question: public void incrStats ( Collection < GraphNode > nodes ) { totalCount += nodes . size ( ) ; for ( GraphNode node : nodes ) { ElementKindDescriptor descr = findDescriptor ( node ) ; if ( null == descr ) { otherCount ++ ; } else { int count = kindCounts . get ( descr ) ; kindCounts . put ( descr , count + 1 ) ; } } }
target:  Update the current statistics for the new set of analysis nodes.
