When you define a class for an information model, you specify the interfaces that the class implements. For each of those interfaces, you specify the members (properties, methods, and collections) that are attached to the interface.
The definition of a method as a member of an interface does not result in the method's implementation logic being stored in the repository. However, it does add the method name to the set of defined member names for that interface. It also reserves the method's dispatch identifier in the set of defined dispatch identifier values for the interface.
Instances of the MethodDef class represent method definitions.
To attach a new method to an interface, use the InterfaceDef class.
Use the MethodDef class to access or modify the characteristics of a method definition, or to determine the interface definition to which a particular method is attached.
