Method Detail

delete

protected void delete(Object value,
                      EOEditingContext ec)

Deletes the object value from EOEditingContext ec. Value must either be an Object[] of EOGlobalIDs, an NSArray of EOGlobalIDs, an NSDictionary representing an EO primary key, an EOGlobalID, or an EOEnterpriseObject.

Parameters:

value - object(s) to delete

ec - EOEditingContext to delete objects from

invoke

public Object invoke()

Deletes one or more EOEnterpriseObject's identified by global ID in the argument values. All argument values are expected to be EOGlobalID's. For each global ID, a corresponding fault is created in the operation's editing context. The EO is then deleted using the delete method.

If WOServiceUtilities.commitOperationImmediately() is true, then the changes to the editing context are saved before this method returns.

Overrides:

invoke in class WOOperation

Returns:

an empty NSArray on success
