发帖数: 1297 | 1 Yes, I'm pretty sure this is a question.
Factory pattern is not based on reflection, it's more like you defined
interface and some basic/abstract class or data model. The implementation
implements those interfaces. You don't really need to use reflection to
invoke methods and so on. The only part that may relate to reflection is
Class.forName. But after that, every thing is just interface API call
directly, no dynamic.
Reflection more like dynamic programming, you invoke method not really from

Reflection is a significant part of growth. At Westmont Junior High School,
in Westmont, Illinois, my 8th grade Literacy classes took the PARCC test
this past March. My amazing two 8th grade Literacy teachers understood
there was an interesting lesson within the ongoing discussions about PARCC

发帖数: 34805 | 3 I don't know what you are smoking. But I don't think you can convince anyone
Class.forName().newInstance() is not a reflection call.
Factory Pattern doesn't have to use reflection. True, but only reflection
can achieve the decoupling that separates the factory from knowing what it's
gonna create. This is a huge advantage over those languages that do not
have reflection.
It's not about statistics. This one reflection call is critical in framework
design.

电影电视，没有太多感觉，于是也觉得瑞士好啊。说我以后也一定要去看。不过看了阿
甘正传后，喜欢阿甘和珍妮的故事，尤其是他们在Reflecting Pool重逢相拥的时候。
也是我也想，以后也一定要去看Reflecting Pool。
后来刚来美国半年，我就去了D.C.，怀着高兴的心情，绕着池子走了一圈再一圈。稀稀

啊。还在琢磨阿甘是在哪个方位和珍妮重聚的，呵呵。后来第二次去欧洲的时候，就住
在日内瓦湖旁边。轻轻地在湖水里头洗了下手，赶了岸边的鸟儿，喀嚓让岸边的情侣给
俺拍了几张照片。
现在隔D.C.近了，去的机会也多了。我对博物馆什么的不感冒，去的很少，但每次都喜

I erect a harp by the mirror lake.
In the mirror I gaze at her grace,
And beauty that ain’t empty or fake.
When autumn breeze wrinkles her face,
I hear fallen leaves pluck her string.
And see tender green decorate her reflection.
Harp sings a song of mesmerizing spring,
Till I tie autumn with affection.

"Tip: An access restriction exists which prevents reflective invocation of
constructors which normally would not be accessible via direct invocation. (

发帖数: 985 | 17 computer science的一个重要的思路就是
add (yet) a(nother) layer of indirection,
Java的长处就在于JVM这层indirection，
而Reflection以及AOP存在的原因
就在于发挥这层indirection,
Reflection就可以让code自己去分析发现class/method/parameters etc.
并且invoke methods when necessary. |
|
r*****s
发帖数: 985 | 18 基于这个例子，
比如现在定义好了这个JDBC的API，
有了Reflection，
无论底下library是MySQL的也好，
Oracle的也好，
version不同也没关系，
只要用Reflection找到那个API的method，
直接invoke就好了，
别说不用像C/C++那样重新build，
你写code的时候底下用和runtime时不同的library都没关系。

发帖数: 34 | 20 Java Reflection看起来容易，但是用起来不容易，功力不到去用，那肯定是用错了
1 首先这玩意肯定是业务无关的，纯粹用来写框架用，谁要是写业务逻辑用了反射立
马打回去重写
2 Java的Object Oriented世界讲究面向接口编程，力图实现各种“高聚合低耦合”的
类，尽可能提高类的可重用性。
3 组件与组件之间只通过接口通讯，这样就和具体实现解耦，解耦的方式正是通过文
件配置
4 xml文件配置里，无论是class还是property还是任何别的东西，都是String来表达
的，JVM通过什么方式将String转化成Class和Object，就是Java Reflection了 |

发帖数: 587 | 21 high hands:
I have a question on Object Oriented design patterns that reflect context
change. I want to know if there are design patterns available
for reflecting behavioral change in an Object, or in another words, the
object can assume several "states", each with distinct behavior depending
in internal or external input.
Is the calculation of a series of "state" change expensive computationally?

发帖数: 313 | 22 you have a lot to consider actually. think about the penetration
depth. in reflectivity mode the penetration depth will be small, what
will that happen if your layer is think enough?
I will also argue that the reflective indix is not determined by
the whole sample. Think about the mostly used box model to fit macromolecular
data, the electron densities are not the same from box to box. |
