iterator
Description copied from class:ImmutableCollection
Returns an unmodifiable iterator across the elements in this collection. -
asList
Description copied from class:ImmutableCollection
Returns anImmutableList
containing the same elements, in the same order, as this collection.Performance note: in most cases this method can return quickly without actually copying anything. The exact circumstances under which the copy is performed are undefined and subject to change.
- Overrides:
asList
in classImmutableCollection<E>
-
isPartialView
boolean isPartialView()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:
isPartialView

Copies the contents of this immutable collection into the specified array at the specified offset. Returnsoffset + size()
