Detailed Description

The TLogger class provides an abstract base of logging functionality.

Constructor & Destructor Documentation

TLogger()

TLogger::TLogger

(

)

Constructor.

~TLogger()

virtual TLogger::~TLogger ( )

inlinevirtual

Member Function Documentation

close()

void TLogger::close ( )

pure virtual

Closes the device.

This function should be called from any reimplementations of close().

Implemented in TStdOutLogger.

dateTimeFormat()

const QByteArray & TLogger::dateTimeFormat

(

)

const

Returns a reference to the value for the setting datetime format.

encoding()

QStringConverter::Encoding TLogger::encoding ( ) const

protected

Returns a pointer to QTextCodec of the default text encoding.

flush()

void TLogger::flush ( )

inlinevirtual

Flushes any buffered data to the device.

This function should be called from any reimplementations of flush().

Reimplemented in TStdOutLogger.

isMultiProcessSafe()

bool TLogger::isMultiProcessSafe ( ) const

pure virtual

Returns true if the implementation is guaranteed to be free of race conditions when accessed by multiple processes simultaneously; otherwise returns false.

Implemented in TStdOutLogger.

isOpen()

bool TLogger::isOpen ( ) const

pure virtual

Returns true if the device is open; otherwise returns false.

This function should be called from any reimplementations of isOpen().

Implemented in TStdOutLogger.

key()

QString TLogger::key ( ) const

pure virtual

Returns a key that this logger plugin supports.

Implemented in TStdOutLogger.

layout()

const QByteArray & TLogger::layout

(

)

const

Returns a reference to the value for the setting layout.

log() [1/2]

virtual void TLogger::log ( const QByteArray &  )

pure virtual

Implemented in TStdOutLogger.

log() [2/2]

void TLogger::log ( const TLog &  log )

inlinevirtual

Writes the log log to the device.

This function should be called from any reimplementations of log().

logToByteArray() [1/2]

QByteArray TLogger::logToByteArray ( const TLog &  log ) const

virtual

Converts the log log to its textual representation and returns a QByteArray containing the data.

logToByteArray() [2/2]

QByteArray TLogger::logToByteArray ( const TLog &  log, const QByteArray &  layout, const QByteArray &  dateTimeFormat, QStringConverter::Encoding  encoding = QStringConverter::Utf8  )

static

Converts the log log to its textual representation and returns a QByteArray containing the data.

open()

bool TLogger::open ( )

pure virtual

Opens the device for logging.

Returns true if successful; otherwise returns false. This function should be called from any reimplementations of open().

Implemented in TStdOutLogger.

priorityToString()

QByteArray TLogger::priorityToString ( Tf::LogPriority  priority )

static

Returns a QByteArray containing the priority priority.

settingsValue()

QVariant TLogger::settingsValue ( const QString &  k, const QVariant &  defaultValue = QVariant()  ) const

protected

Returns the value for logger setting key.

If the setting doesn't exist, returns defaultValue.

target()

const QString & TLogger::target

(

)

const

Returns a reference to the value for the setting target device.

threshold()

Tf::LogPriority TLogger::threshold

(

)

const

Returns the value for the setting priority threshold.
