Detailed Description

Enumerates the SceneManager classes available to applications.

Remarks: As described in the SceneManager class, SceneManagers are responsible for organising the scene and issuing rendering commands to the RenderSystem. Certain scene types can benefit from different rendering approaches, and it is intended that subclasses will be created to special case this.

: In order to give applications easy access to these implementations, this class has a number of methods to create or retrieve a SceneManager which is appropriate to the scene type.

: SceneManagers are created by SceneManagerFactory instances. New factories for new types of SceneManager can be registered with this class to make them available to clients.

: Note that you can still plug in your own custom SceneManager without using a factory, should you choose, it's just not as flexible that way. Just instantiate your own SceneManager manually and use it directly.

Member Function Documentation

void Ogre::SceneManagerEnumerator::addFactory ( SceneManagerFactory * fact )

Register a new SceneManagerFactory.

Remarks: Plugins should call this to register as new SceneManager providers.

SceneManager* Ogre::SceneManagerEnumerator::createSceneManager	(	const String &	typeName,
		const String &	instanceName = `StringUtil::BLANK`
	)

Create a SceneManager instance of a given type.

Remarks: You can use this method to create a SceneManager instance of a given specific type. You may know this type already, or you may have discovered it by looking at the results from getMetaDataIterator.

Note: This method throws an exception if the named type is not found.

Parameters

typeName	String identifying a unique SceneManager type
instanceName	Optional name to given the new instance that is created. If you leave this blank, an auto name will be assigned.

SceneManager* Ogre::SceneManagerEnumerator::createSceneManager	(	SceneTypeMask	typeMask,
		const String &	instanceName = `StringUtil::BLANK`
	)

Create a SceneManager instance based on scene type support.

Remarks: Creates an instance of a SceneManager which supports the scene types identified in the parameter. If more than one type of SceneManager has been registered as handling that combination of scene types, in instance of the last one registered is returned.

Note: This method always succeeds, if a specific scene manager is not found, the default implementation is always returned.

Parameters

typeMask	A mask containing one or more SceneType flags
instanceName	Optional name to given the new instance that is created. If you leave this blank, an auto name will be assigned.

void Ogre::SceneManagerEnumerator::destroySceneManager ( SceneManager * sm )

Destroy an instance of a SceneManager.

const SceneManagerMetaData* Ogre::SceneManagerEnumerator::getMetaData ( const String & typeName ) const

Get more information about a given type of SceneManager.

Remarks: The metadata returned tells you a few things about a given type of SceneManager, which can be created using a factory that has been registered already.

Parameters

typeName The type name of the SceneManager you want to enquire on. If you don't know the typeName already, you can iterate over the metadata for all types using getMetaDataIterator.

MetaDataIterator Ogre::SceneManagerEnumerator::getMetaDataIterator ( void ) const

Iterate over all types of SceneManager available for construction, providing some information about each one.

SceneManager* Ogre::SceneManagerEnumerator::getSceneManager ( const String & instanceName ) const

Get an existing SceneManager instance that has already been created, identified by the instance name.

Parameters

instanceName The name of the instance to retrieve.

SceneManagerIterator Ogre::SceneManagerEnumerator::getSceneManagerIterator ( void )

Get an iterator over all the existing SceneManager instances.

static SceneManagerEnumerator& Ogre::SceneManagerEnumerator::getSingleton ( void )

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.

static SceneManagerEnumerator* Ogre::SceneManagerEnumerator::getSingletonPtr ( void )

bool Ogre::SceneManagerEnumerator::hasSceneManager ( const String & instanceName ) const

Identify if a SceneManager instance already exists.

Parameters

instanceName The name of the instance to retrieve.
