Themes

The Themes collection contains Theme objects representing themes based on GDB maps. Access to collection items is possible both by name and by internal number. An internal number is generated when a theme is cataloged (the Theme object is added to the Themes collection). Continuity of theme numbers is not guaranteed. Persistence of theme's internal number in GDB is guaranteed until performing GDB reorganization by the GDBEngine::CompactGDB method with the mode == gdbCompactNoKeepISN.
