How do I list values of the Simulink Enumeration definitions ?

조회 수: 63(최근 30일)
So I am trying to write a script to parse the .sldd format of simulink data dictionary.
I need to get all the possible values of an enumeration type as string.
I can list enum type definitions by:
enumTypeDefs = find(sectionObj, '-value','-class','Simulink.data.dictionary.EnumTypeDefinition')
This returns an array of Entry ebjects.
After this command when I run
getValue(enumTypeDefs(1))
It returns and displays values as part of Simulink.data.dictionary.EnumTypeDefinition class object.
I took a look at the documentation and saw that there isn't a property or method that returns all the values, you can return default value etc. but not all of them. https://nl.mathworks.com/help/simulink/slref/simulink.data.dictionary.enumtypedefinition-class.html
Also there isn't a method to return the number of elements in the enumeration type, this makes me unable to iterate over and return values one by one since I don't know the boundry of the iteration index.
I'd be glad If someone helped.
Thanks.

I don't know if it's still an open Q, but since i found it while looking for the same thing, here's how I did it.
Once you have the Entry objects, get their Value with getValue, this/these will be EnumTypedefinition object(s).
Then one of the properties of an EnumTypeDefinition object is "Enumerals", hence:
enumDefList = <enumTypeDefObject>.Enumerals
will return a structure array holding Name, Value and Description of the enumerated type.
I'm using 2020a at the moment.

@Eric
using enumeration you extract the arrays of enumerated objects and labels :
>> [ gg, hh ] = enumeration( 'tryEnum01' )
gg =
4×1 tryEnum01 enumeration array
AA
BB
CC
KK
hh =
4×1 cell array
{'AA'}
{'BB'}
{'CC'}
{'KK'}
<<
now gg is an array of enumerated objects including their numerical values
scalar-expanding the array within a "double" call:
>> indexes = double( gg(:) )
indexes =
0
2
4
6
<<
and you can make use of "methods" and "properties" on members of gg: only the list of methods is populated and useful

Hello Ozan
Although it is not a direct answer to your question, I see that the following post may be helpful

I have the same question as Ozan. I have Simulink enumerations loaded in my workspace using the command:
Simulink.defineIntEnumType('epb_parkbrakeswitch_SL_T',{'PB_SWITCH_NEUTRAL','PB_SWITCH_UP','PB_SWITCH_DOWN'},[2,4,6]);
I have other scripts that run which are able to get the names of the loaded enumeration classes and even the enumeration members for the class. However how can I programatically access the values [2,4,6]? I need this for other purposes and I can't seem to figure out how to have those returned to me upon inspection.
Thank you.
