Detailed Description

Generic interface to implement a logger.

Member Enumeration Documentation

LogLevel

enum libcdoc::ILogger::LogLevel

Log-level enumeration to indicate severity of the log message.

Enumerator
LEVEL_FATAL	Most critical level. Application is about to abort.
LEVEL_ERROR	Errors where functionality has failed or an exception have been caught.
LEVEL_WARNING	Warnings about validation issues or temporary failures that can be recovered.
LEVEL_INFO	Information that highlights progress or application lifetime events.
LEVEL_DEBUG	Debugging the application behavior from internal events of interest.
LEVEL_TRACE	Most verbose level. Used for development, NOP in production code.

Member Function Documentation

addLogger()

static int libcdoc::ILogger::addLogger ( ILogger *  logger )

static

Adds ILogger implementation to logging queue.

This function does not take ownership of the logger's instance. It is up to the caller to free the resources of the logger's instance and keep it alive until removed from the queue.

Parameters

logger

Logger's instance to be added.

Returns

Unique cookie identifying the logger's instance in the logging queue.

getLogger()

static ILogger * libcdoc::ILogger::getLogger ( )

static

Returns global logger's instance.

Returns

Global logger's instance.

Referenced by libcdoc::LogFormat(), and libcdoc::LogFormat().

GetMinLogLevel()

LogLevel libcdoc::ILogger::GetMinLogLevel ( ) const

inlinenoexcept

Returns current minimum log level of the logger.

Returns

Minimum log level.

LogMessage()

virtual void libcdoc::ILogger::LogMessage ( LogLevel  level, std::string_view  file, int  line, std::string_view  message  )

inlinevirtual

Logs given message with given severity, file name and line number.

Parameters

level	Severity of the log message.
file	File name where the log message was recorded.
line	Line number in the file where the log message was recorded.
message	The log message.

Every class implementing the ILogger interface must implement the member function. Default implementation does nothing.

Reimplemented in libcdoc::ConsoleLogger.

Referenced by libcdoc::LogFormat(), and libcdoc::LogFormat().

removeLogger()

static ILogger * libcdoc::ILogger::removeLogger ( int  cookie )

static

Removes logger's instance from the logging queue.

Parameters

cookie

Unique cookie returned by the add_logger function when the logger was added.

Returns

Pointer to ILogger object that is removed. It's up to user to free the resources.

SetMinLogLevel()

void libcdoc::ILogger::SetMinLogLevel ( LogLevel  level )

inlinenoexcept

Sets minimum log level for the logger.

Parameters

level

minimum level to log.

Sets minimum level of log messages to log. For example, if the minimum log level is set to LogLevelInfo (default), then LogLevelFatal, LogLevelError, LogLevelWarning and LogLevelInfo messages are logged, but not LogLevelDebug or LogLevelTrace messages.

Member Data Documentation

minLogLevel

LogLevel libcdoc::ILogger::minLogLevel

protected

Minimum level of log messages to log.
