PropertyHandle :: IsTemporaryCollection - Is property a temporary collection
Temporary collections are collections, that have been calculated at run-time. In contrast to transient collections, temporary collections are stored in a temporary database (temporary main base).
Temporary collections may own referenced instances or not. When not owning referenced instances, those cannot be updated (canUpdate()) regardless on the current access mode.
Notes:
When the property defines a transient reference, the property set in the transient reference is checked for being a transient collection.
Return value: Return value ( logical )
The function returns YES when the question was answered positively. Otherwise it returns NO.
