SuperCollider has a rich hierarchy of Collection subclasses, detailed below. Subclasses of a given class are indented (sub-lists) relative to the class. Most of these subclasses have their own helpfiles. Classes labelled "abstract" are not for direct use, but classes lower down the tree may inherit methods from them. For this reason it is important to consult the helpfiles of classes farther up the tree in order to get a complete list of available methods.

Collection - abstract superclass of all Collection subclasses; many methods are inherited from this class
