    • Set with class: TimeValue
    • Underlying type: Time
    • Initial value: +0.0ns
    • Flags: construct write read
  • StopTime: Time at which the application will stop
    • Set with class: TimeValue
    • Underlying type: Time
    • Initial value: +0.0ns
    • Flags: construct write read

No TraceSources are defined for this type.

Member Function Documentation

void ns3::Application::DoDispose ( void  )
protectedvirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

Reimplemented in ns3::UdpEchoClient, ns3::OnOffApplication, ns3::UdpTraceClient, ns3::Ping6, ns3::PacketSink, ns3::Radvd, ns3::EpsBearerTagUdpClient, ns3::BulkSendApplication, ns3::UdpServer, ns3::UdpClient, ns3::EpcEnbApplication, ns3::EpcSgwPgwApplication, ns3::V4Ping, and ns3::UdpEchoServer.

void ns3::Application::DoInitialize ( void  )
protectedvirtual

This method is called only once by Object::Initialize. If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.

Reimplemented from ns3::Object.

void ns3::Application::SetNode ( Ptr< Node node)
Parameters
nodethe node to which this Application object is attached.

Definition at line 110 of file application.cc.

References NS_LOG_FUNCTION.

void ns3::Application::SetStartTime ( Time  start)

Specify application start time.

Parameters
startStart time for this application, relative to the current simulation time.

Applications start at various times in the simulation scenario. The Start method specifies when the application should be started. The application subclasses should override the private "StartApplication" method defined below, which is called at the time specified, to cause the application to begin.

Definition at line 68 of file application.cc.

References NS_LOG_FUNCTION.

void ns3::Application::SetStopTime ( Time  stop)

Specify application stop time.

Parameters
stopStop time for this application, relative to the current simulation time.

Once an application has started, it is sometimes useful to stop the application. The Stop method specifies when an application is to stop. The application subclasses should override the private StopApplication method, to be notified when that time has come.

void ns3::Application::StartApplication ( void  )
privatevirtual

Application specific startup code.

The StartApplication method is called at the start time specified by Start This method should be overridden by all or most application subclasses.

Reimplemented in ns3::UdpEchoClient, ns3::OnOffApplication, ns3::UdpTraceClient, ns3::Radvd, ns3::Ping6, ns3::PacketSink, ns3::EpsBearerTagUdpClient, SimpleSource, ns3::BulkSendApplication, ns3::UdpServer, ns3::UdpClient, ns3::UdpEchoServer, ns3::V4Ping, and ns3::SocketWriter.

void ns3::Application::StopApplication ( void  )
privatevirtual

Application specific shutdown code.

The StopApplication method is called at the stop time specified by Stop This method should be overridden by all or most application subclasses.

Reimplemented in ns3::UdpEchoClient, ns3::OnOffApplication, ns3::UdpTraceClient, ns3::Radvd, ns3::Ping6, ns3::PacketSink, ns3::EpsBearerTagUdpClient, SimpleSource, ns3::BulkSendApplication, ns3::UdpServer, ns3::UdpClient, ns3::UdpEchoServer, ns3::V4Ping, and ns3::SocketWriter.
