tryCopyFrom

tryCopyFrom(sourceCollection: Collection) lockReceiver, updating;

The tryCopyFrom method of the DynaDictionary class copies the values that are not present in the receiver from the collection specified in the sourceCollection parameter to the receiver.

Dictionary implementations (including the MemberKeyDictionary and DynaDictionary classes) support copying to an ExtKeyDictionary class with compatible keys.

Exception 1312 (Class of value passed to a collection method incompatible with membership) is raised if the member types are not compatible or exception 1000 (Invalid parameter type) for dictionary types if the keys are not compatible.
