Interface UserRoleDbPersister

All Superinterfaces:

Persister

public interface UserRoleDbPersister
extends Persister

This interface describes the set of methods that all database persisters for UserRole objects must implement. UserRole objects represent a user's secondary institution roles.

A database persister allows an object to be stored (either inserted or updated) within the database or to be deleted from the database. Persisting methods are named according to the type of persistence that is performed.

Inserts or updates the supplied UserRole using the supplied connection. The connection must be to the same database as is used by the associated persistence manager. If the object's id is set and is associated with this persistence manager's same container, then an update is done, otherwise a new object is inserted.

Throws:

ValidationException - if the object is not in a consistent state to be persisted.
