      public class AbstractElement
      extends ISOMetadata
      implements Element

  Type of test applied to the data specified by a data quality scope. The following property is mandatory in a well-formed metadata according ISO 19115:
  `DQ_Element` `└─result……………` Value obtained from applying a data quality measure.

  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:

- - ### Constructor Detail

    - #### AbstractElement

          public AbstractElement()

      Constructs an initially empty element.

    - #### AbstractElement

          public AbstractElement(Result result)

      Creates an element initialized to the given result.
      Parameters:
        `result` - the value obtained from applying a data quality measure against a specified acceptable conformance quality level.

    - #### AbstractElement

          public AbstractElement(Element 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(Element)`

  - ### Method Detail

    - #### castOrCopy

          public static AbstractElement castOrCopy(Element 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 `PositionalAccuracy`, `TemporalAccuracy`, `ThematicAccuracy`, `LogicalConsistency`, `Completeness` or `Usability`, then this method delegates to the `castOrCopy(…)` method of the corresponding SIS subclass. Note that if the given object implements more than one of the above-cited interfaces, then the `castOrCopy(…)` method to be used is unspecified.
      - Otherwise if the given object is already an instance of `AbstractElement`, then it is returned unchanged.
      - Otherwise a new `AbstractElement` 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.
