Class SkipUndoDateTimeField

java.lang.Object
  org.joda.time.DateTimeField
      org.joda.time.field.DelegatedDateTimeField
          org.joda.time.field.SkipUndoDateTimeField

All Implemented Interfaces:

Serializable

public final class SkipUndoDateTimeField
extends DelegatedDateTimeField

Wraps another field such that a certain value is added back into the sequence of numbers.

This reverses the effect of SkipDateTimeField. This isn't very elegant.

SkipUndoDateTimeField is thread-safe and immutable.

Since:

1.0

Method Detail

get

public int get(long millis)

Description copied from class: DateTimeField

Get the value of this field from the milliseconds.

Overrides:

get in class DelegatedDateTimeField

Parameters:

millis - the milliseconds from 1970-01-01T00:00:00Z to query

the value of the field, in the units of the field

set

public long set(long millis,
                int value)

Description copied from class: DateTimeField

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.

set in class DelegatedDateTimeField

Parameters:

millis - the milliseconds from 1970-01-01T00:00:00Z to set in

value - the value to set, in the units of the field

the updated milliseconds
