All Known Subinterfaces:

All Known Implementing Classes:

public interface ObjectCollection<K>
extends java.util.Collection<K>, ObjectIterable<K>

A type-specific Collection; provides some additional methods that use polymorphism to avoid (un)boxing.

Additionally, this class defines strengthens (again) iterator().

This interface specifies reference equality semantics (members will be compared equal with == instead of equals), which may result in breaks in contract if attempted to be used with non reference-equality semantics based Collections. For example, a aReferenceCollection.equals(aObjectCollection) may return different a different result then aObjectCollection.equals(aReferenceCollection), in violation of equals's contract requiring it being symmetric.
