Member Function Documentation

static DtCachedIntersectorManager& makVrv::DtCachedIntersectorManager::instance ( DtDe & de ) [static]

Get the creator instance for this IG object.

Exceptions:

DtCorruptedState if it is unable to get the instance.

static void makVrv::DtCachedIntersectorManager::registerInstance	(	DtDe &	de,
		DtCachedIntersectorManager *	anInstance
	)		`[static]`

Register the creator instance with an IG.

DtCachedIntersector& makVrv::DtCachedIntersectorManager::modelSetIntersector ( int modelSet )

Get a intersector for a particular model set.

virtual void makVrv::DtCachedIntersectorManager::setShareIntersectionResults ( bool ) [virtual]

Set to have results shared or specific for model set.

If shared will use a pointer allocated and managed by this class. If by specific model set, each model set will have it's own cache. The default is to share

bool makVrv::DtCachedIntersectorManager::shareIntersectionResults ( ) const

virtual void makVrv::DtCachedIntersectorManager::setCacheIsPermanent ( bool ) [virtual]

Sets whether or not cache is permanent.

If it is, can optionally set the size of the cache (default is 1000 points). If not permanent, then the time to clear out can be set (default is every tick). Enter time in number of milliseconds

bool makVrv::DtCachedIntersectorManager::cacheIsPermanent ( ) const

Returns whether or not cache is permenant.

virtual void makVrv::DtCachedIntersectorManager::setCacheLimit ( int ) [virtual]

Sets the limit on the number of items that can be in the cache.

int makVrv::DtCachedIntersectorManager::cacheLimit ( ) const

Returns the limit on the cache.

virtual void makVrv::DtCachedIntersectorManager::setCacheClearTime ( double ) [virtual]

Sets the time (in milliseconds) to clear out the cache. Default is to clear each tick.

double makVrv::DtCachedIntersectorManager::cacheClearTime ( ) const

Returns the cache clear time.

virtual void makVrv::DtCachedIntersectorManager::onPostTick ( ) [protected, virtual]

Will check to see if cache needs to be cleared.
