Detailed Description

Interface to be implemented to consume log from the library.

Instances of implemented classes are obtained by the library through the LoggerProvider instance set on LightstreamerClient#setLoggerProvider.

Member Function Documentation

debug()

virtual void Lightstreamer::Logger::debug ( const std::string & line )

pure virtual

Receives log messages at Debug level.

Parameters

line	The message to be logged.

error()

virtual void Lightstreamer::Logger::error ( const std::string & line )

pure virtual

Receives log messages at Error level.

Parameters

line	The message to be logged.

fatal()

virtual void Lightstreamer::Logger::fatal ( const std::string & line )

pure virtual

Receives log messages at Fatal level.

Parameters

line	The message to be logged.

info()

virtual void Lightstreamer::Logger::info ( const std::string & line )

pure virtual

Receives log messages at Info level.

Parameters

line	The message to be logged.

isDebugEnabled()

virtual bool Lightstreamer::Logger::isDebugEnabled ( )

pure virtual

Checks if this logger is enabled for the Debug level.

The property should be true if this logger is enabled for Debug events, false otherwise.
This property is intended to lessen the computational cost of disabled log Debug statements. Note that even if the property is false, Debug log lines may be received anyway by the Debug methods.

Returns

true if the Debug logger is enabled

isErrorEnabled()

virtual bool Lightstreamer::Logger::isErrorEnabled ( )

pure virtual

Checks if this logger is enabled for the Error level.

The property should be true if this logger is enabled for Error events, false otherwise.
This property is intended to lessen the computational cost of disabled log Error statements. Note that even if the property is false, Error log lines may be received anyway by the Error methods.

Returns

true if the Error logger is enabled

isFatalEnabled()

virtual bool Lightstreamer::Logger::isFatalEnabled ( )

pure virtual

Checks if this logger is enabled for the Fatal level.

The property should be true if this logger is enabled for Fatal events, false otherwise.
This property is intended to lessen the computational cost of disabled log Fatal statements. Note that even if the property is false, Fatal log lines may be received anyway by the Fatal methods.

Returns

true if the Fatal logger is enabled

isInfoEnabled()

virtual bool Lightstreamer::Logger::isInfoEnabled ( )

pure virtual

Checks if this logger is enabled for the Info level.

The property should be true if this logger is enabled for Info events, false otherwise.
This property is intended to lessen the computational cost of disabled log Info statements. Note that even if the property is false, Info log lines may be received anyway by the Info methods.

Returns

true if the Info logger is enabled

isTraceEnabled()

virtual bool Lightstreamer::Logger::isTraceEnabled ( )

pure virtual

Checks if this logger is enabled for the Trace level.

The property should be true if this logger is enabled for Trace events, false otherwise.
This property is intended to lessen the computational cost of disabled log Trace statements. Note that even if the property is false, Trace log lines may be received anyway by the Trace methods.

Returns

true if the Trace logger is enabled

isWarnEnabled()

virtual bool Lightstreamer::Logger::isWarnEnabled ( )

pure virtual

Checks if this logger is enabled for the Warn level.

The property should be true if this logger is enabled for Warn events, false otherwise.
This property is intended to lessen the computational cost of disabled log Warn statements. Note that even if the property is false, Warn log lines may be received anyway by the Warn methods.

Returns

true if the Warn logger is enabled

trace()

virtual void Lightstreamer::Logger::trace ( const std::string & line )

pure virtual

Receives log messages at Trace level.

Parameters

line	The message to be logged.

warn()

virtual void Lightstreamer::Logger::warn ( const std::string & line )

pure virtual

Receives log messages at Warn level.

Parameters

line	The message to be logged.
