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 the
Guide to SAS/AF Applications Development.
