Constructor & Destructor Documentation

KfTransformArrayMemoryManager()

Ogre::KfTransformArrayMemoryManager::KfTransformArrayMemoryManager	(	uint16	depthLevel,
		size_t	hintMaxNodes,
		size_t	cleanupThreshold = 100,
		size_t	maxHardLimit = MAX_MEMORY_SLOTS,
		RebaseListener *	rebaseListener = 0
	)

Constructor.

See intialize(). See destroy().

Parameters

elementsMemSize	Array containing the size in bytes of each element type (i.e. NodeElementsMemSize)
initRoutines	Array containing the cleanup function that will be called when default initializing memory. Unlike cleanupRoutines, just leave the function pointer null if all you want is just to initialize to 0.
cleanupRoutines	Array containing the cleanup function that will be called when performing cleanups. Many pointers can use the flatCleaner and is the fastest. However Array variables (i.e. ArrayVector3) have a layout where flatCleaner won't work correctly because the data is interleaved (rather than flat).
numElementsSize	Number of entries in elementsMemSize
depthLevel	Value only used to pass to the listener. Identifies to which hierarchy depth level this memory manager belongs to.
hintMaxNodes	Hint on how many SceneNodes we'll be creating.
cleanupThreshold	The threshold at which a cleanup is triggered after too many nodes have been destroyed in a non-LIFO order or without being created again. -1 to disable cleanups.
maxHardLimit	Maximum amount of SceneNodes. The manager is not allowed to grow and consume more memory past that limit. MAX_MEMORY_SLOTS for no limit. This is useful when target architecture has much less memory than the dev machine.

Note that if hintMaxNodes < maxHardLimit, the manager may be forced to do temporary allocations (to do the reallocs) thus during a brief perdiod of time it may consume more memory than the established hard limit (up to 2x).

Parameters

rebaseListener

The listener to be called when cleaning up or growing the memory pool. If null, cleanupThreshold is set to -1 & maxHardLimit will be set to hintMaxNodes

Member Function Documentation

createNewNode()

void Ogre::KfTransformArrayMemoryManager::createNewNode

(

KfTransform *RESTRICT_ALIAS *

outTransform

)

Requests memory for a new KfTransofrm (for the Array vectors & matrices)

Remarks

Uses all slots. Deletion is assumed to take place when the memory manager is destroyed; as this manager is run in a controlled environment.

Parameters

outTransform

Out: The transform with filled memory pointers
