cache_region_if_needed()

void MayaFlux::Kakshya::RegionProcessorBase::cache_region_if_needed ( const RegionSegment &  segment, const std::shared_ptr< SignalSourceContainer > &  container  )

protectedvirtual

Cache a region's data if beneficial and not already cached.

Uses heuristics (e.g., segment size vs. cache size) to decide.

Parameters

segment	The region segment to consider for caching.
container	The container providing the data.
