question: convert a duration to the number of nanoseconds . concode_field_sep long DURATION_SECONDS_MAX concode_elem_sep long DURATION_SECONDS_MIN concode_field_sep Duration add concode_elem_sep Duration fromNanos concode_elem_sep Duration fromMillis concode_elem_sep boolean isValid concode_elem_sep boolean isValid concode_elem_sep void checkValid concode_elem_sep Duration subtract concode_elem_sep Duration fromMicros concode_elem_sep String toString concode_elem_sep long toMillis concode_elem_sep Duration parse concode_elem_sep long toMicros concode_elem_sep Duration normalizedDuration
target: long function ( Duration arg0 ) { return arg0 . getSeconds ( ) * NANOS_PER_SECOND + arg0 . getNanos ( ) ; }
