tryRemoveDeferred

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

The tryRemoveDeferred method of the ExtKeyDictionary class attempts to remove the value specified in the value parameter from the external key dictionary if it is 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 removed; otherwise it returns false.
