Interface COM.odi.odmg.Set

public interface Set
extends Collection

The Set interface is a subinterface of the Collection interface. The Set interface encapsulates the operations on a set.

All methods throw the following exceptions:

COM.odi.odmg.TransactionNotInProgressException If there is no transaction in progress.

COM.odi.ObjectStoreException If the current thread is not associated with a transaction or if the instance in question is not associated with the current thread.

Methods that modify persistent objects throw this exception:

COM.odi.odmg.DatabaseIsReadOnlyException If there is a readonly transaction in progress or if the database is open for readonly.
