AssistantDirector で Provider 実装

UserLocaleProcessProvider

以下のインターフェースを実装して、AssistantDirector にて登録をします。 

UserLocaleProcessProviderインターフェース @Java
/**
 * The provider of user locale process for current request.

public interface UserLocaleProcessProvider {

    /**
     * Does it accept cookie locale? (prevails over session)
     * @return The determination, true or false.
     */
    boolean isAcceptCookieLocale();

     * @return The fixed instance of locale, might be cached. (NullAllowed: if null, server locale)

    Locale getFallbackLocale();
}

UserTimeZoneProcessProvider

以下のインターフェースを実装して、AssistantDirector にて登録をします。 

UserTimeZoneProcessProviderインターフェース @Java
/**
 * The provider of user time-zone process for current request.

public interface UserTimeZoneProcessProvider {

    /**
     * Does it use time-zone handling? 

     * The time-zone handling is option (not related to Struts) so you need to choose.
     * @return The determination, true or false.
     */
    boolean isUseTimeZoneHandling();

    /**
     * Does it accept cookie time-zone? (prevails over session)
     * @return The determination, true or false.
     */
    boolean isAcceptCookieTimeZone();

    TimeZone findBusinessTimeZone(ActionExecuteMeta executeMeta, RequestManager requestManager);

    /**
     * Get the requested time-zone. (for when not found in session or cookie)

     * @param requestManager The manager of request to find your time-zone. (NotNull)
     * @return The time-zone as default by your business rule. (NotNull)
     */
