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.

public ImmutableSetMultimap<V,K> inverse()
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.

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().
