Type	Name
	GradientEngineApplication ()
	GradientEngineApplication (const GradientEngineApplication &) = delete
int	initialize (int argc, char ** argv) Parse CLI arguments, set up logging, prepare subsystems.
GradientEngineApplication &	operator= (const GradientEngineApplication &) = delete
int	run () Enter the main event loop, blocking until a signal is received.

Detailed Description

Owns the ConfigurationManager and optional CuemsLogger instance. Registers POSIX signal handlers for clean shutdown.

Public Functions Documentation

function GradientEngineApplication [1/2]

GradientEngineApplication::GradientEngineApplication () 

---

function GradientEngineApplication [2/2]

GradientEngineApplication::GradientEngineApplication (
    const GradientEngineApplication &
) = delete

---

function initialize

Parse CLI arguments, set up logging, prepare subsystems.

int GradientEngineApplication::initialize (
    int argc,
    char ** argv
) 

Parameters:

• argc Argument count from main().
• argv Argument vector from main().

Returns:

0 if initialization succeeded and run() should be called. Positive value on error (caller should exit with that code). Negative value if help or version was requested (exit 0).

Exception:

• None. Errors are logged and indicated via return value.

** **

GradientEngineApplication app;
int init = app.initialize(argc, argv);
if (init != 0) return (init < 0) ? 0 : init;
return app.run();

---

function operator=

GradientEngineApplication & GradientEngineApplication::operator= (
    const GradientEngineApplication &
) = delete

---

function run

Enter the main event loop, blocking until a signal is received.

int GradientEngineApplication::run () 

Returns:

Exit code (0 on clean shutdown).

Exception:

• None.

** **

return app.run();

---

function shutdown

Release resources and log shutdown event.

void GradientEngineApplication::shutdown () 

Called automatically by run() after the main loop exits, and also from the destructor as a safety net.

---

function ~GradientEngineApplication

GradientEngineApplication::~GradientEngineApplication ()
