A Multimap
that can hold duplicate key-value pairs and that maintains the insertion ordering of values for a given key. See the Multimap
documentation for information common to all multimaps.
The get
, removeAll
, and replaceValues
methods each return a List
of values. Though the method signature doesn't say so explicitly, the map returned by asMap
has List
values.
See the Guava User Guide article on Multimap
.
