    @UML(identifier="IdentifiedObject",

    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 should 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:
  GeoAPI 2.0
Version:
  Abstract specification 2.0

Field Summary
`static String` `ALIAS_KEY` Key for the `"alias"` property to be given to the object factory `createFoo(…)` methods.
`static String` `IDENTIFIERS_KEY` Key for the `"identifiers"` property to be given to the object factory `createFoo(…)` methods.
`static String` `NAME_KEY` Key for the `"name"` property to be given to the object factory `createFoo(…)` methods.
`static String` `REMARKS_KEY` Key for the `"remarks"` property to be given to the object factory `createFoo(…)` methods.

Method Summary
`Collection<GenericName>` `getAlias()` An alternative name by which this object is identified.
`Set<ReferenceIdentifier>` `getIdentifiers()` An identifier which references elsewhere the object's defining information.
`ReferenceIdentifier` `getName()` The primary name by which this object is identified.
`InternationalString` `getRemarks()` Comments on or information about this object, including data source information.
`String` `toWKT()` Returns a Well Known Text (WKT) for this object.

Field Detail

### 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()`.

  See Also:
    `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 Detail

### getName

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

  The primary name by which this object is identified.

### 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.

### toWKT

    @Extension
    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 can't be formatted as WKT.
