# Class DefaultCitation

DefaultCitation

All Implemented Interfaces:
  `Serializable`, `Emptiable`, `LenientComparable`, `IdentifiedObject`, `Citation`

@TitleProperty(name="title") public class DefaultCitation extends ISOMetadata implements Citation
Standardized resource reference. The following properties are mandatory in a well-formed metadata according ISO 19115:
`CI_Citation` `├─title………………………` Name by which the cited resource is known. `└─date…………………………` Reference date for the cited resource.

## Unified identifiers view

The ISO 19115 model provides specific attributes for the ISBN and ISSN codes. However the SIS library handles those codes like any other identifiers. Consequently the ISBN and ISSN codes are included in the collection returned by `getIdentifiers()`, except at XML marshalling time (for ISO 19115-3 compliance).

## 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.

  0.3

- ## Constructor Details

  - ### DefaultCitation

    public DefaultCitation()
    Constructs an initially empty citation.

  - ### DefaultCitation

    public DefaultCitation(CharSequence title)
    Constructs a citation with the specified title.
    Parameters:
      `title` - the title as a `String` or an `InternationalString` object, or `null` if none.

  - ### DefaultCitation

    public DefaultCitation(Citation object)
    Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.
    Parameters:
      `object` - the metadata to copy values from, or `null` if none.
    See Also:
      - `castOrCopy(Citation)`

- ## Method Details

  - ### castOrCopy

    public static DefaultCitation castOrCopy(Citation 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 `DefaultCitation`, then it is returned unchanged.
    - Otherwise a new `DefaultCitation` instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since 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.
