Package net.time4j.format

Interface WeekdataProvider

public interface WeekdataProvider

This SPI-interface enables the access to localized week rules and is instantiated via a ServiceLoader-mechanism.

If there is no external WeekdataProvider then Time4J will use an internal implementation which is based on all informations contained in the JDK and also the CLDR-data of unicode consortium. Especially the data which define a weekend will be preferably read from the resource file "data/weekend.data".

Note: All implementations must have a public no-arg constructor.
