class:: UnaryOpUGen
summary:: Apply a unary operation to the values of an input ugen
categories:: UGens>Algebraic
related:: Classes/BinaryOpUGen, Classes/UnaryOpFunction, Classes/Punop, Overviews/Operators
description::
UnaryOpUGens are created as the result of a unary operator applied to a link::Classes/UGen::.
code::
(SinOsc.ar(200).abs).dump;
(LFSaw.ar(200).sin).dump;
::
As in the examples given here, you don't usually need to instantiate UnaryOpUGen yourself.
The unary and binary operators are defined in link::Classes/UGen::'s superclass link::Classes/AbstractFunction::, which creates the
BinaryOpUGen as a result of the operation.
See link::Overviews/Operators:: for an overview of common operators.
classmethods::
method::new
return a new instance that applies the operator code::selector:: to the ugen code::a::
argument:: selector
The selector symbol for the unary operator
argument:: a
operand
examples::
code::
a = WhiteNoise.ar; // a WhiteNoise
b = a.squared; // a UnaryOpUGen.
b.operator; // squared
// sound example
{ var a = LFSaw.ar(300).range(0, 2pi); a.sin * 0.1 }.play;
// Plotting the "abs" unary operator (via the server):
{ SinOsc.ar(300).abs }.plot
