tripleplay.ui.util.Scale9.Axis
An unmodifiable view of a set which may be backed by other sets; this view will change as the backing sets do. Contains methods to copy the data into a new set which will then remain stable. There is usually no reason to retain a reference of type {@code SetView}; typically, you either use it as a plain {@link Set}, or immediately invoke {@link #immutableCopy} or{@link #copyInto} and forget the {@code SetView} itself. @since Guava release 02 (imported from Google Collections Library)
