Detailed Description

A TcpClient object is used to communicate with a TcpServer. Any number of clients can connect to a TcpServer, each connected client spawns a TcpClientConnection object on the server side which represents this client on the server. Sending and receiving data is handled through streams, streams offer the most flexible model to read and write data in different formats by connecting different stream readers and stream writers. The idea is to write data to the send stream, and to send of the accumulated data in the send stream once by calling the Send() method. To receive data from the server, call the Recv() method which will either block until, or return true in non-blocking mode as soon as data is available. The received data will be written into the receive stream, where the application can read it in any way it desires.

Member Function Documentation

StdTcpClient::Result Net::StdTcpClient::Connect (  ) 

establish a connection with the server

Establish a connection with the server. If the client is set to non-blocking at the time this method is called, it will return immediately with the result Connecting. To check if the connection is standing, just call Connect() again in intervals which will eventually return Success. On a blocking client, connect returns after a connection has been established, or with a time out when no connection could be established.

Reimplemented in Net::MessageClient.

void Net::StdTcpClient::Disconnect (  ) 

disconnect from the server

This disconnects the current connection.

Reimplemented in Net::MessageClient.

bool Net::StdTcpClient::IsConnected (  ) 

return true if currently connected

Return true if the socket is currently connected. This will actually probe the connection using a select().

int Core::RefCounted::GetRefCount (  )  const [inline, inherited]

get the current refcount

Return the current refcount of the object.

void Core::RefCounted::AddRef (  )  [inline, inherited]

increment refcount by one

Increment the refcount of the object.

void Core::RefCounted::Release (  )  [inline, inherited]

decrement refcount and destroy object if refcount is zero

Decrement the refcount and destroy object if refcount is zero.

const Util::String & Core::RefCounted::GetClassName (  )  const [inline, inherited]

get the class name

Get the class name of the object.

Util::FourCC Core::RefCounted::GetClassFourCC (  )  const [inline, inherited]

get the class FourCC code

Get the class FourCC of the object.

void Core::RefCounted::DumpRefCountingLeaks (  )  [static, inherited]

dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)

This method should be called as the very last before an application exits.
