inverse
ImmutableBiMap<V,K> inverse()Description copied from interface:BiMap
Returns an inversed view of this BiMap, where the associations are in the direction of this bimap's values to keys. -
flip
ImmutableSetMultimap<V,K> flip()Description copied from interface:MapIterable
Given a map from Domain->
Range return a multimap from Range->
Domain. We chose the name 'flip' rather than 'invert' or 'transpose' since this method does not have the property of applying twice returns the original.Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However, since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus, we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.

has a list ofAddress
objects. Take the followingFunction
