Detailed Call Sequence

The call sequence diagrams show the order in which internal methods are called when you run the specified method. If your System object™ does not overwrite a specified method, the default implementation of that method is used.

If you want a more abstract view of the method calls, see Summary of Call Sequence.

setup Call Sequence

When you run a System object for the first time, setup is called to perform one-time set up tasks. This sequence of methods is called:

  1. If the System object is not in use, release

  2. validatePropertiesImpl

  3. isDiscreteStateSpecificationMutableImpl

  4. isInputDataTypeMutableImpl

  5. isInputComplexityMutableImpl

  6. isInputSizeMutableImpl

  7. isTunablePropertyDataTypeMutableImpl

  8. validateInputsImpl

  9. If the System object uses nondirect feedthrough methods, call isInputDirectFeedthroughImpl

  10. setupImpl

Running the Object or step Call Sequence

When you run a System object in MATLAB®, either by calling the object as a function or calling step, this sequence of methods is called:

  1. If the System object is not in use (object was just created or was released),

    1. release

    2. setup

    3. reset

    Else, if the object is in use (object was called and release was not called)

    1. If tunable properties have changed

      1. validatePropertiesImpl

      2. processTunedPropertiesImpl

    2. If the input size, data type, or complexity has changed

      1. validateInputsImpl

      2. processInputSpecificationChangeImpl

reset Call Sequence

When reset is called, these actions are performed.

  1. If the object is in use (object was called and not released), call resetImpl

release Call Sequence

When release is called, these actions are performed.

  1. If the object is in use (object was called and not released), call releaseImpl
