You can edit enumerations by right-clicking on any model element in the "model content" window.
The enumeration editing window:
The defined enumeration is a class in the model's type system.
For example, you can return a list of the values. This returns a collection of ImportColumn Tuples.
ImportColumn.allInstances
Convert this to a list of strings for each Enum value (for example to be used in a list on screen):
ImportColumn.allInstances.asString
Select an Enum value from the list, then get the string value from that:
ImportColumn.allInstances->select(ic|ic = #JournalName).asString
Get the value of an Enum tuple:
(#JournalName).toString
(note: asString does not work on Enum tuples)
Checking if a collection includes a value
You can't use the includes operator on collections of Enum. You have to select the value and check if you get a "hit".
This works:
SysSingleton.SO.ActiveUser.UserModes->select(x|x = #Consultant)->notEmpty
This does not work: SysSingleton.SO.ActiveUser.UserModes->includes(#Consultant)
Checking the ordinal number of a enum value
MyEnum.allinstances.Indexof(someObject.SomeEnumProp)
