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 104 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 beginning of the cache list for faster search next time. The most use cache is faster to be searched.

Definition at line 155 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.

Definition at line 119 of file vtkOpenGLContextDevice2DPrivate.h.

template<class Key>

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

inlineprotected

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