Description copied from class:ImmutableCollection
Returnstrue
if this immutable collection's implementation contains references to user-created objects that aren't accessible via this collection's methods. This is generally used to determine whethercopyOf
implementations should make an explicit copy to avoid memory leaks.- Specified by:
