Remarks

This is the data source that the TopFederatedResultsWebPart uses to gather data. It is the intermediary between the consuming TopFederatedResultsWebPart and the TopFederatedResultsDataSourceView, which is the object that gathers the data. It contains similar properties to the TopFederatedResultsWebPart and passes these configuration values to the TopFederatedResultsDataSourceView.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
