  • Method Details

    • isCivil

      boolean isCivil()
      Returns true if this object is using the fixed-cycle civil calendar, or false if using the religious, astronomical calendar.

    • getType

      IslamicCalendar.CalculationType getType()
      Return the type the algorithm implement.

    • epoch

      long monthStart(int year, int month)
      Return the day # on which the given month starts. Days are counted from the Hijri epoch, origin 0.
      Parameters:
      year - The hijri year
      month - The hijri month, 0-based

    • monthLength

      int monthLength(int year, int month)
      Return the length (in days) of the given month.

      Return the length (in days) of the given year.
      Parameters:
      year - The hijri year

    • compute

      void compute(long julianDays, long current, IntConsumer yearConsumer, IntConsumer monthConsumer, IntConsumer dayOfMonthConsumer, IntConsumer dayOfYearConsumer)
      Compute the year, month, dayOfMonth, and dayOfYear of the given julian days and current time and feed the caculuated results to the consumers.
      Parameters:
      julianDays -
      current - the time in millisecond.
      yearConsumer - consumer to take the year result.
      monthConsumer - consumer to take the month result.
      dayOfMonthConsumer - consumer to take the dayOfMonth result.
      dayOfYearConsumer - consumer to take the dayOfYear result.
