Statechart objects

Statecharts can contain states, data, events, transitions, entry/exit points, and annotations. States can themselves contain other states, data, events, transitions, entry/exit points, and annotations — nesting can continue indefinitely.

Graphical objects (with toolbar icons)

• Initial state
• Atomic state
• Composite state (exclusive composition)
• Parallel state (parallel composition)
• Transition
• Entry point
• Exit point
• History (history state)
• Note (annotation)

Non-graphical objects

Additional non-graphical elements (data, events, etc.) can also be defined and attached to statechart elements — covered in "Create statecharts."
