protected Set<E> delegate()

Implements abstract com.google.common.collect.ForwardingSet.delegate.

Doc from com.google.common.collect.ForwardingObject.delegate.

Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet#delegate. Concrete subclasses override this method to supply the instance being decorated.

public int hashCode()

Overrides com.google.common.collect.ForwardingSet.hashCode.

Implements java.util.Set.hashCode, java.util.Collection.hashCode.

Doc from java.util.Set.hashCode.

Returns the hash code value for this set. The hash code of a set is defined to be the sum of the hash codes of the elements in the set, where the hash code of a null element is defined to be zero. This ensures that s1.equals(s2) implies that s1.hashCode()==s2.hashCode() for any two sets s1 and s2, as required by the general contract of Object#hashCode.

Returns:int

the hash code value for this set
