All Implemented Interfaces:

public class DefaultGeographicDescription extends AbstractGeographicExtent implements GeographicDescription
Description of the geographic area using identifiers. The following properties are mandatory in a well-formed metadata according ISO 19115:
EX_Geographic­Description   └─geographic­Identifier…… The identifier used to represent a geographic area.       └─code…………………………………… Alphanumeric value identifying an instance in the namespace.
The area is given by a geographic identifier, which may be a code in the codespace of some authority (for example an EPSG code). In addition, the geographic identifier can optionally have a natural language description.

Examples

A geographic area may be identified by the 1731 code in the EPSG codespace. The natural language description for EPSG:1731 can be “France – mainland north of 48.15°N”.

Limitations

  • Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
  • Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use XML instead.

  • Constructor Details

    • DefaultGeographicDescription

      public DefaultGeographicDescription()
      Constructs an initially empty geographic description.

    • DefaultGeographicDescription

      public DefaultGeographicDescription(Citation authority, String code)
      Creates an inclusive geographic description initialized to the given identifier. This constructor sets the inclusion property to true.

      Usage note

      If the description is a sentence like “Netherlands offshore”, it may not be suitable for the code argument. Callers may consider using the identifier description as an alternative and keep the code for a more compact string (often a primary key).

      Example

      new Default­Geographic­Description(Citations​.EPSG, "1731") can stand for “France – mainland north of 48.15°N”.
      Parameters:
      authority - the authority of the identifier code, or null if none.
      code - the identifier code used to represent a geographic area, or null if none.

    • DefaultGeographicDescription

      public DefaultGeographicDescription(CharSequence description)
      Creates an inclusive geographic description initialized to the given natural language description. This constructor sets the inclusion property to true and the identifier code to one of the following choices:
      Parameters:
      description - the natural language description of the meaning of the code value, or null if none.

    • DefaultGeographicDescription

      public DefaultGeographicDescription(GeographicDescription object)
      Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, because the other metadata contained in the given object are not recursively copied.
      Parameters:
      object - the metadata to copy values from, or null if none.

    • castOrCopy

      public static DefaultGeographicDescription castOrCopy(GeographicDescription object)
      Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
      • If the given object is null, then this method returns null.
      • Otherwise if the given object is already an instance of Default­Geographic­Description, then it is returned unchanged.
      • Otherwise a new Default­Geographic­Description instance is created using the copy constructor and returned. Note that this is a shallow copy operation, because the other metadata contained in the given object are not recursively copied.
      Parameters:
      object - the object to get as a SIS implementation, or null if none.
      Returns:
      a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.

    • getGeographicIdentifier

      public Identifier getGeographicIdentifier()
      Returns the identifier used to represent a geographic area.

      Example

      An identifier with the following properties:
      • the "EPSG" code space,
      • the "1731" code, and
      • the “France – mainland north of 48.15°N” description.
      Specified by:
      get­Geographic­Identifier in interface Geographic­Description
      Returns:
      the identifier used to represent a geographic area, or null.

    • setGeographicIdentifier

      public void setGeographicIdentifier(Identifier newValue)
      Sets the identifier used to represent a geographic area.
      Parameters:
      new­Value - the new geographic identifier.
