Examples of javax.time.period.PeriodFields.toDuration()

javax.time.period.PeriodFields.toDuration()

Converts this {@code PeriodFields} to a {@code Duration} based on the standarddurations of seconds and nanoseconds.

The conversion is based on the {@code ISOChronology} definition of the seconds andnanoseconds units. If all the fields in this period can be converted to one of these units then the conversion will succeed, subject to calculation overflow. If any field cannot be converted to these fields above then an exception is thrown.

This conversion can only be used if the duration is being used in a manner compatible with the {@code ISOChronology} definitions of seconds and nanoseconds.This will be the case for most applications - care only needs to be taken if using explicit time-scales. @return the duration of this period based on {@code ISOChronology} fields, never null @throws ArithmeticException if the calculation overflows

     * @throws ArithmeticException if the calculation exceeds the capacity of {@code Instant}
     * @throws CalendricalException if the calculation exceeds the capacity of {@code ZonedDateTime}
