Backup


Unit:SDL_geomap
Class: TSymbolRepository
Declaration: procedure Backup;

The method Backup copies the entire set of currently defined symbols into an internal memory buffer. The symbols can be restored from this backup buffer by using the method Restore.

Hint: Backup and Restore can be especially useful when the user is allowed to edit the symbol list. Simply call Backup before displaying the symbol editor, and call Restore in the case the user cancels the editor. This way you can easily undo any changes applied by the user.
