generic class EnumerationParameter from Dynamic (Enum as any)
inherits
Parameter from Dynamic
---Purpose: This generic class defines a parameter with a given
-- enumeration. For correct use an instanciation of this
-- class, the Convert method must be defined. This
-- method is automaticaly called by the constructor which
-- takes a CString as value for the enumeration. The
-- prototype of the Convert method must be described as
-- follows :
--
-- void Convert(const Standard_CString,Enum);
--
-- The prototype and the body of this method, can be
-- written in the file <mypackage.cxx> where the
-- enumeration is described. No declaration of the
-- Convert method in any .cdl file is necessary.
