Detailed Description

Abstract base class for logging subsystems.

Provides common interface and functionality for concrete loggers. Supports severity filtering and global enable/disable.

Note

Inherit from this class to create specific logger implementations

Example Usage:

class ConsoleLogger : public Logger {
protected:
    void write(LogLevel level, const std::string& message) override {
        std::cout << "[" << log_level_str(level) << "] " << message << "\n";
    }
};
 
ConsoleLogger logger;
logger.set_output_level(LogLevel::INFO);
logger.info("Application started");
logger.debug("This won't be shown"); // Filtered by output level

Definition at line 45 of file Logger.h.

output_level()

txeo::LogLevel txeo::Logger::output_level ( ) const

inline

Get current output level threshold.

Returns

Active LogLevel filter

Definition at line 76 of file Logger.h.

{ return _output_level; }

Here is the caller graph for this function:

set_output_level()

void txeo::Logger::set_output_level ( txeo::LogLevel  output_level )

inline

Set minimum logging level to output.

Parameters

output_level

Messages below this level will be filtered

Example Usage:

Definition at line 87 of file Logger.h.

{ _output_level = output_level; }

Here is the call graph for this function:

turn_off()

void txeo::Logger::turn_off ( )

inline

Disable all logging output.

Definition at line 70 of file Logger.h.

{ _is_turned_on = false; };

turn_on()

void txeo::Logger::turn_on ( )

inline

Enable logging operations.

Definition at line 65 of file Logger.h.

{ _is_turned_on = true; };

warning()

protectedpure virtual

Abstract write operation.

Parameters

level	Message severity level
message	Formatted log content
