/*! \class Messager
|
||||
\brief STK input control message parser.
|
||||
|
||||
This class reads and parses control messages
|
||||
from a variety of sources, such as a MIDI
|
||||
port, scorefile, socket connection, or pipe.
|
||||
MIDI messages are retrieved using the RtMidi
|
||||
class. All other input sources (scorefile,
|
||||
socket, or pipe) are assumed to provide SKINI
|
||||
formatted messages.
|
||||
|
||||
For each call to nextMessage(), the active
|
||||
input sources are queried to see if a new
|
||||
control message is available.
|
||||
|
||||
This class is primarily for use in STK main()
|
||||
event loops.
|
||||
|
||||
One of the original goals in creating this
|
||||
class was to simplify the message acquisition
|
||||
process by removing all threads. If the
|
||||
windoze select() function behaved just like
|
||||
the unix one, that would have been possible.
|
||||
Since it does not (it can't be used to poll
|
||||
STDIN), I am using a thread to acquire
|
||||
messages from STDIN, which sends these
|
||||
messages via a socket connection to the
|
||||
message socket server. Perhaps in the future,
|
||||
it will be possible to simplify things.
