	Virtual destructor needed as class has virtual methods.

virtual bool	afterIlluminationPassesCreated (Technique *technique)
	Called right after illuminated passes were created, so that owner of runtime generated technique can handle this.

virtual bool	beforeIlluminationPassesCleared (Technique *technique)
	Called right before illuminated passes would be removed, so that owner of runtime generated technique can handle this.

	Called if a technique for a given scheme is not found within a material, allows the application to specify a Technique instance manually.

Detailed Description

Listener on any general material events.

Constructor & Destructor Documentation

virtual Ogre::MaterialManager::Listener::~Listener ( )

inlinevirtual

Virtual destructor needed as class has virtual methods.

virtual bool Ogre::MaterialManager::Listener::afterIlluminationPassesCreated ( Technique * technique )

inlinevirtual

Called right after illuminated passes were created, so that owner of runtime generated technique can handle this.

Returns: True if notification is handled and should not be propagated further.

virtual bool Ogre::MaterialManager::Listener::beforeIlluminationPassesCleared ( Technique * technique )

inlinevirtual

Called right before illuminated passes would be removed, so that owner of runtime generated technique can handle this.

Returns: True if notification is handled and should not be propagated further.

virtual Technique * Ogre::MaterialManager::Listener::handleSchemeNotFound	(	unsigned short	schemeIndex,
		const String &	schemeName,
		Material *	originalMaterial,
		unsigned short	lodIndex,
		const Renderable *	rend
	)

pure virtual

Called if a technique for a given scheme is not found within a material, allows the application to specify a Technique instance manually.

Remarks: Material schemes allow you to switch wholesale between families of techniques on a material. However they require you to define those schemes on the materials up-front, which might not be possible or desirable for all materials, particular if, for example, you wanted a simple way to replace all materials with another using a scheme.

: This callback allows you to handle the case where a scheme is requested but the material doesn't have an entry for it. You can return a Technique pointer from this method to specify the material technique you'd like to be applied instead, which can be from another material entirely (and probably will be). Note that it is critical that you only return a Technique that is supported on this hardware; there are utility methods like Material::getBestTechnique to help you with this.

Parameters

schemeIndex	The index of the scheme that was requested - all schemes have a unique index when created that does not alter.
schemeName	The friendly name of the scheme being requested
originalMaterial	The material that is being processed, that didn't have a specific technique for this scheme
lodIndex	The material level-of-detail that was being asked for, in case you need to use it to determine a technique.
rend	Pointer to the Renderable that is requesting this technique to be used, so this may influence your choice of Technique. May be null if the technique isn't being requested in that context.

Returns: A pointer to the technique to be used, or NULL if you wish to use the default technique for this material
