Element that stores the most recently opened cache.

Inheritance diagram for SoCacheElement:

Public Member Functions
virtual void	init (SoState *state)
	Initializes element.
SoCache *	getCache () const
	Returns the cache stored in an instance. This may be NULL.
virtual void	pop (SoState state, const SoElement prevTopElement)
	Overrides this method to unref cache.
virtual SbBool	matches (const SoElement *elt) const
	Overrides this method to print an error message and return FALSE.
virtual SoElement *	copyMatchInfo () const
	Copy method prints error and returns NULL; see comment above.
SoCacheElement *	getNextCacheElement () const
	Returns the next cache element in the stack.
virtual	~SoCacheElement ()
Static Public Member Functions
static void	set (SoState state, SoCache cache)
	Sets cache in element accessed from state.
static SbBool	anyOpen (SoState *state)
	Returns TRUE if any cache is currently open in the state.
static void	invalidate (SoState *state)
	Invalidate any open caches.
static void	initClass ()
	Initializes the SoCacheElement class.
static void	addElement (SoState state, const SoElement elt)
	Adds the given element to the elements used lists of all currently open caches in the state.
static void	addCacheDependency (SoState state, SoCache cache)
	Adds a dependency on the given cache to all currently open caches in the state.
static SbBool	setInvalid (SbBool newValue)
	Sets invalidated bit, and returns its old value.
static SoCache *	getCurrentCache (SoState *state)
	returns the current cache, from the top of the stack.

Constructor & Destructor Documentation

virtual SoCacheElement::~SoCacheElement ( ) [virtual]

static void SoCacheElement::addCacheDependency	(	SoState *	state,
		SoCache *	cache
	)		`[static]`

static void SoCacheElement::addElement	(	SoState *	state,
		const SoElement *	elt
	)		`[static]`

static SbBool SoCacheElement::anyOpen ( SoState * state ) [static]

virtual SoElement* SoCacheElement::copyMatchInfo ( ) const [virtual]

Implements SoElement.

SoCache* SoCacheElement::getCache ( ) const [inline]

Definition at line 83 of file SoCacheElement.h.

static SoCache* SoCacheElement::getCurrentCache ( SoState * state ) [inline, static]

Does not cause a cache dependence like getConstElement().

Definition at line 125 of file SoCacheElement.h.

SoCacheElement* SoCacheElement::getNextCacheElement ( ) const [inline]

Definition at line 104 of file SoCacheElement.h.

virtual void SoCacheElement::init ( SoState * state ) [virtual]

Reimplemented from SoElement.

static void SoCacheElement::initClass ( ) [static]

Reimplemented from SoElement.

static void SoCacheElement::invalidate ( SoState * state ) [static]

This is called by nodes that should not be cached.

virtual SbBool SoCacheElement::matches ( const SoElement * elt ) const [virtual]

Cache elements should never be compared, since they never appear in the elements-used list of caches!

Implements SoElement.

virtual void SoCacheElement::pop	(	SoState *	state,
		const SoElement *	prevTopElement
	)		`[virtual]`

Reimplemented from SoElement.

static void SoCacheElement::set	(	SoState *	state,
		SoCache *	cache
	)		`[static]`

static SbBool SoCacheElement::setInvalid ( SbBool newValue ) [static]

Used by SoGLCacheList so auto-caching doesn't cache too much.
