org.apache.myfaces.trinidad.model.RowKeySetImpl
Implements a set of rowKeys. This set is connected with a CollectionModel and is actually a subset of the rowKeys contained by the CollectionModel. This set is used to group together rows that have a common UI property. For example, all the rows that are currently selected by a user might be placed in a single RowKeySet.
This class has very efficient implementations for addAll, clear and invertAll. @author The Oracle ADF Faces Team
