off-heap-hashmap

A Java HashMap where the values are kept off the heap in a Memory Mapped File.

I created this Map implementatio for caches where the Value objects a really BIG and just sit on your heap doing not much. By keeping them off the heap, you can have a JVM with a smaller heap size which may be better.

I did this for two reasons:

1. as a challange to myself
2. as a prototype to show it can be done

For now it's just a toy project. If anyone in interested, I will clean it up, add tests etc.
