Class Methods

Condition.new(test: false)

Create a new instance, set the test variable.

Instance Methods

.test = value

Answer whether the condition will block or not (boolean).

Wait until the condition is true and signalled. This only works in a Routine. This method yields a symbol (\hang), so that the clock doesn't reschedule the Routine.c = Condition(false); fork { 0.5.wait; "started ...".postln; c.wait; "... and finished.".postln }; c.test = true; c.signal;

.hang(value: 'hang')

Wait for value time, regardless of test. This only works in a Routine. This method yields a symbol (\hang), so that the clock doesn't reschedule the Routine.c = Condition.new; fork { 0.5.wait; "started ...".postln; c.hang; "... and finished.".postln }; c.unhang;

.signal

If -test is true, reschedule blocked threads.

.unhang

Resume threads.

Examples

Waiting for Synths to end (waitForFree) uses a Condition implicitly:( SynthDef(\help, { |out| var mod = LFNoise2.kr(ExpRand(0.5, 2)) * 0.5; var snd = mod * Blip.ar(Rand(200, 800) * (mod + 1)); Out.ar(out, snd); FreeSelf.kr(mod < 0); // free the synth when amplitude goes below 0. }).add; ) ( fork { 10.do { "started a synth".postln; Synth(\help).waitForFree; "This one ended. Wait a second, I will start the next one.".postln; 1.wait; }; "This is it.".postln; } );
