WAITING - not suspended Server case: waiting for a notification that data is ready to be read from the socket, the socket is registered to the poller Client case: data has been read from the socket and is waiting for data to be processed PROCESSING - not suspended Server case: reading from the socket and processing the data Client case: processing the data if such has already been read and more data will be read from the socket SUSPENDING_WAIT - suspended, a call to suspend() was made while in WAITING state. A call to resume() will do nothing and will transition to WAITING state SUSPENDING_PROCESS - suspended, a call to suspend() was made while in PROCESSING state. A call to resume() will do nothing and will transition to PROCESSING state SUSPENDED - suspended Server case: processing data finished (SUSPENDING_PROCESS) / a notification was received that data is ready to be read from the socket (SUSPENDING_WAIT), socket is not registered to the poller Client case: processing data finished (SUSPENDING_PROCESS) / data has been read from the socket and is available for processing (SUSPENDING_WAIT) A call to resume() will: Server case: register the socket to the poller Client case: resume data processing CLOSING - not suspended, a close will be sent resume data to be resume no action processed no action |---------------| |---------------| |----------| | v | v v | | |----------WAITING«--------PROCESSING----| | | | ^ processing | | | | | finished | | | | | | | | suspend | suspend | | | | | | | | resume | | | | register socket to poller (server) | | | | resume data processing (client) | | | | | | | | v | v | SUSPENDING_WAIT | SUSPENDING_PROCESS | | | | data available | processing finished | |-------------»SUSPENDED«----------------------|
