DoubleKeyMap

Sometimes we need to map a key to a value but key is two pieces of data. This nested hash table saves creating a single key each time we access map; avoids mem creation.

class DoubleKeyMap (

) {

V[K1][K2] data;

V put(K1 k1, K2 k2, V v);

Nullable!V get(K1 k1, K2 k2);

V[K2] get(K1 k1);

V[] values(K1 k1);

K1[] keySet();

K2[] keySet(K1 k1);

}
