Fields
Remarks
If an evaluation of the ICacheTriggerEntry object
representing a pending change fails (returns false), then one
of the following actions is taken:
- Rollback - an ArgumentException is thrown by the trigger to reject the operation that would result in this change (default);
- Ignore - the change is ignored and the entry's value is reset to the original value returned by the OriginalValue;
- Remove - the entry is removed from the underlying backing cache using the Remove(Boolean) call.
