Re: [android-developers] What does the prefix 'm' stand for ?

2010-02-22 Thread Romain Guy 
I myself am not fond of prefixes, especially since languages like Java
already have "this." when you need to distinguish local vars vs
members. Also, modern IDEs highlight fields differently from local
variables.

It does make sense however on a project like Android where not
everybody is necessarily using an IDE. And it's just a coding
convention :)

I use "m_" purely so I don't have to think up different names for my 
method parameters and to avoid things like "this.foo = foo"...it also 
avoids the accidental reference to a local variable when the member was 
intended (or vice versa). Is it awesome? No. But for me, it serves its 
purpose.


The fact that it needs explaining is beside the point. In the end it is 
just a name and whether you understand the convention being used or not 
is irrelevant, it still just functions like a normal name. No different 
than someone naming methods or variables with "_" to indicate something 
special. For the unaware, it's just a name. No understanding is necessary.

p.s. Yeah, I know IDEs will color code member variables, but I'm not 
always in an IDE and generally I don't even notice syntax highlighting 
when I am programming. :-)

Well you probably need to explain many other things to a newbie as well.

Some prefix for member variables is very useful to avoid hiding them with
locales and making it easier to read code to understand how it can impact
state outside of its local scope.  The trouble it adds is so small (just put
an m before the member variable name) that I'd find it hard to consider it
not worth it. :}

I'm one of those guys who think scope prefixes, like "m", are more trouble
than they're worth. The fact that you had to explain it to a newbie makes me

It stands for "member." I believe the use of an "m" prefix with MFC
has nothing to do with the name MFC either, but rather to identify
variables that are class members as opposed to local variables for
instance.

[android-developers] What does the prefix 'm' stand for ?

2010-02-21 Thread Christ 
Hi guys,

I saw many sample codes that each variable contains the 'm' prefix. I
don't know what this m means.
I have two-year experience in MFC. Each variable has 'm' prefix to
tell you that I'm the one variable of MFC component. (m stands for
MFC).
So...can anybody answer me this question?


Regards,
Christ
