void AdaptiveLruPage::dequeue_lru ( ) [inline, inherited]
void AdaptiveLruPage::enqueue_lru ( AdaptiveLru lru) [inherited]
void DXTextureContext9::evict_lru ( ) [virtual]

Evicts the page from the LRU.

Called internally when the LRU determines that it is full. May also be called externally when necessary to explicitly evict the page.

It is legal for this method to either evict the page as requested, do nothing (in which case the eviction will be requested again at the next epoch), or requeue itself on the tail of the queue (in which case the eviction will be requested again much later).

Reimplemented from AdaptiveLruPage.
