State Machine Building Blocks

A State Machine combines states and transitions, with regions for concurrent configurations and pseudostates for routing:

• Regions - Group the states of an orthogonal configuration.
• States - Define simple, composite, orthogonal, and final states.
• Pseudostates - Use choice, junction, fork, join, and history.
• Transitions - React to events, continue automatically, or execute internal behavior.

See State Machine Concepts for event processing and transition selection.
