Detailed Description

The SoCacheElement class stores and manages the open caches.


Constructor & Destructor Documentation

SoCacheElement::~SoCacheElement ( void  ) [protected, virtual]

The destructor.


Member Function Documentation

void SoCacheElement::initClass ( void  ) [static]

Initialize relevant common data for all instances, like the type system.

Reimplemented from SoElement.

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

Sets the current cache. The cache is ref'ed before returning.

SoCache * SoCacheElement::getCache ( void  ) const

This method returns the cache, or NULL if there is no cache.

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

This method returns TRUE if a cache is currently open.

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

This method invalidates open caches. It should be called by uncacheable nodes.

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

SoCacheElement objects should not be "copied" because you obviously don't cache them in the cache.

See also:
SbBool SoCacheElement::matches(const SoElement * element) const

Implements SoElement.

SoCacheElement * SoCacheElement::getNextCacheElement ( void  ) const

This method returns the next cache element. That is the next cache element pointing towards the bottom of the state.

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

This method adds element to the elements used lists of all the open caches in state.

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

This method creates dependencies on cache for all the open caches in state.

SbBool SoCacheElement::setInvalid ( const SbBool  newvalue) [static]

This method returns the old invalidated bit value, and sets it to newvalue.

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

This method returns the current cache. No cache dependencies are honored.
