Comment #1 on issue 199 by [email protected]: Docs explain SCCP rule
ordering mechnism
http://code.google.com/p/jss7/issues/detail?id=199
When user defines Rules, a comparison function imposes ordering on
collection of SCCP Rules
based on the GT digits. The sorting algo is as defined bellow
1) GT digits having no wildcard (* or ?) is always on top of the list.
Between
two GT digits, both having no wildcards, one with shortest length is on top
of list. For example Digit1 "123456" will be above Digit2 "1234567890" will
be above Digit3 "999/*
2)GT digits having wildcard ? is always above digits having wildcard *. For
example Digit1 "800/????/9" will be above Digit2 "999/*
3) Between two GT digits both having wildcard ?, one with least number of
wildcard ? is on top of list. For example Digit1 "800/????/9" is above
Digit2
"800/?????/9"
4) Between two GT digits both having equal number of wildcard ?, the digit
who's
first appearance of ? is after other, is on top of list. For example
between
Digit1 "80/??/0/???/9" and Digit 2 "800/?????/9", Digit2 is above Digit1
When comparison of rule is done in translation, comparing always starts
from top of list.
