Constructor & Destructor Documentation

◆ TRint() [1/2]

TRint::TRint ( const TRint )
private

◆ TRint() [2/2]

TRint::TRint ( const char *  appClassName,
int *  argc,
char **  argv,
void options = 0,
int  numOptions = 0,
Bool_t  noLogo = kFALSE 
)

Create an application environment.

The TRint environment provides an interface to the WM manager functionality and eventloop via inheritance of TApplication and in addition provides interactive access to the Cling C++ interpreter via the command line.

Definition at line 143 of file TRint.cxx.

◆ ~TRint()

TRint::~TRint ( )
virtual

Destructor.

Definition at line 277 of file TRint.cxx.

Member Function Documentation

◆ ExecLogon()

void TRint::ExecLogon ( )
private

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.

Definition at line 302 of file TRint.cxx.

◆ GetInputHandler()

TFileHandler* TRint::GetInputHandler ( )
inline

Definition at line 64 of file TRint.h.

◆ GetPrompt()

char * TRint::GetPrompt ( )
virtual

Get prompt from interpreter. Either "root [n]" or "end with '}'".

Definition at line 534 of file TRint.cxx.

◆ HandleException()

void TRint::HandleException ( Int_t  sig)
virtual

Handle signals (kSigBus, kSigSegmentationViolation, kSigIllegalInstruction and kSigFloatingException) trapped in TSystem.

Specific TApplication implementations may want something different here.

Reimplemented from TApplication.

Definition at line 657 of file TRint.cxx.

◆ HandleTermInput()

Bool_t TRint::HandleTermInput ( )
virtual

Handle input coming from terminal.

Reimplemented from TApplication.

Definition at line 570 of file TRint.cxx.

◆ Interrupt()

void TRint::Interrupt ( )
inline

◆ operator=()

TRint& TRint::operator= ( const TRint )
private

◆ PrintLogo()

void TRint::PrintLogo ( Bool_t  lite = kFALSE)
virtual

Print the ROOT logo on standard output.

Definition at line 473 of file TRint.cxx.

◆ ProcessLineNr()

Long_t TRint::ProcessLineNr ( const char *  filestem,
const char *  line,
Int_t error = 0 
)
private

Calls ProcessLine() possibly prepending a line directive for better diagnostics.

Must be called after fNcmd has been increased for the next line.

Definition at line 741 of file TRint.cxx.

◆ ProcessRemote()

Long_t TRint::ProcessRemote ( const char *  line,
Int_t error = 0 
)
privatevirtual

Process the content of a line starting with ".R" (already stripped-off) The format is [user@]host[:dir] [-l user] [-d dbg] [script] The variable 'dir' is the remote directory to be used as working dir.

The username can be specified in two ways, "-l" having the priority (as in ssh). A 'dbg' value > 0 gives increasing verbosity. The last argument 'script' allows to specify an alternative script to be executed remotely to startup the session.

Reimplemented from TApplication.

Definition at line 719 of file TRint.cxx.

◆ Run()

void TRint::Run ( Bool_t  retrn = kFALSE)
virtual

Main application eventloop.

First process files given on the command line and then go into the main application event loop, unless the -q command line option was specified in which case the program terminates. When return is true this method returns even when -q was specified.

When QuitOpt is true and return is false, terminate the application with an error code equal to either the ProcessLine error (if any) or the return value of the command casted to a long.

Reimplemented from TApplication.

Definition at line 345 of file TRint.cxx.

◆ SetEchoMode()

void TRint::SetEchoMode ( Bool_t  mode)
virtual

Set console mode:

mode = kTRUE - echo input symbols mode = kFALSE - noecho input symbols

Reimplemented from TApplication.

Definition at line 703 of file TRint.cxx.

◆ SetPrompt()

const char * TRint::SetPrompt ( const char *  newPrompt)
virtual

Set a new default prompt.

It returns the previous prompt. The prompt may contain a d which will be replaced by the commend number. The default prompt is "root [%d] ". The maximum length of the prompt is 55 characters. To set the prompt in an interactive session do: root [0] ((TRint*)gROOT->GetApplication())->SetPrompt("aap> ") aap>

Definition at line 554 of file TRint.cxx.

◆ TabCompletionHook()

Int_t TRint::TabCompletionHook ( char *  buf,
int *  pLoc,
std::ostream &  out 
)
virtual

Forward tab completion request to our TTabCom::Hook().

Reimplemented from TApplication.

Definition at line 770 of file TRint.cxx.

◆ Terminate()

void TRint::Terminate ( int  status)
virtual

Terminate the application.

Reset the terminal to sane mode and call the logoff macro defined via Rint.Logoff environment variable.

Reimplemented from TApplication.
