factoryReset

public void factoryReset()

Description copied from interface: ResourceFactoryListener

Called when the factory is lost and about to be reset. This may result in some of the vram based resources becoming invalid. The listeners can chose which resources to let go of depending on whether they're based in vram.

Specified by:

factoryReset in interface ResourceFactoryListener

factoryReleased

public void factoryReleased()

Description copied from interface: ResourceFactoryListener

Called when the factory is released. This may result in all resources becoming invalid. The listeners should let go of all resources created from this factory.

Specified by:

factoryReleased in interface ResourceFactoryListener
