question: public static EndpointEntry lookup ( Endpoint ep ) { synchronized ( endpointTable ) { EndpointEntry entry = endpointTable . get ( ep ) ; if ( entry == null ) { entry = new EndpointEntry ( ep ) ; endpointTable . put ( ep , entry ) ; if ( gcLatencyRequest == null ) { gcLatencyRequest = GC . requestLatency ( gcInterval ) ; } } return entry ; } }
target:  Look up the EndpointEntry for the given Endpoint.  An entry is created if one does not already exist.
