At run-time, an Object instance can have specific values for its attributes, or exist in a particular state. To model the varying behavior of Objects at run-time, use instance values and run-time states.

Typically there is interest in the run-time behavior of Objects that already have a classifier set. You can select from the classifier's attribute list and apply specific values for your Object instance. If the classifier has a child State Machine, its States propagate to a list where the run-time state for the Object can be defined. To do this, see the following topics:

The following example defines run-time values for the listed variables, which are attributes of the instances' classifier AccountItem.
