# Class DefaultCoverageDescription

Object
AbstractMetadata
ModifiableMetadata
ISOMetadata
AbstractContentInformation
DefaultCoverageDescription

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

Direct Known Subclasses:
  `DefaultImageDescription`

public class DefaultCoverageDescription extends AbstractContentInformation implements CoverageDescription
Information about the content of a grid data cell. The following property is mandatory in a well-formed metadata according ISO 19115:
`MD_CoverageDescription` `└─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

  - ### DefaultCoverageDescription

    public DefaultCoverageDescription()
    Constructs an empty coverage description.

  - ### DefaultCoverageDescription

    public DefaultCoverageDescription(CoverageDescription 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.
    See Also:
      - `castOrCopy(CoverageDescription)`

- ## Method Details

  - ### castOrCopy

    public static DefaultCoverageDescription castOrCopy(CoverageDescription 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 an instance of `ImageDescription`, then this method delegates to the `castOrCopy(…)` method of the corresponding SIS subclass.
    - Otherwise if the given object is already an instance of `DefaultCoverageDescription`, then it is returned unchanged.
    - Otherwise a new `DefaultCoverageDescription` 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.

  - ### getAttributeDescription

    public RecordType getAttributeDescription()
    Returns the description of the attribute described by the measurement value.
    Specified by:
      `getAttributeDescription` in interface `CoverageDescription`
    Returns:
      description of the attribute.

  - ### setAttributeDescription

    public void setAttributeDescription(RecordType newValue)
    Sets the description of the attribute described by the measurement value.
    Parameters:
      `newValue` - the new attribute description.

  - ### getProcessingLevelCode

    @UML(identifier="processingLevelCode", obligation=OPTIONAL, specification=ISO_19115) public Identifier getProcessingLevelCode()
    Returns an identifier for the level of processing that has been applied to the resource, or `null` if none. For image descriptions, this is the image distributor's code that identifies the level of radiometric and geometric processing that has been applied.
    Returns:
      identifier for the level of processing that has been applied to the resource, or `null` if none.
    Since:
      0.5

  - ### setProcessingLevelCode

    public void setProcessingLevelCode(Identifier newValue)
    Sets the identifier for the level of processing that has been applied to the resource.
    Parameters:
      `newValue` - the new identifier for the level of processing.
    Since:
      0.5

  - ### getAttributeGroups

    @UML(identifier="attributeGroup", obligation=OPTIONAL, specification=ISO_19115) public Collection<DefaultAttributeGroup> getAttributeGroups()
    Returns information on attribute groups of the resource.
