Re: [CFCDev] CFC size

[Mike Chabot]

OK. I am not concerned so much about "number of lines" as I am about 
complexity. A lot of lines are added to my code due to switch blocks and 
comments. However, there are some functions that are quite complex. The 
specific CFC I am working with is a employee's timecards CFC (not an 
employee CFC). There are functions for retrieving the current timecard, 
going to the next, going to the previous, getting information out of the 
database, adding, updating, deleting, undoing, validation routines, 
rounding functions, many sub-functions for date calculations, plus many 
more. I suppose one way for me to break it down into a timecards CFC which 
contains an array of individual timecard CFCs. I guess my question is at 
what point do I start considering this? I am also concerned about the RAM 
usage. What is the impact on RAM usage of having a function inside of every 
instance of a CFC versus having a function inside of a single custom tag? 
For example, if I break down the CFC into a CFC representing the timecards 
array and a CFC representing each timecard, am I actually doing a 
disservice since the number of CFC instances, and the number methods 
repeated in RAM, will now be much greater?

The sense I am getting from the responses people have given is that CFCs 
are not scalable the same way a typical function library would be scalable. 
Is this the general feeling?

In CF5, if I saw a file that had more than 2000 lines of code, my first 
impression would be that the code is poorly designed and that it could 
probably be broken down using custom tags and cfincludes. However, with 
CFCs, all of these custom tags and cfincludes are essentially bundled 
together in a single file, so I have to reset my sense of what is good and 
what is bad.

Does anyone know of a good way to determine how much RAM each CFC is using? 
How about even some rule of thumb method, such as 1 byte of variable length 
= 1 byte of RAM? How will I know when the "Maximum JVM Heap Size" is reached?

Thank you,
Mike Chabot
