root/i-scream/experimental/server/ACL/ACLTest.java
Revision: 1.5
Committed: Mon Dec 31 01:49:13 2001 UTC (22 years, 10 months ago) by tdb
Branch: MAIN
Changes since 1.4: +10 -1 lines
Log Message: 
Some significant internal changes. It should be noted that this code is still in
the debugging stage, and thus contains lots of println's :-)
The most obvious change is that when adding a rule we try to determine if it's
and IP address given as the expression. If it is, we store this in a short[] in the
ACLRule inner class. Then when performing a check we look to see if it's an
IP address rule, and then do a special check for IP addresses - which is much
more efficient than comparing two strings. We have also halved the checks
done by only comparing a rule to either the name or IP, rather than both.
