    • add

      public long add(long instant, int value)
      Description copied from class: BaseDateTimeField
      Adds a value (which may be negative) to the instant value, overflowing into larger fields if necessary.

      The value will be added to this field. If the value is too large to be added solely to this field, larger fields will increase as required. Smaller fields should be unaffected, except where the result would be an invalid value for a smaller field. In this case the smaller field is adjusted to be in range.

      For example, in the ISO chronology:
      2000-08-20 add six months is 2001-02-20
      2000-08-20 add twenty months is 2002-04-20
      2000-08-20 add minus nine months is 1999-11-20
      2001-01-31 add one month is 2001-02-28
      2001-01-31 add two months is 2001-03-31

      Overrides:
      add in class BaseDateTimeField
      Parameters:
      instant - the milliseconds from 1970-01-01T00:00:00Z to add to
      value - the value to add, in the units of the field
      Returns:
      the updated milliseconds

    • add

      public long add(long instant, long value)
      Description copied from class: BaseDateTimeField
      Adds a value (which may be negative) to the instant value, overflowing into larger fields if necessary.
      Overrides:
      add in class BaseDateTimeField
      Parameters:
      instant - the milliseconds from 1970-01-01T00:00:00Z to add to
      value - the long value to add, in the units of the field
      Returns:
      the updated milliseconds
      See Also:

    • add

      public int[] add(ReadablePartial partial, int fieldIndex, int[] values, int valueToAdd)
      Description copied from class: BaseDateTimeField
      Adds a value (which may be negative) to the partial instant, throwing an exception if the maximum size of the instant is reached.

      The value will be added to this field, overflowing into larger fields if necessary. Smaller fields should be unaffected, except where the result would be an invalid value for a smaller field. In this case the smaller field is adjusted to be in range.

      Partial instants only contain some fields. This may result in a maximum possible value, such as TimeOfDay being limited to 23:59:59:999. If this limit is breached by the add an exception is thrown.

      For example, in the ISO chronology:
      2000-08-20 add six months is 2000-02-20
      2000-08-20 add twenty months is 2000-04-20
      2000-08-20 add minus nine months is 2000-11-20
      2001-01-31 add one month is 2001-02-28
      2001-01-31 add two months is 2001-03-31

      Overrides:
      add in class BaseDateTimeField
      Parameters:
      partial - the partial instant
      fieldIndex - the index of this field in the partial
      values - the values of the partial instant which should be updated
      valueToAdd - the value to add, in the units of the field
      Returns:
      the passed in values

    • getDifference

      public int getDifference(long minuendInstant, long subtrahendInstant)
      Description copied from class: BaseDateTimeField
      Computes the difference between two instants, as measured in the units of this field. Any fractional units are dropped from the result. Calling getDifference reverses the effect of calling add. In the following code:

      minuendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract from
      subtrahendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract off the minuend

      the difference in the units of this field

    • getDifferenceAsLong

      public long getDifferenceAsLong(long minuendInstant, long subtrahendInstant)
      Description copied from class: BaseDateTimeField
      Computes the difference between two instants, as measured in the units of this field. Any fractional units are dropped from the result. Calling getDifference reverses the effect of calling add. In the following code: 
       long instant = ...
 long v = ...
 long age = getDifferenceAsLong(add(instant, v), instant);
      The value 'age' is the same as the value 'v'.
      Overrides:

      Parameters:
      minuendInstant - the milliseconds from 1970-01-01T00:00:00Z to subtract from

      Returns:
      the difference in the units of this field

    • set

      public long set(long instant, int value)
      Description copied from class: BaseDateTimeField
      Sets a value in the milliseconds supplied.

      The value of this field will be set. If the value is invalid, an exception if thrown.

      If setting this field would make other fields invalid, then those fields may be changed. For example if the current date is the 31st January, and the month is set to February, the day would be invalid. Instead, the day would be changed to the closest value - the 28th/29th February as appropriate.

      Specified by:
      set in class BaseDateTimeField
      Parameters:
      instant - the milliseconds from 1970-01-01T00:00:00Z to set in

      This implementation uses convertText(String, Locale) and BaseDateTimeField.set(long, int).

      Note: subclasses that override this method should also override getAsText.

      Overrides:
      set in class BaseDateTimeField
      Parameters:
      instant - the milliseconds from 1970-01-01T00:00:00Z to set in
