public int size()
MultimapNote: this method does not return the number of distinct keys in the multimap,
which is given by keySet().size() or asMap().size(). See the opening section of
the Multimap class documentation for clarification.

Multimaptrue if this multimap contains at least one key-value pair with the key key and the value value.containsEntry in interface Multimap<K,V>containsEntry in class AbstractMultimap<K,V>public java.util.Set<V> get(K key)
SetMultimapkey in this multimap, if any.
Note that when containsKey(key) is false, this returns an empty collection, not null.
Changes to the returned collection will update the underlying multimap, and vice versa.
Because a SetMultimap has unique values for a given key, this method returns a
Set, instead of the Collection specified in the Multimap
interface.
public boolean put(K key, V value)
MultimapSome multimap implementations allow duplicate key-value pairs, in which case put
always adds a new key-value pair and increases the multimap size by 1. Other implementations
prohibit duplicates, and storing a key-value pair that's already in the multimap has no effect.
public boolean putAll(K key, java.lang.Iterable<? extends V> values)
Multimapvalues, all using the same key,
key. Equivalent to (but expected to be more efficient than):
for (V value : values) {
put(key, value);
}
In particular, this is a no-op if values is empty.
public boolean putAll(Multimap<? extends K,? extends V> multimap)
Multimapmultimap in this multimap, in the order returned by
multimap.entries().public java.util.Set<V> replaceValues(K key, java.lang.Iterable<? extends V> values)
MultimapIf values is empty, this is equivalent to removeAll(key).

multimap, if such exists. If multiple key-value pairs in the multimap fit this description,
which one is removed is unspecified.public java.util.Set<V> removeAll(@CheckForNull java.lang.Object key)
SetMultimapkey.
Once this method returns, key will not be mapped to any values, so it will not
appear in Multimap.keySet(), Multimap.asMap(), or any other views.
Because a SetMultimap has unique values for a given key, this method returns a
Set, instead of the Collection specified in the Multimap
interface.
