Constructor & Destructor Documentation

SoGLRenderCache::SoGLRenderCache ( SoState state  ) 

Constructor with state being the current state.

SoGLRenderCache::~SoGLRenderCache (  )  [virtual]

Destructor.


Member Function Documentation

void SoGLRenderCache::open ( SoState state  ) 

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

See also:
close()

call()

void SoGLRenderCache::close ( void   ) 

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

See also:
open()

void SoGLRenderCache::call ( SoState state  ) 

Executes the cached display list.

See also:
open()

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.
