Method Detail

consolidate

void consolidate()

clear

void clear()

clears the forwarding table. Removes every association of predicates and interfaces. After the execution of this method, the forwarding table is ready to be rebuilt from scratch.

match

void match(Message m,
         MatchMessageHandler p)

matches a message against the proedicates in the table. For each matching predicate, this method delegates the execution of a specific action to the given match handler.

MatchMessageHandler

match

void match(Message m,
         MatchHandler p)

matches a message against the proedicates in the table. For each matching predicate, this method delegates the execution of a specific action to the given match handler.

See Also:

MatchHandler

ifconfig

void ifconfig(java.lang.Object ifx,
            Predicate p)
              throws BadConstraintException

associates an interface with a predicate This is the main method that builds the forwarding table. It associates an interface object with a predicate. Notice that this forwarding table is a dictionary-type data structure, which means that this method may be called only once for each inteface object. If you need to modify the predicate associated with an interface, you must rebuild the entire forwarding table.

Throws:

BadConstraintException
