Is there a corresponding immutable enumMap in guava?

I was just wanted to provide an example now that ImmutableEnumMap is in Guava 14.0, because it's a package-private class, so you can't do ImmutableEnumMap.of(). You have to do Maps.immutableEnumMap() instead.

private final ImmutableMap<MyEnum, String> myEnumMap = Maps.immutableEnumMap(ImmutableMap.of(
        MyEnum.A,   "A",
        MyEnum.B,   "B",
        MyEnum.C,   "C"
        ));

Not sure if there's a more natural syntax.


Guava contributor here.

Guava doesn't currently have an ImmutableEnumMap variant, but if it did, it would probably just be a wrapper around an EnumMap. (That said, slightly better immutable implementations are possible.)

EnumMap will perform better than the basic ImmutableMap, in any event; it's difficult or impossible to beat.

(I'll file an issue to investigate adding an ImmutableMap variant for enum key types, though.)


Update: Guava 14 adds Maps.immutableEnumMap().
