Detailed Description

Thread-safe message logger.

This class aims to provide a thread-safe alternative to the JMessageLogger class. Indeed it can transparently replace a JMessageLogger object to be used in multi-thread environment.

Member Function Documentation

typeout() [1/2]

virtual void JLOGGER::JMessageLoggerThreadSafe::typeout ( const std::string & tag, const std::string & message )

inlineoverridevirtual

Report message.

Parameters

tag	tag
message	message

Reimplemented from JLOGGER::JMessageLogger.

Definition at line 272 of file JMessageLogger.hh.

    {
      JSYNCHRONIZATION::JMutex::JScopedLock lock(logger->mutex());
      logger->typeout(tag, message);
    }

reset()

void JLOGGER::JMessageLogger::reset ( JLogger * __logger = NULL )

inlineinherited

Reset logger.

Parameters

__logger

pointer to logger

Definition at line 105 of file JMessageLogger.hh.

    {
      logger.reset(__logger);
    }

getLevel()

JLevel_t JLOGGER::JMessageLogger::getLevel ( )

inlineinherited

Get debug level.

Returns

debug level

Definition at line 116 of file JMessageLogger.hh.

    {
      return level;
    }

setLevel() [1/2]

void JLOGGER::JMessageLogger::setLevel ( const int __level )

inlineinherited

Set debug level.

Parameters

__level

debug level

Definition at line 127 of file JMessageLogger.hh.

    {
      if      (__level <  0)
        level = OFF;
      else if (__level == 0)
        level = ERROR;

Report message.

Parameters

__level	level
__prefix	prefix
__message	message
