guava/collections, how does one specify the iteration order in an ImmutableMap

[fishtoprecords]

From the javadocs:
An immutable, hash-based Map with reliable user-specified iteration
order.

This is just what I want. How do I specify the iteration order? I
don't see anywhere to specify a Comparator or similar thing.

Thanks

Eep.

What we mean by "user-specified" is "it can be whatever order you want it to be"; in other words, whatever order you provide the entries to us in the first place, that's the order we use.  If a Comparator is choosing the order instead, that's actually an ImmutableSortedMap.

HTH.

OK, so the order its put in, that's an order I can control.

I assume I need to call a suitable Builder in the order I want, rather than just dumping in a HashMap for an ImmutableCopy.

Exactly, ImmutableMap.Builder.  Tiny maps (up to five entries) can use ImmutableMap.of().

You can also copy a TreeMap or LinkedHashMap that have the desired order.
