Basic implementation of the ListMultimap interface. It's a wrapper around AbstractMapBasedMultimap that converts the returned collections into Lists. The createCollection() method must return a List.

Author(s):

Since:
2.0 (imported from Google Collections Library)
 
 abstract class AbstractListMultimap<K, V>
     extends AbstractMapBasedMultimap<K, V> implements ListMultimap<K, V> {
  
Creates a new multimap that uses the provided map.

Parameters:
map place to store the mapping from each key to its corresponding values
 
   protected AbstractListMultimap(Map<K, Collection<V>> map) {
     super(map);
   }
 
   @Override abstract List<V> createCollection();
 
   @Override
     return ImmutableList.of();
   }
 
   // Following Javadoc copied from ListMultimap.
 
  

Because the values for a given key may have duplicates and follow the insertion ordering, this method returns a java.util.List, instead of the java.util.Collection specified in the Multimap interface.

 
   @Override public List<V> get(@Nullable K key) {
     return (List<V>) super.get(key);
   }

  

Because the values for a given key may have duplicates and follow the insertion ordering, this method returns a java.util.List, instead of the java.util.Collection specified in the Multimap interface.

 
   @Override public List<V> removeAll(@Nullable Object key) {
     return (List<V>) super.removeAll(key);
   }

  

Because the values for a given key may have duplicates and follow the insertion ordering, this method returns a java.util.List, instead of the java.util.Collection specified in the Multimap interface.

 
   @Override public List<V> replaceValues(
       @Nullable K keyIterable<? extends V> values) {
     return (List<V>) super.replaceValues(keyvalues);
   }

  
Stores a key-value pair in the multimap.

Parameters:
key key to store in the multimap
value value to store in the multimap
Returns:
true always
 
   @Override public boolean put(@Nullable K key, @Nullable V value) {
    return super.put(keyvalue);
  }

  

Though the method signature doesn't say so explicitly, the returned map has java.util.List values.

  @Override public Map<K, Collection<V>> asMap() {
    return super.asMap();
  }

  
Compares the specified object to this multimap for equality.

Two ListMultimap instances are equal if, for each key, they contain the same values in the same order. If the value orderings disagree, the multimaps will not be considered equal.

  @Override public boolean equals(@Nullable Object object) {
    return super.equals(object);
  }
