Detailed Description

<<interface>> The singleton type used to configure RTI Connext logging.

Member Function Documentation

◆ get_instance()

static NDDSConfigLogger* NDDSConfigLogger::get_instance ( )

static

Get the singleton instance of this type.

Examples:: HelloWorld_publisher.cxx, and HelloWorld_subscriber.cxx.

◆ finalize_instance()

static void NDDSConfigLogger::finalize_instance ( )

static

Finalize the singleton instance of this type.

MT Safety:: UNSAFE. It is not safe to call this method while another thread may be simultaneously calling another logger-related method, including this one.

◆ get_verbosity()

NDDS_Config_LogVerbosity NDDSConfigLogger::get_verbosity ( )

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

The default verbosity if NDDSConfigLogger::set_verbosity is never called is NDDS_CONFIG_LOG_VERBOSITY_ERROR.

If NDDSConfigLogger::set_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.

◆ get_verbosity_by_category()

NDDS_Config_LogVerbosity NDDSConfigLogger::get_verbosity_by_category ( NDDS_Config_LogCategory category )

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

The default verbosity if NDDSConfigLogger::set_verbosity and NDDSConfigLogger::set_verbosity_by_category are never called is NDDS_CONFIG_LOG_VERBOSITY_ERROR.

◆ set_verbosity()

void NDDSConfigLogger::set_verbosity ( NDDS_Config_LogVerbosity 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 NDDS_CONFIG_LOG_VERBOSITY_WARNING or below. (The default verbosity if you never set it is NDDS_CONFIG_LOG_VERBOSITY_ERROR.)

Examples:: HelloWorld_publisher.cxx, and HelloWorld_subscriber.cxx.

◆ set_verbosity_by_category()

void NDDSConfigLogger::set_verbosity_by_category	(	NDDS_Config_LogCategory	category,
		NDDS_Config_LogVerbosity	verbosity
	)

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

◆ get_output_file()

FILE* NDDSConfigLogger::get_output_file ( )

Get the file to which the logged output is redirected.

If no output file has been registered through NDDSConfigLogger::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.

◆ set_output_file()

bool NDDSConfigLogger::set_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 NDDSConfigLogger::set_output_device to configure a custom logging device.

◆ set_output_file_set()

bool NDDSConfigLogger::set_output_file_set	(	const char *	file_prefix,
		const char *	file_suffix,
		int	max_capacity,
		int	max_files
	)

Configure a set of files to redirect the logged output.

The logged output will be redirected to a set of files whose names are configured with a prefix and a suffix. The maximum number of bytes configures how many bytes to write into a file before opening the next file. After reaching the maximum number of files, the first one is overwritten.

For example, if the prefix is 'Foo', the suffix is '.txt', the max number of bytes is 1GB, and the max number of files is 3, the logger will create (at most) these files: Foo1.txt, Foo2.txt, and Foo3.txt. It will write to Foo1.txt, and after writing 1GB, it will move on to Foo2.txt, then to Foo3.txt, then to Foo1.txt again, and so on.

To stop logging to these files and redirect the output to the platform-specific location, pass NULL, NULL, 0, 0.

See NDDSConfigLogger::set_output_file for the flushing behavior.

◆ get_output_device()

NDDSConfigLoggerDevice* NDDSConfigLogger::get_output_device ( )

Return the user device registered with the logger.

Returns: Registered user device or NULL if no user device is registered.

◆ set_output_device()

bool NDDSConfigLogger::set_output_device ( NDDSConfigLoggerDevice * device )

Register a NDDSConfigLoggerDevice.

Register the specified logging device with the logger.

There can be at most only one device registered with the logger at any given time.

When a device is installed, the logger will stop sending the log messages to the standard output and to the file set with NDDSConfigLogger::set_output_file.

To remove an existing device, use this method with NULL as the device parameter. After a device is removed the logger will continue sending log messages to the standard output and to the output file.

To replace an existing device with a new device, use this method providing the new device as the device parameter.

When a device is unregistered (by setting it to NULL), NDDSConfigLoggerDevice calls the method NDDSConfigLoggerDevice::close.

Parameters

device <<in>> Logging device.

◆ get_print_format()

NDDS_Config_LogPrintFormat NDDSConfigLogger::get_print_format ( )

Get the current message format for the log level NDDS_CONFIG_LOG_LEVEL_ERROR.

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

If NDDSConfigLogger::set_print_format is never called, the default format is NDDS_CONFIG_LOG_PRINT_FORMAT_DEFAULT.

◆ set_print_format()

bool NDDSConfigLogger::set_print_format ( NDDS_Config_LogPrintFormat print_format )

Set the message format that RTI Connext will use to log diagnostic information for all the log levels, except for NDDS_CONFIG_LOG_LEVEL_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 NDDSConfigActivityContext::set_attribute_mask.

◆ get_print_format_by_log_level()

NDDS_Config_LogPrintFormat NDDSConfigLogger::get_print_format_by_log_level ( NDDS_Config_LogLevel log_level )

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