Detailed Description

Manages POSIX signals for the application.

Singleton that captures specific POSIX signals (e.g., SIGUSR1 and SIGUSR2) during the runtime of the application. It provides mechanisms to check if signals have been raised and ensures proper cleanup and handling.

Constructor & Destructor Documentation

SignalHandler()

Core::SignalHandler::SignalHandler ( )

explicit

Constructor for SignalHandler.

Sets up the signal handlers for SIGUSR1 and SIGUSR2. Throws a runtime error if more than one instance of SignalHandler is created.

Here is the call graph for this function:

Member Function Documentation

handle_SIGINT()

void Core::SignalHandler::handle_SIGINT ( int signal )

staticprivatenoexcept

Here is the caller graph for this function:

handle_SIGUSR1()

void Core::SignalHandler::handle_SIGUSR1 ( int signal )

staticprivatenoexcept

Handles the SIGUSR1 signal.

This static function is called when the SIGUSR1 signal is raised. It sets the internal flag to indicate the signal was received.

Parameters

signal

The signal number (ignored in this implementation).

Here is the caller graph for this function:

handle_SIGUSR2()

void Core::SignalHandler::handle_SIGUSR2 ( int signal )

staticprivatenoexcept

Handles the SIGUSR2 signal.

This static function is intended to handle the SIGUSR2 signal. (Implementation pending.)

Parameters

signal

The signal number (ignored in this implementation).

Here is the caller graph for this function:

is_sigint_raised()

static bool Core::SignalHandler::is_sigint_raised ( )

inlinestaticnodiscard

is_usr1_raised()

static bool Core::SignalHandler::is_usr1_raised ( )

inlinestaticnodiscard

Checks if the SIGUSR1 signal has been raised.

This function is used to query the state of the SIGUSR1 signal. If the signal has been raised, the function returns true and resets the internal flag to false.

Exceptions

std::runtime_error

If the SignalHandler instance has not been initialized.

Returns

true if SIGUSR1 was raised since the last query; false otherwise.

is_usr2_raised()

static bool Core::SignalHandler::is_usr2_raised ( )
