Interface ZonedDateTimeStrategy

All Known Implementing Classes:

EnvironmentZonedDateTimeStrategy, KeepingZonedDateTimeStrategy, StaticZonedDateTimeStrategy, SystemZonedDateTimeStrategy

public interface ZonedDateTimeStrategy

Can transform a given ZoneId into another, based on rules set by the implementing classes.

Within freemarker-java-8 this is used only within the ZonedDateTimeAdapter to figure out what ZoneId to use when formatting a ZonedDateTime into a String.

Example

     zoned_date_time_object.format('yyyy-MM-dd Z')
 

In the about example the ZonedDateTime object will by default be formatted with the same timezone as found inside the object. This was not the case in earlier versions of the library, where we would use the system timezone. But this might not be the wanted default behaviour for everybody. By introducing this interface it is possible to control what timezone to use as default when formatting a ZonedDateTime and no timezone is specified in the format method.
