(default_in_port_class, default_out_port_class): New static variables,
replacing default_port_class. (all_connections_local_targets): New map table; not used yet, though. (debug_connection): Temporarily set to 1. ([Connection +initialize]): Set new static vars. ([Connection +setDefaultInPortClass:]): New method. ([Connection +defaultInPortClass]): New method. ([Connection +setDefaultOutPortClass:]): New method. ([Connection +defaultOutPortClass]): New method. ([Connection -init]): Use new default_in_port_class. ([Connection +new]): Likewise. ([Connection +newWithRootObject:]): Likewise. ([Connection +newRegisteringAtName:withRootObject:]): Likewise. ([Connection +rootProxyAtName:onHost:]): Likewise. ([Connection +rootProxyAtPort:]): Likewise. ([Connection +newForInPort:outPort:ancestorConnection:]): Assert the in port. Embellish the debugging message to print the in port and out port. Set the new connection's in port and out port ivars. Register ourselves as observers of port invalidation with the NotificationDispatcher. Post a notification that a new connection was created. ([Connection -runConnectionWithTimeout:]): Use _serviceReceivedRequestsWithTimeout:. ([Connection -_newReceivedRmcWithTimeout:]): Use decodingClass, not encodingClass. ([Connection -_serviceReceivedRequestsWithTimeout:]): Method name changed from -newReceivedReplyRmcWithSequenceNumber:. ([Connection +includesLocalObject:]): New method; still needs more infrastructure to work, though. ([Connection -inPortClass]): New method. ([Connection -outPortClass]): New method. ([Connection -setInPortClass:aPortClass]): New method. ([Connection -setOutPortClass:aPortClass]): New method. ([Connection -_encoderCreateReferenceForConstPtr:]): Add 1 to map table count to get xref. ([Connection -_decoderCreateReferenceForConstPtr:]): Likewise. ([Connection -dealloc]): Remove ourselves from the NotificationDispatcher. (ConnectionWasCreatedNotification): New notification string. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/base/trunk@1057 72102866-910b-0410-8b05-ffd578937521
