Protected Member Functions inherited from SoCache
virtual ~SoCache ()

SoGLRenderCache::SoGLRenderCache (SoState * state)¶

Constructor with state being the current state.

SoGLRenderCache::~SoGLRenderCache () [virtual]¶

Destructor.

void SoGLRenderCache::open (SoState * state)¶

Opens the cache. All GL calls will be cached until close() is called.

See also

void SoGLRenderCache::close (void)¶

Closes the cache. Should be called after all GL calls.

See also

void SoGLRenderCache::call (SoState * state)¶

Executes the cached display list.

See also

int SoGLRenderCache::getCacheContext (void) const¶

Returns the cache context of this cache. This is used to quickly determine if cache can be used for a state.

This method is an extension versus the Open Inventor API.

SbBool SoGLRenderCache::isValid (const SoState * state) const [virtual]¶

Return TRUE if this cache is valid, FALSE otherwise.

Reimplemented from SoCache.

void SoGLRenderCache::addNestedCache (SoGLDisplayList * child) [virtual]¶

Adds a display list which is called from this cache. This is to make sure the child display list isn't destroyed too early.

void SoGLRenderCache::destroy (SoState * state) [protected], [virtual]¶

Can be overridden by subclasses to clean up before they are deleted. Default method does nothing.

Reimplemented from SoCache.
