org.limewire.collection
Class MultiCollection<T>

java.lang.Object
  org.limewire.collection.MultiIterable<T>
      org.limewire.collection.MultiCollection<T>

All Implemented Interfaces:

java.lang.Iterable<T>, java.util.Collection<T>

public class MultiCollection<T>
extends MultiIterable<T>
implements java.util.Collection<T>

A Collection that delegates to other collections. MultiCollection behaves as if it is all the collections combined.

    LinkedList<String> l1 = new LinkedList<String>();
    l1.add("Bob");
    l1.add("Abby");
    l1.add("Chris");        

    LinkedList<String> l2 = new LinkedList<String>();
    l2.add("Anderson");
    l2.add("Baker");
    l2.add("Cunningham");

    System.out.println("MultiCollection contains 'Baker': " + new MultiCollection<String>(l1, l2).contains("Baker"));     

    Output:
        MultiCollection contains 'Baker': true
