2009年9月19日 · Design by contract/programming by contract can help development greatly by explicitly documenting the conditions for a function. Just the documentation can be a help without even making it into (compiled) code. Where feasible I recommend defensive - checking every condition. BUT only for development and debug builds.

The contract of a class or interface, in Java or any other OO language, generally refers to the publicly exposed methods (or functions) and properties (or fields or attributes) of that class interface along with any comments or documentation …

2008年9月23日 · When programming by contract a function or method first checks whether its preconditions are fulfilled, before starting to work on its responsibilities, right? The two most prominent ways to do these checks are by assert and by …

2018年12月11日 · I'm interested in studying the recently accepted contract programming for C++20 for learning and investigation purpose. As I'm looking around for compiler support, I'm disappointed to not find any. Both gcc and clang are quite clear they do not support this feature within their --std=c++2a mode.

2013年4月10日 · The service contract specifies what operations the service supports. Or in what format data has to be passed : A data contract is a formal agreement between a service and a client. Also interface sometimes is called contract - because it is exactly it: binding agreement on what can be called and how.

2010年5月19日 · In Programming, an interface defines what the behavior a an object will have, but it will not actually specify the behavior. It is a contract, that will guarantee, that a certain class can do something. Consider this piece of C# code here:

2008年10月20日 · A contract is the implicit agreement you make between users and implementers of a class or interface. For instance, preconditions and postconditions (invariants are usually a contract within the class' implementation - generally, things like the relation between internal members don't need to be exposed).

2011年10月30日 · Programming by contracts is a modern trend in .NET, but what about libraries/frameworks for code contracts in PHP? What do you think about applicability of this paradigm for PHP? Googling for "code contracts php" gave nothing to me. Note: by "code by contract", I mean Design by contract, so it has nothing to do with .NET or PHP interfaces.

2008年11月4日 · C# 4.0 Code Contracts. Microsoft has released a library for design by contract in version 4.0 of the .net framework.

2009年1月27日 · Design-by-contract and test-driven development are not mutually exclusive. Bertrand Meyer's book Object Oriented Software Construction, 2nd Edition doesn't say that you never make mistakes. Indeed, if you look at the chapter "When the contract is broken", it discusses what happens when a function fails to accomplish what its contract states.
