The Clipboard: 2 Transfer Data Structures

Up: GEOS SDK TechDocs | Up | Down | Prev: 1 Overview | Next: 3 Using The Clipboard

Both the Clipboard and quick-transfer mechanisms use similar structures to accomplish data transfer. These data structures are owned and managed by the GEOS User Interface; however, they are accessible to all geodes in the system through a number of routines and messages.

The Clipboard consists of a VM file known as the Transfer VM File. The quick-transfer mechanism uses the same file for its data transfer. Typically, this is a file designated and managed by the User Interface.

In addition, certain formats of data are supported automatically--GEOS text and graphics strings are special formats that are described below. Geodes can create their own specific formats; for example, GeoManager uses a special format for quick-transfer of files between disks and directories.
