说实在,那个主函数是一个很糟糕的写法,没有错误,但是awfully done。
现代软件工程的核心就是:代码易读易改。要做到这点,你的写法就不能违反直觉。
sneaker.Decorate(Alice); <-------------------------
trouser.Decorate(sneaker); 就是这一段看不明白!!!!!
tshirt.Decorate(trouser); 虚函数+覆写函数 咋有递归的感觉
tshirt.Show(); <-------------------------
code里用了英文单词,但是表达的完全不是那个意思,那就是对后来维护的人一种折磨。
Decorator的核心就是一个operation, 经过一条链来处理。这条链是可以动态增加的。
从结果看,你希望达到的效果就是:

Anyone is good at Design Pattern in Java here? Thanks.
As for the decorator pattern, what's the real benefit of using it? In this
example, why not simply let the specific classes, like "Milk/Whip/Sprinkle",
directly extend from the base class or interface "Coffee"?
Thanks.

Halloween decorations中发现中国劳改营的信
Halloween decorations carry haunting message of forced labor

The letter came in a box of Halloween decorations purchased at Kmart, but

Thank you. Still I don't understand how this can be implemented. I had
understood how it's used though.
A typical Decorator design pattern is implemented using composition. The
Decorator and the Component (to be decorated) shall have the same interfaces
. The decorated component can be treated as an original component.
However, in this case, BufferedInputStream and DataInputStream both added
additional functions to FilterInputStream. If a FilterInputStream is
decorated by BufferedInputStream fir

This decorator definition seems not make sense to me.
From your dec. definition, it's obvious it takes two arguments: func, aa. So:
@decorator
def f():
...
is transformed to:
decorator(func, aa)(f)
Your decorator is **got** to take exactly two arguments. If this is the case
, seems that the wrapper is not doing what you want.
Are you trying to do something like:
def decorator(aa):
def outer_wrapper(func):

FileInputStream is the component that's being decorated. It gives a base
component
from which to read bytes.
BufferedInputStream is a concrete decorator. It adds behavior / decorates in
two
ways. It buffers input to improve performance, and also augments the
interface
with a new method readLine() for reading character-based input, a line at a
time.
DataInputStream is also a concrete decorator. It adds the ability to let an
application read primitive java data types from an underlying input strea

They both have the same interface for inputting dada. They both need to perf
orm decoration for the input stream. Since they are both subclasses of Filte
rInputStream, they can be chained together. Their neighbor is specified in t
he constructor. So each of them need to get data from the underlying (or nei
ghbor) input stream and do the specific decoration. Then wait the data to be
read by the next neighbor.

装浴室要买的东西:
Shower的防水底盘,下水和墙壁防水膜,比较受推崇的Schluter的整套kerdi系统在本
地经销商只要$420。4尺的底盘和108尺的防水膜。
类似的系统在floor and decor outlet最便宜的一款要$499,而且是3尺的底盘和53尺
的防水膜。
装墙壁的玻璃马赛克,8毫米厚度的在floor and decor outlet要$8.55一尺,同样8毫
米厚度的在costco订购只有$3.99一尺,不过在costco还要付运费。
所以最后我估计只有地板的大理石会在floor and decor outlet买。

来自主题: JobHunting版 - 说说Decorator那个题
Finery就是Decorator的基础类,作为基础类,必须实现原来class里想要做成链式传递
的function, extend Person就是最容易的选择。如果你用use的关系,链象这个样子:
Decorator1() -> Decorator2() -> Decorator3() -> ....
Decorator1显然只能接受Person, Decorator2和其它的,要接受Finery, 而Finery不继
承Person, 那这条链形式上就不是完全一致的,就没办法随便交换Decorator的次序。

Marble is beautiful, but it takes time and effort for maintenance. So I will
choose big porcelain tiles for shower stall and tub wall surroundings.
For the decorative trim, if installed a little below the shower head (so not
in the spray line), would it almost maintenance free if they are marble (or
travertine)? Handheld shower head will be installed, so I cannot guarantee
that the decorative area is always dry, because my daughter sometimes takes
off the showerhead.

the party theme is "Thomas the Train"
I would like all the decorations stuff having Thomas on it.
I checked Diapers.com. It has birthday party stuff but no Thomas stuff.
On the website, orientaltrading.com, it has Thomas decoration stuff, but too
expensive.

如果你有一个现成的类,然后你想继续开发

怎么办?在这个基础之上额外加一个类
并把新增方法放到这个新增的类里面去
