Examples of com.atomikos.util.DynamicProxy

com.atomikos.util.DynamicProxy
An interface to improve performance of dynamic proxies. The added method 'getInvocationHandler' avoids calls to the Proxy class (which suffers from performance issues related to synchronization overhead).

    CompositeTransaction current = tm.getCompositeTransaction();
    if ( ( current != null ) && ( current.getProperty ( TransactionManagerImp.JTA_PROPERTY_NAME) != null )) {
      synchronized (sessions) {
        for (int i=0; i<sessions.size() ;i++) {
          Session session = (Session) sessions.get(i);
          DynamicProxy dproxy = ( DynamicProxy ) session;
          AbstractJmsSessionProxy proxy = (AbstractJmsSessionProxy) dproxy.getInvocationHandler();
          
          //recycle if either inactive in this tx, OR if active (since a new session will be created anyway, and 
          //concurrent sessions are allowed on the same underlying connection!
          if ( proxy.isInactiveTransaction(current) || proxy.isInTransaction( current ) ) {
            if ( LOGGER.isInfoEnabled() ) LOGGER.logInfo ( this + ": recycling session " + proxy );
