Returns an immutable multimap containing the given entries, in order. Repeated occurrences of an entry (according to Object.equals(java.lang.Object)) after the first are ignored.

public static <K,V> ImmutableSetMultimap<K,V> of(K k1, V v1, K k2, V v2, K k3, V v3, K k4, V v4, K k5, V v5)
Returns an immutable multimap containing the given entries, in order. Repeated occurrences of an entry (according to Object.equals(java.lang.Object)) after the first are ignored.
public static <K,V> ImmutableSetMultimap.Builder<K,V> builder()
Returns a new ImmutableSetMultimap.Builder.
public static <K,V> ImmutableSetMultimap<K,V> copyOf(Multimap<? extends K,? extends V> multimap)
Returns an immutable set multimap containing the same mappings as multimap. The generated multimap’s key and value orderings correspond to the iteration ordering of the multimap.asMap() view. Repeated occurrences of an entry in the multimap after the first are ignored.
Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
NullPointerException - if any key or value in multimap is null@Beta public static <K,V> ImmutableSetMultimap<K,V> copyOf(Iterable<? extends Map.Entry<? extends K,? extends V>> entries)
Returns an immutable multimap containing the specified entries. The returned multimap iterates over keys in the order they were first encountered in the input, and the values for each key are iterated in the order they were encountered. If two values for the same key are equal, the first value encountered is used.
NullPointerException - if any key, value, or entry is nullpublic ImmutableSet<V> get(@Nullable K key)
Returns an immutable set of the values for the given key. If no mappings in the multimap have the provided key, an empty immutable set is returned. The values are in the same order as the parameters used to build this multimap.
public ImmutableSetMultimap<V,K> inverse()
Returns an immutable multimap which is the inverse of this one. For every key-value mapping in the original, the result will have a mapping with key and value reversed.
Because an inverse of a set multimap cannot contain multiple pairs with the same key and value, this method returns an ImmutableSetMultimap rather than the ImmutableMultimap specified in the ImmutableMultimap class.

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.
public boolean isEmpty()
MultimapReturns true if this multimap contains no key-value pairs. Equivalent to size() == 0, but can in some cases be more efficient.
public boolean containsEntry(@Nullable Object key, @Nullable Object value)
MultimapReturns true if this multimap contains at least one key-value pair with the key key and the value value.
containsEntry in interface Multimap<K,V>public boolean equals(@Nullable Object object)
MultimapCompares the specified object with this multimap for equality. Two multimaps are equal when their map views, as returned by Multimap.asMap(), are also equal.
In general, two multimaps with identical key-value mappings may or may not be equal, depending on the implementation. For example, two SetMultimap instances with the same key-value mappings are equal, but equality of two ListMultimap instances depends on the ordering of the values for each key.
A non-empty SetMultimap cannot be equal to a non-empty ListMultimap, since their Multimap.asMap() views contain unequal collections as values. However, any two empty multimaps are equal, because they both have empty Multimap.asMap() views.
public int hashCode()
The hash code of a multimap is defined as the hash code of the map view,
as returned by Multimap.asMap().
public String toString()
toString on the map returned by Multimap.asMap().
