Re: [CFCDev] cfc or code better?

[Nathan Dintenfass]

You have some kind of struct lookup inside your CFC, I suspect.  The 
performance issues associated with the differences you are talking about 
are not worth worrying about for 99% of applications.  You would be much 
better off building your code to be manageable and easy to debug than 
worrying about a millisecond here and there -- you can then go back and 
address serious bottlenecks if they occur (in your case, it doesn't 
sound like you have one).

Stick with whatever code construct is the most semantically descriptive 
and best encapsulated and you will rarely go wrong.  Making choices 
about code to save a few milliseconds is typically a path to badness 
overall.

hola peeps.
i have a cfc, that simply takes an integer that represents a heading,
and turn that into a value that i display based on the return.
i put the cfc in the session scope:
<cfset session['COG'] = createObject("component","cfc.cogToDirection") />
and then just hit it like this...
#session['COG'].COGToDirection(getThis.COG[i])#
and display all in the same line.
now, in my debugging output i see 0ms.  but i know that there is no
such thing.  there are milliseconds attached, im sure, and enough of
those, well, you know... equal a second.  regardless... do you think,
as a preference, that i would be better off with a simple
cfswitch/cfcase section of code that does this, rather than hit the
cfc?
thanks.
