activate method

SamModel activate (
  1. {bool bLog: false}
)
inherited

Activate the SamModel after assert validation.

It asserts that the following is true:

  1. that the SamModel is not in the SE.ss_broken state.
  2. that the SamModel is in the SE.ss_virgin state.
  3. that at least one state has been defined in SamState
  4. that all states in the Enums have been defined.
  5. that all actions in the Enums have a handler
  6. that all naps in the SamState definitions have a handler
  7. that all next, allow and ignore values the SamState definitions are valid (The compiler should also report this).

It then moves the SamModel into the first DefState defined in the SamState by issuing a proposal to SamModel.present (which may execute a nap function).

Implementation

  _ss.ssMap['${SE.ss_virgin}'].next(_ss.firstState);

  // at this point all tables must be complete so we validate what we can
