Definition: nstime.h:103
Smart pointer class similar to boost::intrusive_ptr.
Definition: ptr.h:73
static void PrintRoute(Ptr< Node > source, Ipv4Address dest, Ptr< OutputStreamWrapper > stream, Time::Unit unit=Time::S)
prints the routing path for the source and destination.
void AggregateObject(Ptr< Object > other)
Aggregate two Objects together.
Definition: object.cc:252
ObjectFactory m_agentFactory
Object factory.
#define NS_ASSERT(condition)
At runtime, in debugging builds, if this condition is not true, the program prints the source file...
Definition: assert.h:67
Helper class that adds Nix-vector routing to nodes.
void SetTypeId(TypeId tid)
Set the TypeId of the Objects to be created by this factory.
Ipv4NixVectorHelper()
Construct an Ipv4NixVectorHelper to make life easier while adding Nix-vector routing to nodes...
Ipv4NixVectorHelper * Copy(void) const
Ptr< Object > Create(void) const
Create an Object instance of the configured TypeId.
void PrintRoutingPathAt(Time printTime, Ptr< Node > source, Ipv4Address dest, Ptr< OutputStreamWrapper > stream, Time::Unit unit=Time::S)
prints the routing path for a source and destination at a particular time.
Nix-vector routing protocol.
Unit
The unit to use to interpret a number representing time.
Definition: nstime.h:109
Access to the IPv4 forwarding table, interfaces, and configuration.
Definition: ipv4.h:76
Ptr< T > GetObject(void) const
Get a pointer to the requested aggregated Object.
Definition: object.h:470
