connectionIdThe connectionID that received the event.
channelIdThe channel ID associated with the event.
bufferThe buffer that will hold the data received.
bufferSizeSize of the buffer supplied.
receivedSizeThe actual receive size of the data.
errorError (can be cast to NetworkError for more information).

Returns

NetworkEventType Type of event returned.
