question: private void addBlockBasedOnMinMaxValue ( FilterExecuter filterExecuter , List < DataRefNode > listOfDataBlocksToScan , DataRefNode dataRefNode , SegmentProperties segmentProperties ) { BitSet bitSet = filterExecuter . isScanRequired ( dataRefNode . getColumnsMaxValue ( ) , dataRefNode . getColumnsMinValue ( ) ) ; if ( ! bitSet . isEmpty ( ) ) { listOfDataBlocksToScan . add ( dataRefNode ) ; } }
target:  Selects the blocks based on col max and min value.
