MetaScript functions - ObjectVision/GeoDMS GitHub Wiki

Metascript functions are used to generate script (like for_each) or request information on tree items like SubItem_PropValues

• for_each_ind - generate a set of items for each element of a domain, new variant
• for_each - generate a set of items for each element of a domain
• loop - instantiate a template until a stop condition is met

• SubItem_PropValues - a domain unit with a string attribute containing the property values of the direct subitems

• Inherited_PropValues - a domain unit with a string attribute containing the property values of the direct subitems of the item argument and of all referred items in the namespace.

• SubTree_PropValues - a domain unit with a string attribute containing the property values of all subitems

• subitem - access a subitem by name

• DocData - introspection: all registered operators as data

• DocStorageManagers - introspection: all registered storage managers as data

• iterate - instantiates a template per iteration name and chains currValue/nextValue; the result exposes lastValue

• Generate - triggers the generation of the storages under the target item

• GenerateDirect - as Generate, without scheduling indirection

• IntegrityCheck - the operator behind the IntegrityCheck property: a failing check makes the item unreadable

• DataArray - the compiled form of a [...] data literal

• SequenceArray - the compiled form of a sequence data literal ('{n: ...}' entries)

• do - alias of expand
