public interface Shareable

An interface which allows you to put arbitrary objects into a LocalMap.

Normally local maps only allow immutable or copiable objects in order to avoid shared access to mutable state.

However if you have an object that you know is thread-safe you can mark it with this interface and then you will be able to add it to LocalMap instances.

Mutable object that you want to store in a LocalMap should override copy() method.

Use this interface with caution.
