Constructor & Destructor Documentation

template<class A >

RIBVarRW< A >::RIBVarRW ( IPRouteEntry< A > & route )

Parameters:

route route to filter and possibly modify.

template<class A >

void RIBVarRW< A >::read_route_nexthop ( IPRouteEntry< A > & r ) [private]

Specialized template to read nexthop and ip address.

If it is a v4 specialization, v6 addresses are set to null and vice-versa.

Parameters:

r	route from which to read addresses.

template<class A >

Element * RIBVarRW< A >::single_read ( const Id & id ) [virtual]

Read of a variable.

The VarRW needs to read a particular element. This may return NULL indicating ElemNull---i.e. variable not present in THIS route.

Parameters:

id	the id of the variable.

Implements SingleVarRW.
