IDataSourceListener Interface and Methods

Implemented by the OSP Data Object.

The methods of IDataSourceListener notify the data consumer that an existing data member has become available, unavailable, or has been refreshed. The data consumer should release its hold on any data access interfaces for that member and call IDataSource::getDataMember to get the new data (if available).

The IDataSourceListener methods used with OSP are described in the following table.

Method Description
dataMemberAdded Notifies the data consumer that an existing data member has become available, unavailable, or has been refreshed.
dataMemberChanged Notifies the data consumer that an existing data member has changed.
dataMemberRemoved Notifies the data consumer that an existing data member has been removed.
