vtkTextureImageCache< Key >::vtkTextureImageCache | ( | ) | [inline] |
Construct a texture image cache with a maximum number of texture of 50.
Definition at line 86 of file vtkOpenGLContextDevice2DPrivate.h.
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.

vtkTextureImageCache< Key >::CacheData & vtkTextureImageCache< Key >::GetCacheData | ( | const Key & | key | ) | [inline] |
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.

void vtkTextureImageCache< Key >::ReleaseGraphicsResources | ( | vtkWindow * | window | ) | [inline] |
Release all the OpenGL Pixel Buffer Object(PBO) associated with the textures of the cache list.

CacheData& vtkTextureImageCache< Key >::AddCacheData | ( | const Key & | key, | |
const CacheData & | cacheData | |||
) | [inline, protected] |
Add a new cache entree into the cache list. Enforce the MaxSize size of the list by removing the least used cache if needed.
