fun entries(): ImmutableSet<Map.Entry<K, V>>? { val result: ImmutableSet<Map.Entry<K, V>>? = entries return if (result == null) EntrySet<K, V>(this).also { entries = it } else result }
Returns an immutable collection of all key-value pairs in the multimap . Its iterator traverses the values for the first key , the values for the second key , and so on .
