Slots

A class is associated with a set of slots.

Slots are used for storing information associated with a class and its instances. A slot is described by a slot specifier. Each slot specifier includes the name of the slot and zero or more slot options. A class is also associated with a set of class options, which are slot options with a common value for the whole class. Slot options and class options control the following:

: determining default initial values for a given slot
reading and writing the values of slots
controlling whether a value for a given slot is shared by all instances of a class or whether each instance has its own value for the slot
supplying a set of initialization arguments and default values to be used when instances are created
