question: ensures that this object is in the stopped state . if this object is in the running state , then this has the effect of adding to the total attribute the elapsed time since the last transition from stopped to running state and sets the running attribute to false . if this object is not in the running state , this call has no effect . concode_field_sep boolean running concode_elem_sep long total concode_elem_sep long startTime concode_elem_sep long lastStart concode_field_sep void zero concode_elem_sep long currentElapsedTime concode_elem_sep String currentElapsedTimeToMessage concode_elem_sep void start concode_elem_sep String toString concode_elem_sep void mark concode_elem_sep long elapsedTime concode_elem_sep String elapsedTimeToMessage
target: void function ( ) { if ( running ) { total += System . currentTimeMillis ( ) - startTime ; running = false ; } }
