Generate C++ enum class from MATLAB^® enumeration

R2026b

Whether to generate C++ enumeration classes for MATLAB enumerations

Since R2022a

Description

App Configuration Pane: C++ Language Features

Configuration Objects: coder.MexCodeConfig | coder.CodeConfig | coder.EmbeddedCodeConfig

The Generate C++ enum class from MATLAB enumeration parameter specifies whether to convert MATLAB enumerations to C++ enumeration classes. You can only set this parameter when you generate C++ code with a language standard of C++11 or later.

Individual enumerations can override this parameter by providing a generateEnumClass static method that returns true or false. When an enumeration defines this method, the method return value takes precedence over the value of the Generate C++ enum class from MATLAB enumeration parameter.

For imported enumerations, ensure that the external header file defines the enumeration using the form that matches what the code generator expects. If the code generator expects an enumeration class but the header file defines an ordinary enumeration (or vice versa), the C++ compiler reports a build error.

Dependencies

To enable this parameter, set the Language parameter to C++ and set the Language Standard parameter to C++11 (ISO) or later.

Settings

On

The code generator converts MATLAB enumerations to enumeration classes in the generated C++ code, unless you specify a generateEnumClass static method. This setting is the default.

Off

The code generator produces ordinary C enumerations for MATLAB enumerations in the generated C++ code, unless you specify a generateEnumClass static method.

Programmatic Use

Property: CppGenerateEnumClass

Values: true | false
