  • Method Details

    • newEmpty

      OrderedIterableMultimap<K,V> newEmpty()
      Description copied from interface: Multimap
      Creates a new instance of the same implementation type, using the default capacity and growth parameters.
      Specified by:
      newEmpty in interface Multimap<K,V>

    • get

      OrderedIterable<V> get(K key)
      Description copied from interface: Multimap
      Returns a view of all values associated with the given key.

      If the given key does not exist, an empty RichIterable is returned.

      Specified by:
      get in interface Multimap<K,V>
      Parameters:
      key - the key to search for

      Description copied from interface: Multimap
      Returns all elements of the source multimap that satisfies the predicate. This method is also commonly called filter. 
      e.g.
 return multimap.selectKeysValues(new Predicate2<Integer, Person>()
 {
     public boolean accept(Integer age, Person person)
     {
         return (age >= 18)

     }
 });
      Specified by:
      selectKeysValues in interface Multimap<K,V>
      Parameters:
      predicate - a Predicate2 to use as the select criteria
      Returns:
      Multimap, which contains elements as a result of the select criteria

      predicate - a Predicate2 to use as the reject criteria
      Returns:
      Multimap, which contains elements that don't satisfy the predicate

     public boolean accept(Integer age, Iterable<Person> values)
     {
         return (age >= 18)
                  && ((RichIterable<Person>)values.size() >= 2);
