Enclosing class:

protected static enum WsFrameBase.ReadState
extends Enum<WsFrameBase.ReadState>

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
