PstepNfunc

combinatoric pattern
Inherits from: Pattern : AbstractFunction : Object
Subclasses: PstepNadd

Description

Combines an arbitrary number of patterns by evaluating a function (depth first traversal). When a stream ends it is recreated from its pattern until the top stream ends.

Examples

(
f = { arg vals;
    vals.postln;
};
x = PstepNfunc(f, [
        Pseq([1, 2, 3]), Pseq([4, 5, 6]), Pseq([7, 8, 9])
    ]).asStream;
50.do({ x.next });
)

(
f = { arg vals;
    var r;
    r = vals.copy.removeAt(0);
    vals.do({ arg item;  r = item / r.squared * 10 });
    r
};
x = PstepNfunc(f,
    [
        Pseq([1, 2, 3], inf),
        Pseq([2, pi, 1]),
        Pseq([0.1, 3, 0.2, 3])
    ]
    ).asStream;

50.do({ x.next.postln });
)

// note that if the last pattern loops it will stick to that one:
(
f = { arg vals;
    vals.postln;
};
x = PstepNfunc(f, [Pseq([1, 2, 3]), Pseq([10, 20, 30, 40]), Pseq([100, 200, 300], inf)]).asStream;
50.do({ x.next });
)


(
f = { arg vals;
    vals.inject(1, { arg x, y; x * y })
};
x = PstepNfunc(f,
    [
        Pseq([1, 2, 3], inf),
        Pseq([2, pi, 1]),
        Pseq([0.1, 3, 0.2, 3])
    ]
    ).asStream;

50.do({ x.next.postln });
