Constructor & Destructor Documentation

◆ SoCache()

SoCache::SoCache ( SoState * state )

Takes the state in effect when the cache is used; it is assumed that the state is pushed before the cache is created.

Referenced by addCacheDependency().

◆ ~SoCache()

virtual SoCache::~SoCache ( )

Member Function Documentation

◆ addCacheDependency()

virtual void SoCache::addCacheDependency	(	const SoState *	state,
		SoCache *	cache )

virtual

The default method takes care of adding dependencies from the child cache.

References SoCache().

◆ addElement()

void SoCache::addElement ( const SoElement * elt )

◆ destroy()

virtual void SoCache::destroy ( SoState * state )

protectedvirtual

Render caches use this to free display lists. Note that the state will be NULL if the cache is no deleted during the application of an action.

Reimplemented in SoGLRenderCache.

◆ getInvalidElement()

const SoElement * SoCache::getInvalidElement ( const SoState * state ) const

Returns NULL if the cache is not invalid because of an element or if the cache is valid.

◆ invalidate()

void SoCache::invalidate ( )

◆ isValid()

virtual bool SoCache::isValid ( const SoState * state ) const

virtual

Reimplemented in SoGLRenderCache.

◆ ref()

void SoCache::ref ( )

◆ unref()

void SoCache::unref ( SoState * state = NULL )
