- class sismic.clock.Clock¶
Abstract implementation of a clock, as used by an interpreter.
The purpose of a clock instance is to provide a way for the interpreter to get the current time during the execution of a statechart.
- class sismic.clock.SimulatedClock¶
A simulated clock, starting from 0, that can be manually or automatically incremented.
Manual incrementation can be done by setting a new value to the time attribute. Automatic incrementation occurs when start() is called, until stop() is called. In that case, clock speed can be adjusted with the speed attribute. A value strictly greater than 1 increases clock speed while a value strictly lower than 1 slows down the clock.
Clock will be automatically updated both based on real time and its speed attribute.
- Return type
- property speed: float¶
Speed of the current clock. Only affects time if start() is called.
- Return type
- class sismic.clock.UtcClock¶
A clock that simulates a wall clock in UTC.
The returned time value is based on Python time.time() function.
- class sismic.clock.SynchronizedClock(interpreter)¶
A clock that is synchronized with a given interpreter.
The synchronization is based on the interpreter’s internal time value, not on its clock. As a consequence, the time value of a SynchronizedClock only changes when the underlying interpreter is executed.
