[Click] hashmap

Mon Mar 14 08:31:27 EST 2005

Hi Bart,

Have a look at tcprewriter or iprewriter in
<clickdir>/elements/tcpudp/ on usage of bighashmap.
In your .cc file you also need to specify #include <click/bighashmap.cc>
for template purposes, see last lines of above elements' .cc files.

Hope this helps.

Beyers
