A ImportList.T is a set of interface names. The procedure Get generates such a list. It takes a Type.Object and looks at all its components to construct a list of all necessary imports to represent the type in a Modula-3 program.

A procedure Add can be used to add other interfaces to the list. ToText produces a comma separated list of all interface names (useful for IMPORT statements).

INTERFACE ImportList;

IMPORT Atom, Type;

TYPE
  T <: REFANY;
  MethodList = REF ARRAY OF Method;
  Method = RECORD
             name: Atom.T;
             sig : Type.Signature
           END;

PROCEDURE FromType (type: Type.Object; methods: MethodList): T;
Generate a new import list. Look for fields in type and for signature of methods in methods.

PROCEDURE Add (importList: T; intf: Atom.T);
Add the interface name intf to importList. This is a no-op if intf is already in the list

PROCEDURE ToText (imports: T): TEXT;
Generate a comma separated list of interface names out of imports. The output is suitable for an IMPORT statement.

END ImportList.
