getEntityPortsImpl

Class: matlab.DiscreteEventSystem
Namespace: matlab

Define input ports and output ports of discrete-event system

Syntax

[inputTypes,outputTypes]=getEntityPortsImpl(obj)


Description

[inputTypes,outputTypes]=getEntityPortsImpl(obj) defines input ports and output ports of a discrete-event system.

Input Arguments

obj — Discrete-event System object™

MATLAB^® object

Discrete-event System object.

Output Arguments

inputTypes — Input types

cell vector of character vectors

Input port types of a discrete-event system, specified as a cell vector of character vectors with a length that is the same as the number of input ports.

The Nth element of the vector that specifies the type of the Nth input port.

• If the port is an entity port, the character vector indicates the entity type name of this port. The name must match one of the entity types specified in getEntityTypesImpl.

• If the port is a signal port, the character vector must be empty ('').

outputTypes — Output types

cell vector of character vectors

Output port types of a discrete-event system, specified as a cell vector with a length that is the same as the number of output ports.

The Nth element of the vector that specifies type of the Nth output port.

• If the port is an entity port, the character vector indicates the entity type name of this port. The name must match one of the entity types specified in getEntityTypesImpl.

• If the port is a signal port, the character vector must be empty ('').

Examples

Get Entity Inputs and Outputs for Discrete-Event System

Get entity input and output port types for discrete-event system.

function [inputTypes,outputTypes] = getEntityPortsImpl(obj)
    % Specify input and output port types.
    %
    % This implementation further specifies port type and entity
    % type at these inputs and outputs:            
    % Inputs:
    % 1. Signal port
    % 2. Entity port receiving entities of type 'entity1'
    % 3. Entity port receiving entities of type 'entity2'
    % Outputs:
    % 1. Signal port
    % 2. Entity port sending entities of type 'entity2'          
    %
    % The discrete-event system must have already defined:
    % - 3 inputs (by method 'getNumInputsImpl') and
    % - 2 outputs (by method 'getNumOutputsImpl')
    inputTypes = {'', 'entity1', 'entity2'};
    outputTypes = {'', 'entity2'};
