@UML(identifier="IO_IdentifiedObject",
     specification=ISO_19111)
public interface IdentifiedObject

Supplementary identification and remarks information for a CRS or CRS-related object. When CRSAuthorityFactory is used to create an object, the authority and authority code values shall be set to the authority name of the factory object, and the authority code supplied by the client, respectively. The other values may or may not be set. If the authority is EPSG, the implementer may consider using the corresponding metadata values in the EPSG tables.

Since:

2.0

Departure from OGC/ISO abstract specification:

Departure for harmonization between different specifications

ISO 19111 defines an IdentifiedObjectBase interface. The later is omitted in GeoAPI because the split between IdentifiedObject and IdentifiedObjectBase in the ISO/OGC specification was a workaround for introducing IdentifiedObject in ISO 19111 without changing the ReferenceSystem definition in ISO 19115 but GeoAPI does not need this workaround.

Field Details

NAME_KEY

static final String NAME_KEY

Key for the "name" property to be given to the object factory createFoo(…) methods. This is used for setting the value to be returned by getName().

• Constant Field Values

ALIAS_KEY

static final String ALIAS_KEY

Key for the "alias" property to be given to the object factory createFoo(…) methods. This is used for setting the value to be returned by getAlias().

See Also:

• getAlias()
• Constant Field Values

IDENTIFIERS_KEY

static final String IDENTIFIERS_KEY

Key for the "identifiers" property to be given to the object factory createFoo(…) methods. This is used for setting the value to be returned by getIdentifiers().

See Also:

• getIdentifiers()
• Constant Field Values

REMARKS_KEY

static final String REMARKS_KEY

Key for the "remarks" property to be given to the object factory createFoo(…) methods. This is used for setting the value to be returned by getRemarks().

See Also:

• getRemarks()
• Constant Field Values

Method Details

getName

@UML(identifier="name",
     obligation=MANDATORY,
     specification=ISO_19111)
ReferenceIdentifier getName()

The primary name by which this object is identified.

Returns:

The primary name.

getAlias

@UML(identifier="alias",
     obligation=OPTIONAL,
     specification=ISO_19111)
Collection<GenericName> getAlias()

An alternative name by which this object is identified.

Returns:

The aliases, or an empty collection if there is none.

getIdentifiers

@UML(identifier="identifier",
     obligation=OPTIONAL,
     specification=ISO_19111)
Set<ReferenceIdentifier> getIdentifiers()

An identifier which references elsewhere the object's defining information. Alternatively an identifier by which this object can be referenced.

Returns:

This object identifiers, or an empty set if there is none.

getRemarks

@UML(identifier="remarks",
     obligation=OPTIONAL,
     specification=ISO_19111)
InternationalString getRemarks()

Comments on or information about this object, including data source information.

Returns:

The remarks, or null if none.

toWKT

String toWKT()
      throws UnsupportedOperationException

Returns a Well Known Text (WKT) for this object. This operation may fails if an object is too complex for the WKT format capability (for example an engineering CRS with different unit for each axis).

Returns:

The Well Know Text for this object.

Throws:

UnsupportedOperationException - If this object cannot be formatted as WKT.

Departure from OGC/ISO abstract specification:

Addition of element not in the ISO/OGC specification

This method is not part of the OGC specification. It has been added in order to provide the converse of the CRSFactory.createFromWKT(String) method, which is defined in OGC 01-009.
