@section{description}
AbstractResponderFunc is the abstract superclass of responder funcs, which are classes which register one or more functions to respond to a particular type of input. It provides some common functionality such as introspection. Its two main subclasses are link::Classes/OSCFunc::, and link::Classes/MIDIFunc::. By default responder funcs do not persist beyond Cmd-. (see link::#-permanent:: below).
Instances will register with a dispatcher (an instance of a subclass of link::Classes/AbstractDispatcher::), which will actually dispatch incoming messages to an instance's Function(s).
@section{CLASSMETHODS}
@section{private}
initClass
@section{METHOD}
allFuncProxies
Get all current instances of this classes concrete subclasses, sorted by type.
@section{returns}
An link::Classes/IdentityDictionary::.
@section{METHOD}
allEnabled
As allFuncProxies above, but only return those instances currently listening for input.
@section{returns}
An link::Classes/IdentityDictionary::.
@section{METHOD}
allDisabled
As allFuncProxies above, but only return those instances currently not listening for input.
@section{returns}
An link::Classes/IdentityDictionary::.
@section{INSTANCEMETHODS}
@section{private}
cmdPeriod, prFunc
@section{METHOD}
func
Get or set this objects response function.
@section{returns}
The getter returns a link::Classes/Function:: or similar object.
@section{METHOD}
srcID
Get this object's source.
@section{returns}
The return type will depend on subclass. For link::Classes/OSCFunc:: this will be a link::Classes/NetAddr::, for link::Classes/MIDIFunc:: a UID. This can can be nil, which indicates that the object will respond to any source.
@section{METHOD}
enabled
Check if this object is currently responding to incoming messages.
@section{returns}
A link::Classes/Boolean::.
@section{METHOD}
dispatcher
et this object's dispatcher. This is the object which matches incoming messages with responder funcs. Instances can use custom dispatchers to support arbitrary matching schemes.
@section{returns}
An instance of an appropriate subclass of link::Classes/AbstractDispatcher::. (The return type will depend on subclass.)
@section{METHOD}
permanent
Get or set whether this responder func is persists when the user executes Cmd-. If false this will be disabled and removed from the global lists. The default is false.
@section{argument}
bool
A link::Classes/Boolean:: indicating if this object is permanent.
@section{returns}
The getter returns a link::Classes/Boolean::.
@section{METHOD}
enable
Enable this object to receive incoming messages. This is done automatically at creation time.
@section{METHOD}
disable
Stop this object from receiving incoming messages.
@section{METHOD}
add
Add a new function to the list of functions which will be executed when this object receives an incoming message.
@section{argument}
newFunc
A link::Classes/Function:: or similar object to be added.
@section{METHOD}
remove
Remove a function from the list of functions which will be executed when this object receives an incoming message.
@section{argument}
removeFunc
The link::Classes/Function:: to be removed.
@section{METHOD}
gui
Open a subclass specific GUI. (Not yet implemented)
@section{returns}
The GUI object.
@section{METHOD}
oneShot
Indicate that this object should execute only once and then free itself.
@section{METHOD}
fix
A synonym for link::#permanent::
@section{METHOD}
free
Disable this object and remove it from the global lists. This should be done when you are finished using this object.
@section{METHOD}
clear
Remove all active functions from this object's function list.
@section{EXAMPLES}
See link::Classes/OSCFunc:: and link::Classes/MIDIFunc::.
