Detailed Description

The singleton type used to configure RTI Connext logging.

Member Function Documentation

◆ instance()

static Logger& rti::config::Logger::instance ( )

static

Get the singleton instance of this type.

Examples:: Foo_publisher.cxx, and Foo_subscriber.cxx.

Referenced by rti::config::ScopedLoggerVerbosity::ScopedLoggerVerbosity(), and rti::config::ScopedLoggerVerbosity::~ScopedLoggerVerbosity().

◆ verbosity() [1/2]

Verbosity rti::config::Logger::verbosity ( )

Get the verbosity at which RTI Connext is currently logging diagnostic information.

The default verbosity if Logger::verbosity is never called is rti::core::LogVerbosity::EXCEPTION.

If Logger::verbosity_by_category has been used to set different verbosities for different categories of messages, this method will return the maximum verbosity of all categories.

Examples:: Foo_publisher.cxx, and Foo_subscriber.cxx.

Referenced by rti::config::ScopedLoggerVerbosity::ScopedLoggerVerbosity(), and rti::config::ScopedLoggerVerbosity::~ScopedLoggerVerbosity().

◆ verbosity_by_category() [1/2]

Verbosity rti::config::Logger::verbosity_by_category ( LogCategory category )

Get the verbosity at which RTI Connext is currently logging diagnostic information in the given category.

The default verbosity if Logger::verbosity and Logger::verbosity_by_category are never called is rti::core::LogVerbosity::EXCEPTION.

◆ verbosity() [2/2]

void rti::config::Logger::verbosity ( Verbosity verbosity )

Set the verbosity at which RTI Connext will log diagnostic information.

Note: Logging at high verbosities will be detrimental to your application's performance. Your default setting should typically remain at rti::core::LogVerbosity::WARNING or below. (The default verbosity if you never set it is rti::core::LogVerbosity::EXCEPTION.)

◆ verbosity_by_category() [2/2]

void rti::config::Logger::verbosity_by_category	(	LogCategory	category,
		Verbosity	verbosity
	)

Set the verbosity at which RTI Connext will log diagnostic information in the given category.

◆ output_file() [1/3]

FILE* rti::config::Logger::output_file ( )

Get the file to which the logged output is redirected.

If no output file has been registered through Logger::set_output_file, this method will return NULL. In this case, logged output will on most platforms go to standard out as if through printf.

◆ output_file() [2/3]

void rti::config::Logger::output_file ( FILE * out )

Set the file to which the logged output is redirected.

The file passed may be NULL, in which case further logged output will be redirected to the platform-specific default output location (standard out on most platforms).

For better performance when log messages are generated frequently, the log messages are not flushed into a file immediately after they are generated. In other words, while writing a log message, RTI Connext only calls the function fwrite() (see https://pubs.opengroup.org/onlinepubs/009695399/functions/fwrite.html); it does not call the function fflush() (see https://pubs.opengroup.org/onlinepubs/009695399/functions/fflush.html). If your application requires a different flushing behavior, you may use Logger::set_output_device to configure a custom logging device.

◆ output_file() [3/3]

void rti::config::Logger::output_file ( const char * file_name )

Set the name of the file to which the logged output is redirected.

The name may be NULL, in which case further logged output will be redirected to the platform-specific default output location (standard out on most platforms).

See Logger::set_output_file for the flushing behavior.

◆ output_file_set()

void rti::config::Logger::output_file_set	(	const char *	file_preffix,
		const char *	file_suffix,
		int	max_bytes,
		int	max_files = `dds::core::LENGTH_UNLIMITED`
	)

Set the name of the file to which the logged output is redirected.

The name may be NULL, in which case further logged output will be redirected to the platform-specific default output location (standard out on most platforms).

See Logger::set_output_file for the flushing behavior.

◆ print_format() [1/2]

PrintFormat rti::config::Logger::print_format ( )

Get the current message format for the log level LogLevel::EXCEPTION.

Use Logger::get_print_format_by_log_level to retrieve the format for other log levels.

If Logger::set_print_format is never called, the default format is PrintFormat::DEFAULT.

◆ print_format() [2/2]

void rti::config::Logger::print_format ( PrintFormat print_format )

Set the message format that RTI Connext will use to log diagnostic information for all the log levels, except for LogLevel::FATAL_ERROR. When the Activity Context is printed, the user can select the information that will be part of the Activity Context by using the API rti::config::activity_context::set_attribute_mask.

◆ print_format_by_log_level() [1/2]

PrintFormat rti::config::Logger::print_format_by_log_level ( LogLevel log_level )

Get the current message format, by log level, that RTI Connext is using to log diagnostic information.
