public void received ( final long offset , final long size ) { final Pair < CAddress , Long > pair = Pair . make ( new CAddress ( offset ) , size ) ; if ( lastMemoryRequest . contains ( pair ) ) { lastMemoryRequest . remove ( pair ) ; } }
this function must be called to tell the memory loader that a reply for a certain request was received . only after this request arrived , new requests with the same offset / size pair can be issued .
