Detailed Description

The log manager handles the creation and retrieval of logs for the application.

Remarks

This class will create new log files and will retrieve instances of existing ones. Other classes wishing to log output can either create a fresh log or retrieve an existing one to output to. One log is the default log, and is the one written to when the logging methods of this class are called.

By default, Root will instantiate a LogManager (which becomes the Singleton instance) on construction, and will create a default log based on the Root construction parameters. If you want more control, for example redirecting log output right from the start or suppressing debug output, you need to create a LogManager yourself before creating a Root instance, then create a default log. Root will detect that you've created one yourself and won't create one of its own, thus using all your logging preferences from the first instance.

Member Function Documentation

createLog()

Log* Ogre::LogManager::createLog	(	const String &	name,
		bool	defaultLog = false,
		bool	debuggerOutput = true,
		bool	suppressFileOutput = false
	)

Creates a new log with the given name.

Parameters

name	The name to give the log e.g. 'Ogre.log'
defaultLog	If true, this is the default log output will be sent to if the generic logging methods on this class are used. The first log created is always the default log unless this parameter is set.
debuggerOutput	If true, output to this log will also be routed to the debugger's output window.
suppressFileOutput	If true, this is a logical rather than a physical log and no file output will be written. If you do this you should register a LogListener so log output is not lost.

destroyLog() [1/2]

void Ogre::LogManager::destroyLog

(

const String &

name

)

Closes and removes a named log.

destroyLog() [2/2]

void Ogre::LogManager::destroyLog

(

Log *

log

)

Closes and removes a log.

getDefaultLog()

Log* Ogre::LogManager::getDefaultLog

(

)

Returns a pointer to the default log.

getLog()

Log* Ogre::LogManager::getLog

(

const String &

name

)

Retrieves a log managed by this class.

getSingleton()

static LogManager& Ogre::LogManager::getSingleton ( )

static

Override standard Singleton retrieval.

Remarks

Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.

This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

getSingletonPtr()

static LogManager* Ogre::LogManager::getSingletonPtr ( )

static

Override standard Singleton retrieval.
