Member Function Documentation

void inet::SCTPSocketMap::addSocket

(

SCTPSocket *

socket

)

Registers the given socket.

Should not be called multiple times for one socket object.

{
    ASSERT(socketMap.find(socket->getConnectionId()) == socketMap.end());
    socketMap[socket->getConnectionId()] = socket;
}

void inet::SCTPSocketMap::deleteSockets

(

)

Deletes the socket objects.

{
    for (auto & elem : socketMap)
        delete elem.second;
    socketMap.clear();
}

SCTPSocket * inet::SCTPSocketMap::findSocketFor

(

cMessage *

msg

)

Finds the socket (by connId) for the given message.

The message must have arrived from SCTP, and must contain a SCTPCommand control info object. The method returns nullptr if the socket was not found, and throws an error if the message doesn't contain a SCTPCommand.

{
    SCTPCommand *ind = dynamic_cast<SCTPCommand *>(msg->getControlInfo());
    if (!ind)
        throw cRuntimeError("SCTPSocketMap: findSocketFor(): no SCTPCommand control info in message (not from SCTP?)");

    for (auto & elem : socketMap) {
        if (elem.second->belongsToSocket(msg)) {
            return elem.second;
        }
    }
    return nullptr;
}

SCTPSocket * inet::SCTPSocketMap::removeSocket

(

SCTPSocket *

socket

)

Removes the given socket from the data structure.

{
    auto i = socketMap.find(socket->getConnectionId());
    if (i != socketMap.end())
        socketMap.erase(i);
    return socket;
}

unsigned int inet::SCTPSocketMap::size ( )

inline

Returns the number of sockets stored.

{ return socketMap.size(); }
