Array : ArrayedCollection : SequenceableCollection : Collection : Object

Create a new array with size 0 that can grow up to the fixed size.

Arguments:

Create a new array with all slots filled with nils.

Arguments:

Create a new Array whose slots are filled with the given arguments. This is the same as the method in ArrayedCollection, but is reimplemented here to be more efficient.Array.with(7, 'eight', 9).postln;

Creates a Collection of the given size, the elements of which are determined by evaluation the given function. The function is passed the index as an argument.Array.fill(4, { arg i; i * 2 }); Bag.fill(14, { arg i; i.rand });

Arguments:

Creates a 2 dimensional Collection of the given sizes. The items are determined by evaluation of the supplied function. The function is passed row and column indexes as arguments. See J concepts in SCArray.fill2D(2, 4, 0); Array.fill2D(3, 4, { arg r, c; r*c+c; });

Creates a N dimensional Collection where N is the size of the array dimensions. The items are determined by evaluation of the supplied function. The function is passed N number of indexes as arguments. See J concepts in SCArray.fillND([4, 4], { arg a, b; a+b; }); // 2D Array.fillND([4, 4, 4], { arg a, b, c; a+b*c; }); // 3D Array.fillND([1, 2, 3, 4], { arg a, b, c, d; b+d; }); // 4D

Creates a new Collection from another collection. This supports the interface for the method "as".Array.newFrom(Set[4, 2, 1]); Set.newFrom(Array[4, 2, 1]); [1, 2, 3, 4, 3, 2].as(Set); // as(someClass) calls someClass.newFrom(this)

Fill an ArrayedCollection with a geometric series.Array.geom(5, 1, 3).postln;

Fill an ArrayedCollection with an arithmetic series.Array.series(5, 10, 2).postln;

Fills an ArrayedCollection with a counter. See J concepts in SC for more examples.Array.iota(2, 3); Array.iota(2, 3, 4);

Fill a SequenceableCollection with the interpolated values between the start and end values.Array.interpolation(5, 3.2, 20.5);

Fill a SequenceableCollection with random values in the range minVal to maxVal.Array.rand(8, 1, 100);

Fill a SequenceableCollection with random values in the range -val to +val.Array.rand2(8, 100);

Fill a SequenceableCollection with random values in the range minVal to maxVal with exponential distribution.Array.exprand(8, 1, 100);

Fill a SequenceableCollection with a fibonacci series.Array.fib(5); Array.fib(5, 2, 32); // start from 32 with step 2.

Arguments:

Return the item at index.

The index can also be an Array of indices to extract specified elements. Example:x = [10,20,30]; y = [0,0,2,2,1]; x[y]; // returns [ 10, 10, 30, 30, 20 ]

Put item at index, replacing what is there.

Inserts the item into the contents of the receiver. This method may return a new ArrayedCollection. For this reason, you should always assign the result of insert to a variable - never depend on add changing the receiver.( // in this case a new object is returned var y, z; z = [1, 2, 3, 4]; y = z.insert(1, 999); z.postln; y.postln; )

Same as -at, but values for index greater than the size of the ArrayedCollection will be clipped to the last index.y = [ 1, 2, 3 ]; y.clipAt(13).postln;

Same as -at, but values for index greater than the size of the ArrayedCollection will be wrapped around to 0.y = [ 1, 2, 3 ]; y.wrapAt(3).postln; // this returns the value at index 0 y.wrapAt(4).postln; // this returns the value at index 1 y.wrapAt([-2, 1]) // index can also be a collection or negative numbers

Same as -at, but values for index greater than the size of the ArrayedCollection will be folded back.y = [ 1, 2, 3 ]; y.foldAt(3).postln; // this returns the value at index 1 y.foldAt(4).postln; // this returns the value at index 0 y.foldAt(5).postln; // this returns the value at index 1

Same as -put, but values for index greater than the size of the ArrayedCollection will be clipped to the last index.

Same as -put, but values for index greater than the size of the ArrayedCollection will be wrapped around to 0.

Same as -put, but values for index greater than the size of the ArrayedCollection will be folded back.

Swap the values at indices i and j.[ 1, 2, 3 ].swap(0, 2).postln;

Return a new array in which a number of elements have been replaced by another.a = (0..10) ++ (0..10); a.replace([4, 5, 6], 100); a.replace([4, 5, 6], [1734, 1985, 1860]);

this method is inherited by String :a = "hello world"; a.replace("world", "word");

Concatenate the contents of the two collections into a new ArrayedCollection.( var y, z; z = [1, 2, 3, 4]; y = z ++ [7, 8, 9]; z.postln; y.postln; )

