Actor Class –

Definition:
The basic component of a ROOM (Real-Time Object-Oriented Modeling) structure diagram. The space inside the actor can contain:

• Actor References: Instances of other actor classes.
• Behaviour End Ports: Ports used by the internal behaviour of the actor to communicate.
• Reference Ports: Ports that connect to other actors.
• Bindings: Connections between ports inside the actor class.
• Layer Connections: Represent layered architecture dependencies.

The border of the actor class can contain:

• Class Relay Ports: Allow relaying of communication to internal actors.
• Class End Ports: External interfaces for communication (entry/exit points).
