static LINPHONECXX_PUBLIC std::shared_ptr< linphone::LoggingService > | get ()

## Detailed Description

Singleton class giving access to logging features.

It supports custom domain, writing into a file as well as several verbosity levels. The LinphoneLoggingServiceCbs listener allows you to be notified each time a log is printed. As the LoggingService is a singleton, use get() to get it.

## Member Function Documentation

## ◆ debug()

LINPHONECXX_PUBLIC void linphone::LoggingService::debug | ( | const std::string & | message | ) |

Write a LinphoneLogLevelDebug message to the logs.

Parameters

  message | The log message.

## ◆ enableStackTraceDumps()

LINPHONECXX_PUBLIC void linphone::LoggingService::enableStackTraceDumps | ( | bool | enable | ) |

Allow Linphone to set handlers for catching exceptions and write the stack trace into log.

Available for Windows. It keeps old handlers.

Parameters

  enable | if true global handlers will be prepend by the logger handlers. By default, it is false.

## ◆ error()

LINPHONECXX_PUBLIC void linphone::LoggingService::error | ( | const std::string & | message | ) |

Write a LinphoneLogLevelError message to the logs.

Parameters

  message | The log message.

## ◆ fatal()

LINPHONECXX_PUBLIC void linphone::LoggingService::fatal | ( | const std::string & | message | ) |

Write a LinphoneLogLevelFatal message to the logs.

Parameters

  message | The log message.

## ◆ get()

static LINPHONECXX_PUBLIC std::shared_ptr< linphone::LoggingService > linphone::LoggingService::get | ( |  | ) |
| static

Gets the singleton logging service object.

The singleton is automatically instantiated if it hasn't been done yet.

Returns
  A pointer on the LoggingService singleton.

## ◆ getDomain()

LINPHONECXX_PUBLIC std::string linphone::LoggingService::getDomain | ( |  | ) |

Get the domain where application logs are written (for example with message()).

Returns
  The domain where application logs are written.

## ◆ getLogLevelMask()

LINPHONECXX_PUBLIC unsigned int linphone::LoggingService::getLogLevelMask | ( |  | ) | const

Gets the log level mask.

Returns
  the log level mask

## ◆ message()

LINPHONECXX_PUBLIC void linphone::LoggingService::message | ( | const std::string & | message | ) |

Write a LinphoneLogLevelMessage message to the logs.

Parameters

  message | The log message.

## ◆ setDomain()

LINPHONECXX_PUBLIC void linphone::LoggingService::setDomain | ( | const std::string & | domain | ) |

Set the domain where application logs are written (for example with message()).

Parameters

  domain | The domain.

Note
  The domain is mandatory to write logs. This needs to be set before setting the log level.

## ◆ setLogFile()

LINPHONECXX_PUBLIC void linphone::LoggingService::setLogFile | ( | const std::string & | dir,
|  | const std::string & | filename,
|  | size_t | maxSize
| ) |  | const

Enables logging in a file.

That function enables an internal log handler that writes log messages in log-rotated files.

Parameters

  maxSize | The maximal size of each part of the log. The log rotating is triggered each time the currently opened log part reach that limit.

## ◆ setLogLevel()

LINPHONECXX_PUBLIC void linphone::LoggingService::setLogLevel | ( | linphone::LogLevel | level | ) |

Set the verbosity of the log.

For instance, a level of LogLevel::Message will let pass fatal, error, warning and message-typed messages whereas trace and debug messages will be dumped out.

Parameters

  level | the LogLevel to set

## ◆ setLogLevelMask()

LINPHONECXX_PUBLIC void linphone::LoggingService::setLogLevelMask | ( | unsigned int | mask | ) |

Sets the types of messages that will be authorized to be written in the log.

Parameters

  mask | Example: LogLevel::Message|LogLevel::Error will ONLY let pass message-typed and error messages.

Note
  Calling that function reset the log level that has been specified by setLogLevel().

## ◆ trace()

LINPHONECXX_PUBLIC void linphone::LoggingService::trace | ( | const std::string & | message | ) |

Write a LinphoneLogLevelTrace message to the logs.

Parameters

  message | The log message.

## ◆ warning()

LINPHONECXX_PUBLIC void linphone::LoggingService::warning | ( | const std::string & | message | ) |

Write a LinphoneLogLevelWarning message to the logs.

Parameters

  message | The log message.
