* Class ns3::Application can be used as a base class for ns3 applications.
|
|
* Applications are associated with individual nodes. Each node
|
|
* holds a list of references (smart pointers) to its applications.
|
|
*
|
|
* Conceptually, an application has zero or more ns3::Socket
|
|
* objects associated with it, that are created using the Socket
|
|
* creation API of the Kernel capability. The Socket object
|
|
* API is modeled after the
|
|
* well-known BSD sockets interface, although it is somewhat
|
|
* simplified for use with ns3. Further, any socket call that
|
|
* would normally "block" in normal sockets will return immediately
|
|
* in ns3. A set of "upcalls" are defined that will be called when
|
|
* the previous blocking call would normally exit. THis is documented
|
|
* in more detail Socket class in socket.h.
|
|
*
|
|
* The main purpose of the base class application public API is to
|
|
* provide a uniform way to start and stop applications.
