描述

MATLAB。DiscreteEventSystemis 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 implementingMATLAB。DiscreteEventSystem与MATLAB Discrete-Event Systemblock, see使用MATLAB离散事件系统块创建自定义块。

Type this syntax as the first line of your class definition file to directly inherit from theMATLAB。DiscreteEventSystem基础班，哪里ObjectNameis the name of your object:

classdefObjectName < matlab.DiscreteEventSystem

Create a Custom Entity Storage Block to Delay Entities

此示例显示了如何使用离散事件系统对象方法创建具有一个输入端口，一个输出端口和一个存储元素的自定义实体存储块。离散事件系统对象是MATLAB。DiscreteEventSystem类，您可以使用此类提供的实现和服务方法。然后，您使用MATLAB Discrete-Event Systemblock to integrate the System object into a SimEvents model. The customMATLAB Discrete-Event Systemblock accepts an entity from its input port and forwards it to its output port with a specified delay. For more information, see使用自定义实体存储块延迟实体。
