* This file contains rewrites of several functions, from both interfaces.inc

28
|
* and interfaces_assign.php. The general purpose of these rewrites is not
|
|
29
|
* necessarily to be faster in and of themselves, though they may be, but to
|
|
30
|
* replace functions called multiple times with a function that's called only
|
|
31
|
* once. This results in a significant speedup because there are far fewer
|
|
32
|
* function calls, fewer loops and suchlike. It does, however, increase memory
|
|
33
|
* usage somewhat, but it shouldn't be significant in the grand scheme of things.
|
|
34

|
|
35
|
*
|
|
36
|
* Functions in this file may not require/use parameters when called, however
|
|
37
|
* in most cases they will accept parameters as per their original forms, for

38
