related:: Classes/Pfuncn
description::
Returns a link::Classes/Stream:: that returns values from the code::nextFunc::.
classmethods::
method:: new
argument:: nextFunc
Stream function. In an event stream receives the current link::Classes/Event:: as argument.
argument:: resetFunc
Function that is called when the stream is reset. In an event stream receives the current link::Classes/Event:: as argument.
examples::
code::
(
var a, x;
a = Pfunc({ exprand(0.1, 2.0) + #[1, 2, 3, 6].choose }, { \reset.postln });
x = a.asStream;
x.nextN(20).postln;
x.reset;
