checkImplementation()

Check the consistency of internal state, and raise exception if not OK.

 public abstract void checkImplementation() throws ImplementationError

Check the consistency of internal state, and raise exception if not OK. These should be `best-effort' checks. You cannot always locally determine full consistency, but can usually approximate it, and validate the most important representation invariants. The most common kinds of checks are cache checks. For example, A linked list that also maintains a separate record of the number of items on the list should verify that the recorded count matches the number of elements in the list.

This method should either return normally or throw:

Throws: ImplementationError

if check fails
