tryAddDeferred

tryAddDeferred(value: MemberType): Boolean receiverByReference, updating;

The tryAddDeferred method of the DynaDictionary class attempts to add the value specified by the value parameter to the dynamic dictionary if it is not already present. For persistent dictionaries, the attempt is queued and executed when the database transaction commits. For transient dictionaries, the attempt is executed immediately.

This method returns true if the dictionary is persistent or the dictionary is transient and the value was added; otherwise it returns false.
