Constructor & Destructor Documentation

template<class Key>

vtkTextureImageCache< Key >::vtkTextureImageCache ( ) [inline]

Construct a texture image cache with a maximum number of texture of 50.

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 97 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.

Definition at line 148 of file vtkOpenGLContextDevice2DPrivate.h.

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.
