Conventional specifications for object-oriented (OO) programs must adhere to behavioral
subtyping in support of class inheritance and method overriding. However, this requirement …

Object invariants define the consistency of objects. They have subtle semantics because of
call-backs, multi-object invariants and subclassing. Several visible-state verification …

Modular reasoning about class invariants is challenging in the presence of collaborating
objects that need to maintain global consistency. This paper presents semantic …

This paper contributes a technique that expands the set of object invariants that one can
reason about in modular verification. The technique uses history invariants, two-state …

Abstract We propose Considerate Reasoning, a novel specification and verification
technique based on object invariants. This technique supports succinct specifications of …

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 …

Relationships capture the interplay between classes in object-oriented programs, and
various extensions of object-oriented programming languages allow the programmer to …

A verifying compiler automatically verifies the correctness of a source program before
compiling it. Founded on the definition of the source language and a set of rules (a …

Class invariants are both a core concept of object-oriented programming and the source of
the two key open OO verification problems: furtive access (from callbacks) and reference …

The correctness of object-oriented programs relies on object invariants. A system for
verifying such programs requires a systematic method for coping with object invariants that …
