Examples of 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).

Examples of com.atomikos.util.DynamicProxy

  public boolean isAvailable() {
    boolean ret = true;


    Reapable handle = getCurrentConnectionProxy();
    if ( handle != null ) {
      DynamicProxy dproxy = ( DynamicProxy ) handle;
      AtomikosThreadLocalConnection previous = (AtomikosThreadLocalConnection) dproxy.getInvocationHandler();
      ret = previous.isNoLongerInUse();
    }
    
    return ret;
