package inet.applications.tcpapp;

//
// This module hosts TCP-based server applications. It dynamically creates
// and launches a new "thread" object for each incoming connection.
//
// Server threads should be subclassed from the TCPServerThreadBase
// C++ class, registered in the C++ code using the Register_Class() macro,
// and the class name should be specified in the serverThreadClass
// parameter of TCPSrvHostApp. The thread object will receive events
// via a callback interface (methods like established(), dataArrived(),
// peerClosed(), timerExpired()), and can send packets via TCPSocket's send()
// method.
//
// Example server thread class: TCPGenericSrvThread (in the C++ documentation only).
//
// IMPORTANT: Before you try to use this module, make sure you actually need it!
// In most cases, TCPGenericSrvApp and GenericAppMsg will be completely
// enough, and they are a lot easier to handle. You'll want to subclass your
// client from TCPGenericCliAppBase then; check TelnetApp and TCPBasicClientApp
// for examples.
//
// Compatible with both IPv4 and IPv6.
