enable the container to intercede in all client calls on the session bean. The

并取的该表的一个列表Collection
该Collection元素就是该CMP
并返回此Collection到JSP客户端
在JSP客户端
肯定要逐项打开Collection中的CMP
并显示这些数据
这样不是在JSP使用了CMP了么？
这算起来也不符合设计模式吧？
这些CMP占不占数据库连接呢？ |

发帖数: 34805 | 40 Well, I joined this company, and all the instances

than convention. |

发帖数: 2416 | 41 Well if all of them start with m_, at least they are consistent. 8-)
m_* originated from MSVC practice, I think.
For a couple of years I had all of my instance variables starting
with _, which actually makes the code much more readable if
you have to read the code in an editor without syntax highlight. |

发帖数: 34805 | 42 It's maybe slightly more readable, but a headache on refactoring.
Think of a dumb value class, with IDE like eclipse you only need
to put down instance names and generate getter/setters out of it.
Now some manual changes are inevitable. You don't want to live with
function name like getM_blah |

Oh no no, I was just talking about _starting_ instance variables with "_"
to distinguish them from local variables, not having "_" in the middle.
I totally agree with you. It's pointless and calling for trouble to do that.
And it's not even necessary to have starting _'s with modern IDEs. |

发帖数: 4889 | 45 this is c++ convention. java people don't use it. |

发帖数: 1879 | 46 nope.
It is pretty common to have instance variable prefixes. It prevent
one obvious error:
var = var
when it should be
this.var = var
this. is pretty painful to type and not everyone do it.
Particularly when you are quick viewing a source code, having m_ is
very helpful to distinguish instance variables from params.
Eclipse / IDEA all support prefixes. |
|
g*****g
发帖数: 34805 | 47 when you do var = var, Eclipse gives you a warning.
this.var isn't really that difficult to type with modern IDE.
The problem with prefix is refactoring, it just doesn't follow
java bean convention for example. Many convention over configuration
libraries now count on the right instance name to do the magic via
annotation. |

发帖数: 4889 | 48 in 水木社区，java people believe that m_ is unneccesary and reduces
readability. they think when there is a this.var = var, you shold always
type this. explicitely to inhance readability.
and they said that good IDEs, like IDEA will automatically show member
variable and local variable in different colors, there is totally no need to
use m_. and they also believe that the extra m_ makes the automatic
completion feature slower to show up (you need to type m_ then another
character to trigger this) |

发帖数: 4889 | 49 i think for member variable known to outside(e.g. with setXX and getXX
