org.apache.myfaces.trinidad.model.RowKeySet
This Set is a mutable collection of rowKeys. This class is meant to be used with models that have a current rowKey concept. Therefore, the {@link #add()}, {@link #remove()} and {@link #isContained} methodsdo not need to take the rowKey as an argument, since the rowKey is implied. The implied key is obtained by calling {@link #getRowKey()}
Because this Set has a reference to the underlying model, operations like {@link #addAll()}, {@link #removeAll()} and {@link #invertAll()} mayexecute in constant time.
Note that the {@link #size()} method on the this Set might be expensive tocompute. Use the {@link #getSize()} method on this class for an inexpensive size. @author The Oracle ADF Faces Team
