Class ForwardingSet<E>

java.lang.Object
org.glassfish.jersey.internal.guava.ForwardingCollection<E>
org.glassfish.jersey.internal.guava.ForwardingSet<E>
All Implemented Interfaces:
Iterable<E>, Collection<E>, Set<E>
Direct Known Subclasses:
ForwardingSortedSet
public abstract class ForwardingSet<E> extends ForwardingCollection<E> implements Set<E>
A set which forwards all its method calls to another set. Subclasses should override one or more methods to modify the behavior of the backing set as desired per the decorator pattern.

Warning: The methods of ForwardingSet forward indiscriminately to the methods of the delegate. For example, overriding ForwardingCollection.add(E) alone will not change the behavior of ForwardingCollection.addAll(java.util.Collection<? extends E>), which can lead to unexpected behavior. In this case, you should override addAll as well, either providing your own implementation, or delegating to the provided standardAddAll method.

The standard methods are not guaranteed to be thread-safe, even when all of the methods that they depend on are thread-safe.

  • Method Details

    • delegate

      protected abstract Set<E> 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 delegate(). Concrete subclasses override this method to supply the instance being decorated.
      Specified by:
      delegate in class ForwardingCollection<E>

    • equals

      public boolean equals(Object object)
      Specified by:
      equals in interface Collection<E>
      Specified by:
      equals in interface Set<E>
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Specified by:
      hashCode in interface Collection<E>
      Specified by:
      hashCode in interface Set<E>
      Overrides:
      hashCode in class Object

    • toString

      public String toString()
      Returns the string representation generated by the delegate's toString method.
      Overrides:
      toString in class Object
