Class UML 2.4.1::ProtocolTransition
Description:
A protocol transition specifies a legal transition for an operation. Transitions
of protocol state machines have the following information: a pre condition
(guard), on trigger, and a post condition. Every protocol transition is
associated to zero or one operation (referred BehavioralFeature) that belongs
to the context classifier of the protocol state machine.

ElementConstraints:
Signature: refers_to_operation() : Boolean;
Description: If a protocol transition refers to an operation (i. e. has a call trigger
corresponding to an operation), then that operation should apply to the
context classifier of the state machine of the protocol transition.
Expression: true
Signature: belongs_to_psm() : Boolean;
Description: A protocol transition always belongs to a protocol state machine.
Expression: container.belongsToPSM()
Signature: associated_actions() : Boolean;
Description: A protocol transition never has associated actions.
Expression: effect->isEmpty()
Operations:
No additional operations.
