SAS/AF Software Procedure Guide

INTRFACE Entries

INTRFACE entries (also referred to simply as interfaces) store abstract method definitions, which define shared methods that FRAME components can use to communicate with each other. You use the BUILD procedure's Interface Editor window to create, edit, or remove method definitions in INTRFACE entries.

Method definitions in INTRFACE entries consist of the method name and, optionally, the method signature. The method signature specifies the name, order, type, and description of the method's arguments. The code that implements the methods is not stored in the INTRFACE entry. Rather, a class that uses the methods defined in the interface to communicate with another class indirectly calls the corresponding methods in the other class.

For an introduction to using interfaces to implement model/view communications, refer to SAS Guide to Applications Development.
