An object of the ODDesc class is a wrapper for a descriptor structure (type AEDesc), the basic structure used for building Apple event attributes and parameters.

Description
An Apple event descriptor structure consists of a handle to data and a descriptor type that identifies the type of data to which the handle refers. An object of the ODDesc class stores the actual data. To use the Apple Event Manager functions on an ODDesc object, you must first extract the data from it and then create a descriptor structure from that data.
The ODDesc class provides methods for placing and extracting the Apple event descriptor it contains. To convert from an ODDesc descriptor object to type AEDesc, you may copy the raw data and the descriptor type using the utility routines ODDescToAEDesc and AEDescToODDesc.
For more information on Apple events and the AEDesc type, see the "Introduction to Apple Events" chapter of Inside Macintosh: Interapplication Communication. For general information on scripting support in OpenDoc, see the chapter on semantic events and scripting in the OpenDoc Programmer's Guide for the MacOS.
