BGPVarRW (const string& name)
| BGPVarRW |
This varrw allows for routes to remain untouched even though they are
filtered. This is useful in order to check if a route will be accepted
or rejected, without caring about its modifications.
Parameters:
name | the name of the filter to print in case of tracing.
|
[virtual]
void attach_route (const InternalMessage<A>& rtmsg, bool no_modify)
| attach_route |
Attach a route to the varrw.
Parameters:
rtmsg | the message to filter and possibly modify.
|
no_modify | if true, the route will not be modified.
|
Caller owns the message [responsible for delete].
Calling multiple times will always return the same message, not a copy.
Returns: the modified message. Null if no changes were made.
Element* single_read (const Id& id)
| single_read |
Reimplemented from SingleVarRW.
void single_write (const Id& id, const Element& e)
| single_write |
Reimplemented from SingleVarRW.
void end_write ()
| end_write |
Reimplemented from SingleVarRW.
bool modified ()
| modified |
If a route is modified, the caller may obtain it via the filtered_message
call.
Returns: true if route was modified. False otherwise.
string more_tracelog ()
| more_tracelog |
[virtual]
Output basic BGP specific information.
Returns: BGP trace based on verbosity level returned from trace().
Element* read_neighbor ()
| read_neighbor |
[virtual]
Reads the neighbor variable. This is different on input/output branch.
Returns: the neighbor variable.
Element* read_neighbor_base_cb ()
| read_neighbor_base_cb |
Callback wrapper used to call the virtual read_neighbor() method.
Returns: the neighbor variable.
