Interface GDateSpecification

All Known Implementing Classes:
GDate, GDateBuilder

public interface GDateSpecification
Represents an XML Schema-compatible Gregorian date.

Both the immutable GDate and the mutable GDateBuilder are GDateSpecifications. Use this interface where you want to allow callers to pass any implementation of a GDate.

  • Field Details

  • Method Details

    • getFlags

    • isImmutable

      boolean isImmutable()
      True if this GDate specification is immutable. GDate returns true, and GDateBuilder returns false.
    • isValid

      boolean isValid()
      True if this GDate corresponds to a valid gregorian date value in XML schema.
    • hasTimeZone

      boolean hasTimeZone()
      True if this date/time specification specifies a timezone.
    • hasYear

      boolean hasYear()
      True if this date/time specification specifies a year.
    • hasMonth

      boolean hasMonth()
      True if this date/time specification specifies a month-of-year.
    • hasDay

      boolean hasDay()
      True if this date/time specification specifies a day-of-month.
    • hasTime

      boolean hasTime()
      True if this date/time specification specifies a time-of-day.
    • hasDate

      boolean hasDate()
      True if this date/time specification specifies a full date (year, month, day)
    • getYear

      int getYear()
      Gets the year. Should be a four-digit year specification.
    • getMonth

      int getMonth()
      Gets the month-of-year. January is 1.
    • getDay

      int getDay()
      Gets the day-of-month. The first day of each month is 1.
    • getHour

      int getHour()
      Gets the hour-of-day. Midnight is 0, and 11PM is 23.
    • getMinute

      int getMinute()
      Gets the minute-of-hour. Range from 0 to 59.
    • getSecond

      int getSecond()
      Gets the second-of-minute. Range from 0 to 59.
    • getTimeZoneSign

      int getTimeZoneSign()
      Gets the time zone sign. For time zones east of GMT, this is positive; for time zones west, this is negative.
    • getTimeZoneHour

      int getTimeZoneHour()
      Gets the time zone hour. This is always positive: for the sign, look at getTimeZoneSign().
    • getTimeZoneMinute

      int getTimeZoneMinute()
      Gets the time zone minutes. This is always positive: for the sign, look at getTimeZoneSign().
    • getFraction

      BigDecimal getFraction()
      Gets the fraction-of-second. Range from 0 (inclusive) to 1 (exclusive).
    • getMillisecond

      int getMillisecond()
      Gets the rounded millisecond value. Range from 0 to 999
    • getJulianDate

      int getJulianDate()
      Returns the Julian date corresponding to this Gregorian date. The Julian date (JD) is a continuous count of days from 1 January 4713 BC.
    • getCalendar

      XmlCalendar getCalendar()
      Retrieves the value of the current time as an XmlCalendar.

      XmlCalendar is a subclass of GregorianCalendar which is slightly customized to match XML schema date rules.

      The returned XmlCalendar has only those time and date fields set that are reflected in the GDate object. Because of the way the Calendar contract works, any information in the isSet() vanishes as soon as you view any unset field using get() methods. This means that if it is important to understand which date fields are set, you must call isSet() first before get().

    • getDate

      Date getDate()
      Retrieves the value of the current time as a java.util.Date instance.
    • compareToGDate

      int compareToGDate(GDateSpecification gdatespec)
      Comparison to another GDate.
      • Returns -1 if this < date. (less-than)
      • Returns 0 if this == date. (equal)
      • Returns 1 if this > date. (greater-than)
      • Returns 2 if this <> date. (incomparable)
      Two instances are incomparable if they have different amounts of information.
      Parameters:
      gdatespec - the date to compare against.
    • getBuiltinTypeCode

      int getBuiltinTypeCode()
      Returns the builtin type code for the shape of the information contained in this instance, or 0 if the instance doesn't contain information corresponding to a Schema type.

      Value will be equal to SchemaType.BTC_NOT_BUILTIN, SchemaType.BTC_G_YEAR, SchemaType.BTC_G_YEAR_MONTH, SchemaType.BTC_G_MONTH, SchemaType.BTC_G_MONTH_DAY, SchemaType.BTC_G_DAY, SchemaType.BTC_DATE, SchemaType.BTC_DATE_TIME, or SchemaType.BTC_TIME.

    • canonicalString

      String canonicalString()
      The canonical string representation. Specific moments or times-of-day in a specified timezone are normalized to UTC time to produce a canonical string form for them. Other recurring time specifications keep their timezone information.
    • toString

      String toString()
      The natural string representation. This represents the information that is available, including timezone. For types that correspond to defined schema types (schemaBuiltinTypeCode() > 0), this provides the natural lexical representation. When both time and timezone are specified, this string is not the canonical representation unless the timezone is UTC (Z) (since the same moment in time can be expressed in different timezones). To get a canonical string, use the canonicalString() method.
      Overrides:
      toString in class Object
