isPartialView

boolean isPartialView()

Description copied from class: ImmutableCollection

Returns true 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 whether copyOf implementations should make an explicit copy to avoid memory leaks.

Specified by:

isPartialView in class ImmutableCollection<K>
