguration and Environment. It will then unmarshall the stream into the session. Either KnowledgeSessionConfiguration or Environment may be null and it will use the default. @param stream @return @throws IOException @throws ClassNotFoundException

        // Unmarshall
        StatefulKnowledgeSession ksession = marshaller.unmarshall( bais, conf, env );
