Element - State

Definition

A state is used to model a situation; it executes a relatively long-lasting task. The system is in the respective state while the task is being processed.

The following rules apply for states:

• A state is entered if a transition which has the state as the final point is run through.

• A state is left if a transition which leads away from the state is run through.

• A state is active as soon as it is entered. The state becomes inactive once it is left.

• The name of the state is unique within the state machine.

Icon/Notation

A state is shown as a rectangle with rounded corners.

Owner Hierarchy/Prerequisites
