DefaultCoverageDescription
DefaultImageDescription

All Implemented Interfaces:
  `Serializable`, `Emptiable`, `LenientComparable`, `IdentifiedObject`, `ContentInformation`, `CoverageDescription`, `ImageDescription`

public class DefaultImageDescription extends DefaultCoverageDescription implements ImageDescription
Information about an image's suitability for use. The following property is mandatory in a well-formed metadata according ISO 19115:
`MD_ImageDescription` `└─attributeDescription……` Description of the attribute described by the measurement value.

## 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.

Since:
  0.3

- ## Constructor Details

  - ### DefaultImageDescription

    public DefaultImageDescription()
    Constructs an initially empty image description.

  - ### DefaultImageDescription

    public DefaultImageDescription(ImageDescription 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.

    #### Note on properties validation

    This constructor does not verify the property values of the given metadata (e.g. whether a value is out of range). This is because invalid metadata exist in practice, and verifying their validity in this copy constructor is often too late. Note that this is not the only hole, as invalid metadata instances can also be obtained by unmarshalling an invalid XML document.
    Parameters:
      `object` - the metadata to copy values from, or `null` if none.
    See Also:
      - `castOrCopy(ImageDescription)`

- ## Method Details

  - ### castOrCopy

    public static DefaultImageDescription castOrCopy(ImageDescription 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 `DefaultImageDescription`, then it is returned unchanged.
    - Otherwise a new `DefaultImageDescription` 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.
