PUSH_FORWARD

public static final GapResolver PUSH_FORWARD

Default strategy which moves an invalid local time by the length of the gap into the future.

Example for the switch to summer time in the timezone "Europe/Berlin": 2015-03-29T02:30+01:00 => 2015-03-29T03:30+02:00

NEXT_VALID_TIME

public static final GapResolver NEXT_VALID_TIME

Alternative strategy which moves an invalid local time forward to the first valid time after transition.

Example for the switch to summer time in the timezone "Europe/Berlin": 2015-03-29T02:30+01:00 => 2015-03-29T03:00+02:00

ABORT

public static final GapResolver ABORT

Strict strategy which rejects an invalid local time by throwing an exception.

Method Details

values

public static GapResolver[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static GapResolver valueOf(String name)
