Member Function Documentation
◆ allocate_ibuffer()
| void DXIndexBufferContext9::allocate_ibuffer | ( | DXScreenData & | scrn, |
| const GeomPrimitivePipelineReader * | reader | ||
| ) |
Allocates index buffer memory.
Definition at line 85 of file dxIndexBufferContext9.cxx.
References DXGraphicsStateGuardian9::get_index_type().
◆ create_ibuffer()
| void DXIndexBufferContext9::create_ibuffer | ( | DXScreenData & | scrn, |
| const GeomPrimitivePipelineReader * | reader | ||
| ) |
Creates a new index buffer (but does not upload data to it).
Definition at line 144 of file dxIndexBufferContext9.cxx.
◆ 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.
Definition at line 53 of file dxIndexBufferContext9.cxx.
References AdaptiveLruPage::dequeue_lru(), free_ibuffer(), IndexBufferContext::mark_unloaded(), and IndexBufferContext::update_data_size_bytes().
◆ free_ibuffer()
| void DXIndexBufferContext9::free_ibuffer | ( | void | ) |
Free index buffer.
Definition at line 64 of file dxIndexBufferContext9.cxx.
Referenced by evict_lru().
◆ upload_data()
| bool DXIndexBufferContext9::upload_data | ( | const GeomPrimitivePipelineReader * | reader, |
| bool | force | ||
| ) |
Copies the latest data from the client store to DirectX.
