Query()

virtual void BuildPatchServices::IChunkEvictionPolicy::Query ( const TMap< FGuid, TUniquePtr< IChunkDataAccess > > &  CurrentMap, int32  DesiredMax, TSet< FGuid > &  OutCleanable, TSet< FGuid > &  OutBootable  ) const

pure virtual

Query which chunks in a given set can be removed, or if necessary booted, in order to achieve the desired max count. It is possible to receive a decision of not evicting any data and thus expanding the data set past the desired max.

Parameters

CurrentMap	Reference to the full set of data to be considered.
DesiredMax	The maximum number of chunks desired for the set of data.
OutCleanable	Receives IDs for chunks which should be abandoned as they are no longer required.
OutBootable	Receives IDs for chunks which would be preferable to remove, but are still required later.

Implemented in BuildPatchServices::FChunkEvictionPolicy.
