Detailed Description

Provides asynchronous message logging.

The asynchronous appender servers as a proxy object for the logger and is useful when a particular appender takes considerable time to process a message.

The asynchronous appender maintains a list of other registered appenders and forwards them a message in a separate thread.

The message is delivered to the appenders in the order they were registered in the asynchronous appender.

Member Function Documentation

Register()

void cadex::Base_LoggerAsyncAppender::Register	(	Base_LoggerAppender &	theAppender,
		const Base_Logger::Level	theMinLevel = Base_Logger::Trace,
		const Base_Logger::Level	theMaxLevel = Base_Logger::Fatal
	)

Adds an appender.

The life span of theAppender must be greater than on of this object, otherwise it must be explicitly unregistered with Unregister().
