Clears the forwarding table.
This method removes all the associations from the forwarding table and releases allocated memory. After a call to this method, the forwarding table is ready to be configured with ifconfig().

Clears the forwarding table.
This method removes all the associations from the forwarding table recycling the allocated memory. After a call to this method, the forwarding table is ready to be configured with ifconfig().

Implements siena::BDDBTableBase.
Associates a predicate to an interface.
This is the method that constructs the forwarding table. This method must be called once for each interface, after the forwarding table is constructed or after it has been cleared. Using this method twice on the same interface without clearing the forwarding table has undefined effects.

Processes a message, calling the output() function on the given MatchHandler object for each matching interface.
Matches a message against the predicates stored in the forwarding table. The result is processed through the MatchHandler passed as a parameter to this function.
Notice that the forwarding table must be consolidated by calling siena::ForwardingTable::consolidate() before this function is called.
