MetaScript functions

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
