PropertyHandle :: IsTransientCollection - Is property a transient collection
Transient collections are collections, that have been calculated at run-time. In contrast to temporary collections, transient collections are not stored in a temporary database (temporary main base) but in memory, only. Hence, transient collections are faster but require more memory.
Transient 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 .
