Examples with SessionListener org.apache.stanbol.ontologymanager.servicesapi.session.SessionListener used on opensource projects

Example 1 with SessionListener

use of org.apache.stanbol.ontologymanager.servicesapi.session.SessionListener in project stanbol by apache.

the class SessionManagerImpl method createSession.

         * Throw the duplicate ID exception first, in case developers decide to reuse the existing session
         * before creating a new one.

    if (ontologyProvider instanceof SessionListener)
        session.addSessionListener((SessionListener) ontologyProvider);
    Multiplexer multiplexer = ontologyProvider.getOntologyNetworkDescriptor();
    session.addOntologyCollectorListener(multiplexer);

Example 2 with SessionListener
