Normally users should not have to create or message instances of this class directly. @section{CLASSMETHODS} @section{INSTANCEMETHODS} @section{METHOD} getKeysForFuncProxy Get the keys at which a responder func's functions are stored in this dispatcher's active dictionary. The keys will be MIDI channels. @section{argument} funcProxy The link::Classes/MIDIFunc:: or link::Classes/MIDIdef:: whose keys should be returned. @section{returns} An link::Classes/Array:: containing the funcProxy's channel number as an link::Classes/Integer::. @section{METHOD} value Attempt to match an incoming MIDI message with this dispatcher's responder funcs, and evaluate their functions for all matches found. @section{argument} src The UID of the source of the MIDI message as an link::Classes/Integer::. @section{argument} chan The channel number of the MIDI message as an link::Classes/Integer::. Note this should be in the range 0-15. @section{argument} val The message value (e.g. velocity, etc.) of the MIDI message as an link::Classes/Integer::. Note this should be in the range 0-127. @section{METHOD} wrapFunc Called internally to wrap functions in message matcher objects, if needed. @section{argument} funcProxy An instance of link::Classes/MIDIFunc:: or link::Classes/MIDIdef:: whose function(s) are to be wrapped.
