Application-Defined Routines

The AEResolve function performs tasks that are required to resolve any object specifier record, such as parsing its contents, keeping track of the results of tests, and handling memory management. When necessary, AEResolve calls application-defined functions to perform tasks that are unique to the application, such as locating a specific Apple event object in the application's data structures or counting the number of Apple event objects in a container.

AEResolve can call two kinds of application-defined functions:

• Object accessor functions locate Apple event objects. Every application that supports simple object specifier records must provide one or more object accessor functions.
• Object callback functions perform other tasks that only an application can perform, such as counting, comparing, or marking Apple event objects. You can provide up to seven object callback functions, depending on the needs of your application.

This section provides model declarations for the object accessor functions and object callback functions that your application can provide.
