Specification and verification of object oriented programs usually features in some capacity the concept of an object invariant, used to describe the consistent states of an object. Unavoidably, an objects invariant will be broken at some points in its lifetime, and as a result, invariant protocols have been suggested, which prescribe the times at which object invariants may be broken, and the points at which they have to be re-established. The fact that currently available invariant protocols do not handle well some known examples, together with the fact that object invariants and invariant protocols can largely be encoded through methods pre- and post- conditions has recently raised the question of whether they still have a role to p...
