Constructor & Destructor Documentation

◆ vtkTextureImageCache()

template<class Key >

vtkTextureImageCache< Key >::vtkTextureImageCache ( )

inline

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

Member Function Documentation

◆ IsKeyInCache()

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 115 of file vtkOpenGLContextDevice2DPrivate.h.

◆ GetCacheData()

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.
