Class Description
The WebObjects Framework adds one method to the Enterprise
Objects Framework's EOEditingContext class that atempts to commit
changes made in the receiver to its parent EOObjectStore.
Instance Methods
- (NSException *)tryToSaveChanges
Attempts to commit changes made in the receiver
to its parent EOObjectStore by sending it the message saveChangesInEditingContext:.
If the parent is an EOObjectStoreCoordinator, it guides its EOCooperatingObjectStores,
typically EODatabaseContexts, through a multi-pass save operation
(see the EOObjectStoreCoordinator class specification for more information).
If no message handler or delegate is available and a database error
occurs, an exception is raised that can be caught in WebScript; the
error message indicates the nature of the problem.
