发帖数: 3989 | 3 呵呵,, 这个其实很难的.
比如single responsibility ，大家都认为很容易，但在实际上没有TEAM会真正做好。
而且每个人对singled的界定不一样。
OpenClose， 估计刚学oo编程的人就只到。但实际什么时候该用，如何用，还是简单的
if switch就能满足。
至于后面的。。就更难了。
学习一点用IOC的实例可能会帮助理解。但实际工作中用IOC需要整个team都能明白才行。
我觉得想进行solid的实践，从学习写unit test，并用一些mock工具比如moq， 并
refactor你现有程序开始， 比较实际可行。 |

发帖数: 1879 | 17 I like Eclipse very much. If you write a not so small Java project,
refactoring/reference searching is vital. This reason plus the fact
that it is free, makes it hard to be beat.
JB seems to be very hard to configure properly, and it is not free
(the free version is old and slow w/ poor GUI).
The best Java IDE is IntelliJ IDEA, current version is 4.0. If you
have used it, you will see why it is the best. It is better than
Eclipse in every single area, but unfortunately it is very costly

发帖数: 1879 | 24 I think that for your problem:
1. Break them down into categories and have an object that represent
each category (and thus put attributes in that category only).
Then, you pass categories around.
Rarely you would create new categories of data, so, adding new
parameter only affect the data structure of categories object per se,
not any signatures of function calls. Thus saving you the refactoring
trouble.
2. Depending whether or not you clone the category object often, as well |

If A should run before C is part of the logic flow, shouldn't you
have some _code_ capturing/enforcing it, instead of just documenting
it?
I would also rely heavily on rigrous testing, which always goes
hand in hand with active refactoring. "A has run" can be a precondition
for C's test cases.
Also, it would never hurt to throw in a couple of asserts at
the beginning of C if it's so important.
While it certainly needs to be well documented, documentation, by
its nature, is explanatary rather th |

发帖数: 14569 | 27 How would you write code to enforcing this logic --
A depends on XML Document object "doc" be untouched;
C will modify some nodes within "doc"
so now A should run before C
After refactoring, A become A1 + A2 + A3, actually, only A2 needs "doc" be
untouched.
And C become C1 + C2, only C2 will modify "doc".
So now, A1, A3, C1's running order is not important any more. But A2 needs to
run before C2.
I find this kind of situation happens a lot when working in a huge project.

Hmm, refactoring does not change logic flow, right? Say, even you
split C to C1, C2, and C3. What used to be:
C(target);
would simply be replaced with:
C1(target);
C2(target);
C3(target);
I see your point in general. I guess I would still rely on regression testing
to ensure the logic isn't changed. In this case, C doesn't really
require A to be run before itself, because it doesn't really rely on
anything A puts in target. It's the logic block that uses A and C needs
to be regression test |
