Detailed Description

template<class Key>
class vtkTextureImageCache< Key >

Definition at line 48 of file vtkOpenGLContextDevice2DPrivate.h.

Constructor & Destructor Documentation

template<class Key>
vtkTextureImageCache< Key >::vtkTextureImageCache ( )
inline

Construct a texture image cache with a maximum number of texture of

Definition at line 86 of file vtkOpenGLContextDevice2DPrivate.h.

Member Function Documentation

template<class Key>
bool vtkTextureImageCache< Key >::IsKeyInCache ( const Key &  key) const
inline

Search the cache list to see if a given key already exists. Returns true if the key is found, false otherwise.

Definition at line 95 of file vtkOpenGLContextDevice2DPrivate.h.

template<class Key>
vtkTextureImageCache< Key >::CacheData & vtkTextureImageCache< Key >::GetCacheData ( const Key &  key)

Return the cache associated to a key. If the key doesn't exist yet in the cache list, create a new cache. The returned cache is moved at the begining of the cache list for faster search next time. The most use cache is faster to be searched.

template<class Key>
void vtkTextureImageCache< Key >::ReleaseGraphicsResources ( vtkWindow window)
inline

Release all the OpenGL Pixel Buffer Object(PBO) associated with the textures of the cache list.

template<class Key>
CacheData& vtkTextureImageCache< Key >::AddCacheData ( const Key &  key,
const CacheData cacheData 
)
inlineprotected

Add a new cache entree into the cache list. Enforce the MaxSize size of the list by removing the least used cache if needed.
