/**
|

* An immutable {@link Multimap}. Does not permit null keys or values.
|

*
|
||||
* <p>
|
||||
* Unlike {@link Multimaps#unmodifiableMultimap(Multimap)}, which is a
|
||||
* <i>view</i> of a separate multimap which can still change, an instance of
|
||||
* {@code ImmutableMultimap} contains its own data and will <i>never</i> change.
|
||||
* {@code ImmutableMultimap} is convenient for {@code public static final}
|
||||
* multimaps ("constant multimaps") and also lets you easily make a "defensive
|
||||
* copy" of a multimap provided to your class by a caller.
|
||||
*
|
||||
* <p>
|
||||
* <b>Note:</b> Although this class is not final, it cannot be subclassed as it
|
||||
* has no public or protected constructors. Thus, instances of this class are
|
||||
* guaranteed to be immutable.
|
||||
*
|
||||
* <p>
|
||||
* In addition to methods defined by {@link Multimap}, an {@link #inverse}
|
||||
* method is also supported.
|
||||
*
