Member Function Documentation

◆ appName()

std::string BESApp::appName ( void  ) const
inlineinherited

Returns the name of the application.

The name of the application is typically argv[0] passed into the main function. But could be passed into the application or derived in a different way.

Returns
name of the application

Definition at line 128 of file BESApp.h.

◆ dump()

void ServerApp::dump ( std::ostream &  strm) const
virtual

dumps information about this object

Displays the pointer value of this instance

Parameters
strmC++ i/o stream to dump the information to

Reimplemented from BESModuleApp.

Definition at line 634 of file ServerApp.cc.

◆ initialize()

int ServerApp::initialize ( int  argC,
char **  argV 
)
virtual

Load and initialize any BES modules.

Returns
0 if successful and not 0 otherwise
Parameters
argCargc value passed to the main function
argVargv value passed to the main function

Reimplemented from BESModuleApp.

Definition at line 277 of file ServerApp.cc.

◆ main()

int BESApp::main ( int  argC,
char **  argV 
)
virtualinherited

main routine, the main entry point for any BES applications.

main method of the BES application

It is up to the derived classes of BESApp to implement the main routine. However, the main method should call initialize, run and terminate in that order and should pass to the initialize routine the arguments argc and argv passed to the main function.

Parameters
argCnumber of arguments passed to the application, which is argc passed to the main function.
argVarguments passed to the application, which is argv passed to the main function.

sets the appName to argv[0], then calls initialize, run, and terminate in that order. Exceptions should be caught in the individual methods initialize, run and terminate and handled there.

Returns
0 if successful and not 0 otherwise
Parameters
argCargc value passed to the main function
argVargv value passed to the main function

Definition at line 54 of file BESApp.cc.

◆ run()

int ServerApp::run ( )
virtual

The body of the application, implementing the primary functionality of the BES application.

the applications functionality is implemented in the run method

It is up to the derived classes of BESApp to implement the run method.

It is up to the derived class to implement this method.

Returns
0 if successful and not 0 otherwise
Exceptions
BESErrorif the derived class does not implement this method

Reimplemented from BESApp.

Definition at line 471 of file ServerApp.cc.

◆ terminate()

int ServerApp::terminate ( int  sig = 0)
virtual

clean up after the application

Calls terminate on each of the loaded modules

Returns
0 if successful and not 0 otherwise
Parameters
sigif the application is terminating due to a signal, otherwise 0 is passed.

Reimplemented from BESModuleApp.

Definition at line 588 of file ServerApp.cc.

◆ TheApplication()

static BESApp* BESApp::TheApplication ( void  )
inlinestaticinherited

Returns the BESApp application object for this application.

Returns
The application object
