Example 11 with DurationField

use of org.joda.time.DurationField in project joda-time by JodaOrg.

the class BaseSingleFieldPeriod method standardPeriodIn.

/**
     * Creates a new instance representing the number of complete standard length units
     * in the specified period.
     * <p>
     * This factory method converts all fields from the period to hours using standardised
     * durations for each field. Only those fields which have a precise duration in
     * the ISO UTC chronology can be converted.
     * <ul>
     * <li>One week consists of 7 days.
     * <li>One day consists of 24 hours.
     * <li>One hour consists of 60 minutes.
     * <li>One minute consists of 60 seconds.
     * <li>One second consists of 1000 milliseconds.
     * </ul>
     * Months and Years are imprecise and periods containing these values cannot be converted.
     *
     * @param period  the period to get the number of hours from, must not be null
     * @param millisPerUnit  the number of milliseconds in one standard unit of this period
     * @throws IllegalArgumentException if the period contains imprecise duration values
