Member Function Documentation

size_t Ef_OutputValueCache::ExclusiveAccess::Clear ( )
inline

Clears the entire cache. Returns the number of bytes that have been removed from the cache.

Definition at line 131 of file outputValueCache.h.

VdfRequest Ef_OutputValueCache::ExclusiveAccess::GetUncached ( const VdfRequest &  request) const
inline

Returns a request of outputs that are not currently cached.

Definition at line 85 of file outputValueCache.h.

const VdfVector* Ef_OutputValueCache::ExclusiveAccess::GetValue ( const VdfOutput &  output,
const VdfMask &  mask 
) const
inline

Returns the cached value for a given output and mask, if it exists.

Definition at line 93 of file outputValueCache.h.

size_t Ef_OutputValueCache::ExclusiveAccess::Invalidate ( const VdfOutput &  output)
inline

Invalidate an output by removing all the data stored at the output. Returns the number of bytes invalidated.

Definition at line 116 of file outputValueCache.h.

size_t Ef_OutputValueCache::ExclusiveAccess::Invalidate ( const VdfMaskedOutputVector &  outputs)
inline

Invalidate a vector of outputs and masks by removing the data from the cache. Returns the number of bytes invalidated.

Definition at line 124 of file outputValueCache.h.

bool Ef_OutputValueCache::ExclusiveAccess::IsEmpty ( ) const
inline

Returns true if the cache is empty at this time.

Definition at line 71 of file outputValueCache.h.

bool Ef_OutputValueCache::ExclusiveAccess::IsUncached ( const VdfRequest &  request) const
inline

Returns true if any outputs in the request are not currently cached.

Definition at line 78 of file outputValueCache.h.

const ExclusiveAccess& Ef_OutputValueCache::ExclusiveAccess::operator= ( const ExclusiveAccess &  )
delete
size_t Ef_OutputValueCache::ExclusiveAccess::SetValue ( const VdfOutput &  output,
const VdfVector &  value,
const VdfMask &  mask 
)
inline

Sets the cached values for a given output and mask. Returns the number of bytes of additionally allocated storage.

This will NOT update elements in the vector, which are already cached. Only uncached data will be merged into values existing in the cache.
