OSCresponder client side network responder

Register a function to be called upon receiving a specific command from a specific OSC address.

Other applications sending messages to SuperCollider should distinguish between sending messages to the server or the language. Server messages are documented in the Server-Command-Reference and should be sent to the server's port - s.addr.port - which is 57110 by default. Messages sent to the server will not be processed by any OSCresponder in the language.

Messages from external clients that should be processed by OSCresponders must be sent to the language port, 57120 by default. Use NetAddr.langPort to confirm which port the SuperCollider language is listening on.

See OSC_communication for more details.

Important: It is highly recommended to use OSCresponderNode or OSCpathResponder instead of OSCresponder directly. OSCresponders can overwrite each other, but OSCresponderNodes with the same address and command name can coexist peacefully.

Examples: see OSCresponderNode

*new(addr, cmdName, action);

addr

the address the responder receives from (an instance of NetAddr, e.g. Server.default.addr)

an address of nil will respond to messages from anywhere.

an address with a port of nil will respond to messages from any port from that specific IP.

cmdName

an OSC command eg. '/done'

action

a function that will be evaluated when a cmd of that name is received from addr.

arguments: time, theResponder, message, addr

note that OSCresponder evaluates its function in the system process.

in order to access the application process (e.g. for GUI access ) use { ... }.defer;

within the action function, e.g., { |time, resp, msg| { gui.value_(msg[3]) }.defer }

Note:

A single OSCresponder may be set up for each addr and cmdName combination.

Subsequent registrations will overwrite previous ones. See OSCresponderNode.

Whenever an OSC message is sent to the SuperCollider application (the language, not the server), either Main-recvOSCmessage or Main-recvOSCbundle is called. There, the messages are forwarded to the OSCresponder class using the OSCresponder-respond class method.

add

add this responder instance to the list of active responders.

The OSCresponder is not active until this is done.

remove

remove and deactivate the OSCresponder

removeWhenDone

remove and deactivate the OSCresponder when action is done.

//syntax:

OSCresponder(addr,cmdName,action).add.removeWhenDone;

*add(oscResponder)

add the responder instance

*remove(oscResponder)

remove the responder instance

*removeAddr(addr)

remove all OSCresponders for that addr.
