About the OpenListener interface

Methods  

Implemented by OpenAdapter

This interface is used as a notification when a DataSet is opened or closed. This is especially useful when your application uses many lookup tables. You may verify whether or not a DataSet is open before performing a lookup, open it as necessary to perform the lookup, then close it to improve performance.
