TnFOX: FX::FXLRUCache::purgeLFU

template<class dictbase, class type>

virtual void FX::FXLRUCache< dictbase, type >::purgeLFU ( ) [inline, protected, virtual, inherited]

Called when totalCost() exceeds maxCost() to purge the least recently used items. The default implementation works on the basis of the least recently looked up via find(), however this is virtual so you can override it with a more intelligent mechanism
