State shape

In a statechart or activity diagram, a state UML State shape icon is a condition during which an object satisfies a condition, performs an action, or waits for an event. A state is an image of an instant in the life of an object that reflects the values that exist in the object's attributes and the links the object has with other objects.

A state has two compartments for optional information. The top compartment contains a name and the bottom compartment contains a list of internal actions or activities performed in response to events. When a state corresponds to ongoing activity, that activity is expressed either as a nested state machine or by a pair of entry and exit actions.
