Detailed Description

Sample server that echoes messages to the terminal and back to the sender.

This server blocks on new connections, so is not generally an appropriate component for a real system. It is, however, illustrative of putting things together.

Member Function Documentation

const SocketBuilder& CODEX_Quorum::LocalServer::builder (   )  const [inline, protected, inherited]

Returns the SocketBuilder for this server. Definition at line 120 of file LocalServer.h. Referenced by CODEX_KeyService::ClientServer::processRequest().

void LocalServer::disable (   )  [virtual, inherited]

Stop listening and destroy the open socket. Derived classes needing to clean up any state on shutdown should reimplement this method. This base-class version should be called explicitly, to ensure the necessary base class cleanup. Reimplemented in CODEX_Server::InternalVerifier. Definition at line 53 of file LocalServer.cc. Referenced by CODEX_Server::InternalVerifier::disable().

void LocalServer::enable (   )  [virtual, inherited]

Create a socket and begin listening. Derived classes should reimplement this to perform other service initialization tasks needed. This base-class version should be called explicitly, to ensure the necessary base class initialization. Definition at line 41 of file LocalServer.cc. References CODEX_Quorum::SocketBase::setup().

bool LocalServer::isset_fd (  const fd_set *  fd_bitmap, SocketBase::StateType  s )  [virtual, inherited]

Whether the bitmap is set for this socket. Some types of sockets may need to know the operation being tested. Definition at line 76 of file LocalServer.cc. References CODEX_Quorum::SocketBase::isset_fd().

void EchoServer::processRequest (  SocketBase::StateType  s  )  [virtual]

Process incoming requests. Derived classes must implement this routine, which is called whenever a connection is made. Attention: No further connections may be handled, nor any other actions taken, until this function returns. Consequently, if you do not want your program to block on a request, you must implement some concurrency mechanism, such as an event model or threads. This class makes no assumptions about concurrency. Implements CODEX_Quorum::LocalServer. Definition at line 31 of file EchoServer.cc. References CODEX_Quorum::SocketBase::accept(), CODEX_Quorum::SocketBase::isset_fd(), CODEX_Quorum::SocketBase::readFrom(), CODEX_Quorum::SocketBase::set_fd(), CODEX_Quorum::LocalServer::socket(), and CODEX_Quorum::SocketBase::writeTo().

int LocalServer::set_fd (  fd_set *  fd_bitmap, SocketBase::StateType  s )  [virtual, inherited]

Set the bitmap for this socket. Some types of sockets may need to know the operation being tested. Definition at line 69 of file LocalServer.cc. References CODEX_Quorum::SocketBase::set_fd().

void CODEX_Quorum::LocalServer::setSocket (  SocketBase *  socket  )  [inline, protected, inherited]

Set a SocketBase for this server. Useful for servers that clone themselves. Definition at line 126 of file LocalServer.h. References CODEX_Quorum::LocalServer::socket(). Referenced by CODEX_KeyService::ClientActivity::ClientActivity(), and CODEX_Server::InternalVerifier::InternalVerifier().