Adds an item to an ArrayedCollection if there is space. This method may return a new ArrayedCollection. For this reason, you should always assign the result of add to a variable - never depend on add changing the receiver.( // z and y are the same object var y, z; z = [1, 2, 3]; y = z.add(4); z.postln; y.postln; ) ( // in this case a new object is returned var y, z; z = [1, 2, 3, 4]; y = z.add(5); z.postln; y.postln; )

Adds all the elements of aCollection to the contents of the receiver. This method may return a new ArrayedCollection. For this reason, you should always assign the result of addAll to a variable - never depend on add changing the receiver.( // in this case a new object is returned var y, z; z = [1, 2, 3, 4]; y = z.addAll([7, 8, 9]); z.postln; y.postln; )

Inserts the item before the contents of the receiver, possibly returning a new collection.( // in this case a new object is returned var y, z; z = [1, 2, 3, 4]; y = z.addFirst(999); z.postln; y.postln; )

Remove and return the element at index, shrinking the size of the ArrayedCollection.y = [ 1, 2, 3 ]; y.removeAt(1); y.postln;

Answer a new collection which consists of the results of function evaluated for each item in the collection. The function is passed two arguments, the item and an integer index. See Collection helpfile for examples.

Iterate over the elements in order, calling the function for each element. The function is passed two arguments, the element and an index.['a', 'b', 'c'].do({ arg item, i; [i, item].postln; });

Iterate over the elements in reverse order, calling the function for each element. The function is passed two arguments, the element and an index.['a', 'b', 'c'].reverseDo({ arg item, i; [i, item].postln; });

The same as -collect, but can look inside sub-arrays up to the specified depth.a = [99, [4,6,5], [[32]]]; a.deepCollect(1, {|item| item.isArray}).postln; a.deepCollect(2, {|item| item.isArray}).postln; a.deepCollect(3, {|item| item.isArray}).postln;

For a multidimensional array, rearranges the data using the desired number of elements along each dimension. The data may be extended using wrapExtend if needed.a = [4,7,6,8]; a.reshape(2,2); a.reshape(2,3);

Interprets the array as a list of probabilities which should sum to 1.0 and returns a random index value based on those probabilities.( Array.fill(10, { [0.1, 0.6, 0.3].windex; }).postln; )

Return the number of elements the ArrayedCollection.

Returns a new Array with the receiver items normalized between min and max.[1, 2, 3].normalize; //default min=0, max= 1 [1, 2, 3].normalize(-20, 10);

Returns the Array resulting from :(this / this.sum)

so that the array will sum to 1.0.

This is useful for using with windex or wchoose.[1, 2, 3].normalizeSum.postln;

Given an array of symbols, this returns an array of pairs of (symbol, value) from the current environment. This can then be used as arguments for a Synth, or in an OSC message.e = (freq: 340, amp: 0.001, strangeness: 0.85); e.use { [\amp, \taste, \strangeness].envirPairs; }

Invert rows and columns in a two dimensional Array (turn inside out). See also: Function, SequenceableCollection.[[1, 2, 3], [4, 5, 6]].flop; [[1, 2, 3], [4, 5, 6], [7, 8]].flop; // shorter array wraps [].flop; // result is always 2-d.

Used by UGens to perform multi channel expansion. Same as flop.

Some UGens return Arrays of OutputProxy when instantiated. This method allows you to get at the source UGen.z = Pan2.ar; z.postln; z.source.postln;

Used within Routines and assumes an array of functions, from which subroutines are created. The subroutines are played while the outer Routine carries on. The join parameter expresses after how many subroutines complete the outer Routine is allowed to go on. By default this happens after all subroutines have completed.// an array of routine functions: ( a = [ { 1.wait; \done_one.postln }, { 0.5.wait; \done_two.postln }, { 0.2.wait; \done_three.postln } ]; ) // join after 0 ( Routine { "join = 0.".postcln; a.fork(0); \doneAll.postln; }.play; ) // join after 1 ( Routine { "join = 1.".postcln; a.fork(1); \doneAll.postln; }.play; ) // join after all ( Routine { "join = a.size (default).".postcln; a.fork; \doneAll.postln; }.play; ) poll(trig, label, trigid) apply an array of Poll units to an array of UGens (see those helpfiles for more details). s.boot; ( x = { SinOsc.ar([0.1, 0.2], 0).poll * 0.1 }.play; ) x.trace; // By tracing the Synth you can see the two Poll units we created x.free

apply an array of Dpoll units to an array of UGens (see those helpfiles for more details).

This method is used by IdentitySet to search for a key among its members.

This method is used by IdentityDictionary to search for a key among its members.

Returns a string representing the Array. May not be compilable due to elision (...) of excessive arguments.

Returns a string that will compile to return an Array equal to the receiver.

Returns true. Arrays are valid UGen inputs.

Returns the OSC message as an Int8Array. Receiver must be a bundle.[0.1, [\s_new, \default, -1, 1, 1, \freq, 1961]].asRawOSC;
