Modifies each value by passing it to the function. This is the pattern library's equivalent of Collection: -collect.
(
a = Pcollect( { |item| item * 3 }, Pseq( #[ 1, 2, 3 ], inf ) );
x = a.asStream;
9.do( { x.next.postln; } );
)
The message collect returns a Pcollect when passed to a pattern. Note that because the pattern is converted to a Stream (more precisely a FuncStream) the collect function is evaluated for one item each time the message next is passed.
(
a = Pseq( #[ 1, 2, 3 ], inf ).collect( { arg item; item * 3 } );
a.postln;
x = a.asStream;
9.do( { x.next.postln; } );
)
