class TApplicationServer: public TApplication


TApplicationServer

TApplicationServer is the remote application run by the roots main
 program. The input is taken from the socket connection to the client.

Function documentation

TApplicationServer(Int_t* argc, char** argv, FILE* flog, const char* logfile)
 Main constructor. Create an application environment. The TApplicationServer
 environment provides an eventloop via inheritance of TApplication.
Int_t Setup()
 Print the Remote Server logo on standard output.
 Return 0 on success, -1 on failure
~TApplicationServer()
 Cleanup. Not really necessary since after this dtor there is no
 live anyway.
void GetOptions(Int_t* argc, char** argv)
 Get and handle command line options. Fixed format:
 "protocol  url"
void Run(Bool_t retrn = kFALSE)
 Main server eventloop.
void HandleSocketInput()
 Handle input coming from the client or from the master server.
void HandleUrgentData()
 Handle Out-Of-Band data sent by the master or client.
void HandleSigPipe()
 Called when the client is not alive anymore (i.e. when kKeepAlive
 has failed).
void Reset(const char* dir)
 Reset environment to be ready for execution of next command.
Int_t ReceiveFile(const char* file, Bool_t bin, Long64_t size)
 Receive a file, either sent by a client or a master server.
 If bin is true it is a binary file, other wise it is an ASCII
 file and we need to check for Windows \r tokens. Returns -1 in
 case of error, 0 otherwise.
void SendLogFile(Int_t status = 0, Int_t start = -1, Int_t end = -1)
 Send log file to master.
 If start > -1 send only bytes in the range from start to end,
 if end <= start send everything from start.
Int_t SendCanvases()
 Send any created canvas to client
Int_t BrowseDirectory(const char* dirname)
 Browse directory and send back its content to client.
Int_t BrowseFile(const char* fname)
 Browse root file and send back its content;
 if fname is null, send the full list of files.
Int_t BrowseKey(const char* keyname)
 Read key object and send it back to client.
void Terminate(Int_t status)
 Terminate the proof server.
void HandleCheckFile(TMessage* mess)
 Handle file checking request.
void ErrorHandler(Int_t level, Bool_t abort, const char* location, const char* msg)
 The error handler function. It prints the message on stderr and
 if abort is set it aborts the application.
Long_t ProcessLine(const char* line, Bool_t = kFALSE, Int_t* err = 0)
 Parse a command line received from the client, making sure that the files
 needed for the execution, if any, are available. The line is either a C++
 statement or an interpreter command starting with a ".".
 Return the return value of the command casted to a long.
void ExecLogon()
 Execute logon macro's. There are three levels of logon macros that
 will be executed: the system logon etc/system.rootlogon.C, the global
 user logon ~/.rootlogon.C and the local ./.rootlogon.C. For backward
 compatibility also the logon macro as specified by the Rint.Logon
 environment setting, by default ./rootlogon.C, will be executed.
 No logon macros will be executed when the system is started with
 the -n option.
Int_t GetProtocol()
{ return fProtocol; }
Int_t GetPort()
{ return fUrl.GetPort(); }
const char * GetUser()
{ return fUrl.GetUser(); }
const char * GetHost()
{ return fUrl.GetHost(); }
TSocket * GetSocket()
{ return fSocket; }
void Interrupt()
{ fInterrupt = kTRUE; }
Bool_t IsValid()
{ return fIsValid; }
