How do I import BITFIELD_TEXTTABLE CompuMethods with the AUTOSAR ARXML Importer?

I want to import the AUTOSAR "CompuMethods" of category "BITFIELD_TEXTTABLE" from an ARXML file in order to access the bitfields defined in my model.

Which versions of MATLAB support "CompuMethods" in such a way that I can access directly the fields, as I would do with "bus" or "enum" ?

This functionality is available as of R2019a.

Given the ARXML file "MyARXML", the following commands will generate "QF_defineIntEnumTypes.m" which can be used to access the BITFIELD_TEXTTABLE compu method enumeration data types.  

>> arProps = autosar.api.getAUTOSARProperties("CTRV")
>> createEnumeration(arProps,"/Pkg_CompuMethods/SomeCompuMethod") 
//Found AUTOSAR enumeration types. You can use SomeCompuMethod_defineIntEnumTypes.m to recreate these enumeration types.

This will generate "SomeCompuMethod_defineIntEnumTypes.m" and give you access to the enumeration data.

For context, when you import an ARXML file and create a component, the BITFIELD_TEXTTABLE category is not automatically imported because Simulink allows users to customize what information they want to pull in. This is similar behavior to importing a "math" library in some programming languages.
