![]() | UpdateListenerUpdate Method |
If the call to Update contains new (inserted) events, then the first argument will be a non-empty list and the second will be empty. Similarly, if the call is a notification of deleted events, then the first argument will be empty and the second will be non-empty.
Either the newEvents or oldEvents will be non-null. This method won't be called with both arguments being null, (unless using output rate limiting or force-output options), but either one could be null. The same is true for zero-length arrays.
