matlab.DiscreteEventSystem class

Package: matlab
Superclasses: matlab.System

Base class for discrete-event system objects


matlab.DiscreteEventSystem is the base class for discrete-event System objects. In your class definition file, you must subclass your object from this base class (or from another class that derives from this base class). Subclassing allows you to use the implementation and service methods provided by this base class to build your object. For more information about implementing matlab.DiscreteEventSystem class with MATLAB Discrete-Event System block, see Create Custom Blocks Using MATLAB Discrete-Event System Block.

Type this syntax as the first line of your class definition file to directly inherit from the matlab.DiscreteEventSystem base class, where ObjectName is the name of your object:

classdef ObjectName < matlab.DiscreteEventSystem

Define as public these methods:

  • blocked

  • destroy

  • entry

  • exit

  • generate

  • iterate

  • setupEvents

  • timer

For other methods, set Access = protected.

matlab.DiscreteEventSystem Class Methods

This list contains the methods to implement and the utility methods inherited from the matlab.DiscreteEventSystem base class. For more information about implementing a discrete-event System object™, see Create a Discrete-Event System Object. For information about linking the discrete-event System object to a SimEvents® model and creating a custom behavior, see Delay Entities with a Custom Entity Storage Block.
