Examples of org.geotools.referencing.NamedIdentifier

org.geotools.referencing.NamedIdentifier
An identification of a CRS object. The main interface implemented by this class is {@link ReferenceIdentifier}. However, this class also implements {@link GenericName}in order to make it possible to reuse the same identifiers in the list of {@linkplain AbstractIdentifiedObject#getAlias aliases}. Casting an alias's {@linkplain GenericName generic name} to an {@linkplain ReferenceIdentifier identifier}gives access to more informations, like the URL of the authority.
The {@linkplain GenericName generic name} will be infered from{@linkplain ReferenceIdentifier identifier} attributes. More specifically, a{@linkplain ScopedName scoped name} will be constructed using the shortest authority's{@linkplain Citation#getAlternateTitles alternate titles} (or the{@linkplain Citation#getTitle main title} if there is no alternate titles) as the{@linkplain ScopedName#getScope scope}, and the {@linkplain #getCode code} as the{@linkplain ScopedName#asLocalName head}. This heuristic rule seems raisonable since, according ISO 19115, the {@linkplain Citation#getAlternateTitles alternatetitles} often contains abreviation (for example "DCW" as an alternative title for"Digital Chart of the World"). @since 2.1 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD)
