Detailed Description

Abstract class that serves one client of TrikServer.

Meant to work in separate thread. Creates its own socket and handles all incoming messages.

Constructor & Destructor Documentation

Connection::Connection ( Protocol  connectionProtocol, Heartbeat  useHeartbeat  )

explicit

Constructor.

Parameters

connectionProtocol	- protocol used by this connection.
useHeartbeat	- use or don't use heartbeat protocol option.

Member Function Documentation

void trikNetwork::Connection::connected ( trikNetwork::Connection *  self )

signal

Emitted after connection is established.

void trikNetwork::Connection::disconnected ( trikNetwork::Connection *  self )

signal

Emitted after connection becomes closed.

void Connection::init

(

qintptr

socketDescriptor

)

Creates socket and initializes incoming connection, shall be called when Connection is already in its own thread.

Parameters

socketDescriptor

- native socket descriptor.

void Connection::init ( const QHostAddress &  ip, int  port  )

protected

Creates socket and initializes outgoing connection, shall be called when Connection is already in its own thread.

Parameters

ip	- target ip address.
port	- target port.

bool Connection::isConnected

(

)

const

Returns true if socket is opened or false otherwise.

bool Connection::isValid

(

)

const

Checks if socket is valid or not Attention!!! Hot fix for NTI contest.

There are a lot of incorrect interaction between threads, this dirty fix checks that current connection exists. For example, sometimes thread and connection are added/deleted to mConnections in TrikServer, but actually they are not added/deleted.

QHostAddress Connection::peerAddress

(

)

const

Returns peer address of a connection, if it is open, or empty QHostAddress if connection is not established yet.

int Connection::peerPort

(

)

const

Returns peer port of a connection, if it is open, or -1 if connection is not established yet.

void Connection::send

(

const QByteArray &

data

)

Sends given byte array to peer.

Reset keepalive timer to avoid spamming with keepalive packets.
