info(StreamID, Info, State) -> {Commands, State} StreamID :: cowboy_stream:stream_id() Info :: any() Commands :: cowboy_stream:commands() State - opaque
Handle a message for a stream.
This function should be called by all stream handlers. It will propagate the event to the next configured stream handler. Handlers do not have to propagate events that have been fully handled.
The stream ID.
The event received.
The commands to be executed.
The state for the next stream handler.
A list of commands and an opaque state is returned.
The list of commands returned should be included in the commands returned from the current stream handler. It can be modified if necessary.
The state should be stored in the current stream handler's state and passed to cowboy_stream
when necessary. The state should be treated as opaque.
info(StreamID, Info, State=#state{next=Next0}) -> MyCommands = my_commands(), {Commands, Next} = cowboy_stream:info(StreamID, Info, Next0), {MyCommands ++ Commands, #state{next=Next}}.
