Detailed Description

Manages registration and unregistration of loggers.

This class handles a single responsibility: tracking registered loggers. It provides thread-safe registration/unregistration and query operations.

Thread Safety: All methods are thread-safe. Uses shared_mutex for reader-writer lock optimization (multiple readers, single writer).

Constructor & Destructor Documentation

logger_registry()

kcenon::logger::core::logger_registry::logger_registry ( )

default

Default constructor.

Member Function Documentation

empty()

bool kcenon::logger::core::logger_registry::empty

(

)

const

Check if registry is empty.

Returns

true if no loggers are registered

Definition at line 49 of file logger_registry.cpp.

{
    std::shared_lock lock(mutex_);
    return loggers_.empty();
}

References loggers_, and mutex_.

get_registered_loggers()

auto kcenon::logger::core::logger_registry::get_registered_loggers

(

)

const -> std::vector<security::critical_logger_interface*>

Get all registered loggers.

Returns

Vector of registered logger pointers

Returns a snapshot of currently registered loggers. The returned vector is a copy and safe to iterate without holding locks.

Definition at line 42 of file logger_registry.cpp.

{
    std::shared_lock lock(mutex_);
    return loggers_;
}

References loggers_, and mutex_.

register_logger()

void kcenon::logger::core::logger_registry::register_logger

(

security::critical_logger_interface *

log

)

Register a logger for tracking.

Parameters

log	Logger implementing critical_logger_interface

Adds the logger to the internal registry. If the logger is already registered, this is a no-op.

Definition at line 12 of file logger_registry.cpp.

{
    if (!log) {
        return;
    }
 
    std::unique_lock lock(mutex_);
 
    // Check if already registered
    auto it = std::find(loggers_.begin(), loggers_.end(), log);
    if (it == loggers_.end()) {
        loggers_.push_back(log);
    }
}

References loggers_, and mutex_.

size()

size_t kcenon::logger::core::logger_registry::size

(

)

const

Get number of registered loggers.

Returns

Count of registered loggers

Definition at line 55 of file logger_registry.cpp.

{
    std::shared_lock lock(mutex_);
    return loggers_.size();
}

References loggers_, and mutex_.

unregister_logger()

void kcenon::logger::core::logger_registry::unregister_logger

(

security::critical_logger_interface *

log

)

Unregister a logger.

Parameters

log	Logger to unregister

Removes the logger from the internal registry. If the logger is not registered, this is a no-op.

Definition at line 27 of file logger_registry.cpp.

{
    if (!log) {
        return;
    }
 
    std::unique_lock lock(mutex_);
 
    // Remove all instances (should be only one, but use remove to be safe)
    loggers_.erase(
        std::remove(loggers_.begin(), loggers_.end(), log),
        loggers_.end()
    );
}
