IdentityBag | SuperCollider 3.12.2 Help

Description

An IdentityBag is an unordered collection of objects. In some languages it is referred to as a counted set. A Bag keeps track of the number of times objects are inserted and requires that objects be removed the same number of times. There is only one instance of an object in a Bag even if the object has been added to the Bag multiple times (test is for identity).

The contents of a IdentityBag are unordered. You must not depend on the order of items in a set.

.remove(item, count: 1)

From superclass: Bag

Remove anObject from the IdentityBag.IdentityBag[1, 2, 3].remove(3);

.contents

From superclass: Bag

Returns the dictionary that stores the objects in pairs (obj -> numberOfObjects)IdentityBag[\a, \b, \c, \c].contents;

Iteration

.do(function)
