addDataSourceManagerListener

public void addDataSourceManagerListener(DataSourceManagerListener listener)

Adds a listener to data source manager events.

The listener will receive DataSourceManagerEvents whenever a datasource is added or removed from this manager, through the use of methods addDataSource and removeDataSource.
