Detailed Description

template<class Types>
class CYapfSegmentCostCacheLocalT< Types >

CYapfSegmentCostCacheLocalT - the yapf cost cache provider that implements fake segment cost caching functionality for yapf.

Used when node needs caching, but you don't want to cache the segment costs.

Definition at line 41 of file yapf_costcache.hpp.


Member Function Documentation

template<class Types>
FORCEINLINE bool CYapfSegmentCostCacheLocalT< Types >::PfNodeCacheFetch ( Node n  )  [inline]

Called by YAPF to attach cached or local segment cost data to the given node.

Returns:
true if globally cached data were used or false if local data was used

Reimplemented in CYapfSegmentCostCacheGlobalT< Types >.

template<class Types>
FORCEINLINE void CYapfSegmentCostCacheLocalT< Types >::PfNodeCacheFlush ( Node n  )  [inline]

Called by YAPF to flush the cached segment cost data back into cache storage.

Current cache implementation doesn't use that.

Reimplemented in CYapfSegmentCostCacheGlobalT< Types >.
