Detailed Description

Base application object for all BES applications.

Implements the initialization method to initialize all global objects registered with the Global Initialization routines of BES.

Implements the terminate method to clean up any global objects registered with the Global Initialization routines of BES.

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

Constructor & Destructor Documentation

◆ BESModuleApp()

BESModuleApp::BESModuleApp ( )

Default constructor.

Initialized the static _the Applicatioon to point to this application object

Definition at line 50 of file BESModuleApp.cc.

Member Function Documentation

◆ appName()

std::string BESApp::appName ( ) 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 130 of file BESApp.h.

◆ dump()

void BESModuleApp::dump ( std::ostream & strm) const
overridevirtual

dumps information about this object

Displays the pointer value of this instance along with the name of the application, whether the application is initialized or not and whether the application debugging is turned on.

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

Implements BESApp.

Reimplemented in ServerApp, and StandAloneApp.

◆ initialize()

int BESModuleApp::initialize ( int argC,
char ** argV )
overridevirtual

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 BESApp.

Reimplemented in ServerApp, and StandAloneApp.

◆ 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 52 of file BESApp.cc.

◆ run()

int BESApp::run ( )
virtualinherited

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 in CmdApp, ServerApp, and StandAloneApp.

Definition at line 84 of file BESApp.cc.

◆ terminate()

int BESModuleApp::terminate ( int sig = 0)
overridevirtual

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.
