What is the purpose of EVFlag.fMethod ?

[Francois Van Lerberghe]

Hello

I'm using Valentina with Realbasic.
I wonder what is the purpose of EVFlag.fMethod

If I want to create a method field using the class way, I may write :

    num = new VULong(  "myNumericField", EVFlag.fNone, "myStringField" )

Or, must I write :
    
    num = new VULong(  "myNumericField", EVFlag.fMethod, "myStringField" )
                                                ^^^^^^^
When must I use EVFlag.fMethod ?

Thank you in advance.
