HashMap equivalent in trove?

Question

I have just learned about trove library and how it's more memory efficient than JDK's Maps. I was previously using a hash map to store totalSize = 2^N double array entries, as follows:

final Map myTable = new HashMap(totalSize);

I was wondering if there is an equivalent class in Trove? or if there is a way to use Class TIntDoubleHashMap that makes the same collection as myTable HashMap?

I would appreciate any help/suggestion.

That works but I'm not sure if it is any different from jdk hashmap ? since it has to use Integer rather than int. I'm switching to trove to be able to work with primitive types. — PyPhys, Jan 15 '15 at 04:52

A double[] is, in fact, an object, so you should probably just use TIntObjectHashMap<double[]>.
