    • Method Detail

      • getLocale

        public abstract Locale getLocale()
        Returns the locale to use for (un)marshalling, or null if no locale were explicitly specified. The locale returned by this method can be used for choosing a language in an International­String.

        This locale may vary in different fragments of the same XML document. In particular children of Metadata inherit the locale specified by the Metadata​.get­Language() attribute.

        Handling of Locale​.ROOT
        Locale​.ROOT is interpreted as a request for locale-neutral strings. The meaning of "locale-neutral" is implementation specific - this is usually very close to the English locale, but not necessarily. For examples dates are formatted according ISO standard instead than the rules of the English locale.
        Handling of null locale
        A null value means that the locale is unspecified. Callers are encouraged to use the root locale as the default value, but some flexibility is allowed.
        Returns:
        the locale for the XML fragment being (un)marshalled, or null is unspecified.

        Default­International­String​.to­String(Locale)
      • getTimeZone

        public abstract TimeZone getTimeZone()
        Returns the timezone to use for (un)marshalling, or null if none was explicitly specified.
        Handling of null timezone
        A null value means that the timezone is unspecified. Callers are encouraged to use the UTC timezone as the default value, but some flexibility is allowed.
        Upcoming API change — Java time API
        Return type may be changed to Zone­Id when Apache SIS will target Java 8. This change may be applied in synchronization with GeoAPI 4.0.
        Returns:
        the timezone for the XML fragment being (un)marshalled, or null if unspecified.
      • getVersion

        public abstract Version getVersion​(String prefix)
        Returns the schema version of the XML document being (un)marshalled. The prefix argument can be any of the following values (case-sensitive):
        Supported schemas
        Prefix Standard Typical values
        gml Geographic Markup Language 3.0, 3.2
        gmd Geographic MetaData 2007, 2016
        Parameters:
        prefix - one of the above-cited prefix.
        Returns:
        the version for the given schema, or null if unknown.
