Composite function - ObjectVision/GeoDMS GitHub Wiki

definition

Composite functions are functions generating one or more subitems (e.g. select_with_org_rel, GridDist)

caching

The direct results (generated subitems) are session-specific.

Indirect results, calculated with expressions that are not only direct references to such subitems can be stored persistently.

In this way they differ from the session-specific functions.
