# Class DefaultQuantitativeResult

Object
AbstractMetadata
ModifiableMetadata
ISOMetadata
AbstractResult
DefaultQuantitativeResult

All Implemented Interfaces:
  `Serializable`, `Emptiable`, `LenientComparable`, `IdentifiedObject`, `QuantitativeResult`, `Result`

public class DefaultQuantitativeResult extends AbstractResult implements QuantitativeResult
Information about the value (or set of values) obtained from applying a data quality measure. See the `QuantitativeResult` GeoAPI interface for more details. The following properties are mandatory in a well-formed metadata according ISO 19157:
`DQ_QuantitativeResult` `├─valueUnit……………………` Value unit for reporting a data quality result. `└─value………………………………` Quantitative value or values, content determined by the evaluation procedure used.

## 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

  - ### DefaultQuantitativeResult

    public DefaultQuantitativeResult()
    Constructs an initially empty quantitative result.

  - ### DefaultQuantitativeResult

    public DefaultQuantitativeResult(QuantitativeResult 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(QuantitativeResult)`

- ## Method Details

  - ### castOrCopy

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

  - ### getValues

    public List<Record> getValues()
    Returns the quantitative value or values, content determined by the evaluation procedure used.
    Specified by:
      `getValues` in interface `QuantitativeResult`
    Returns:
      Quantitative value or values.

  - ### setValues

    public void setValues(List<? extends Record> newValues)
    Sets the quantitative value or values, content determined by the evaluation procedure used.
    Parameters:
      `newValues` - the new values.

  - ### getValueType

    public RecordType getValueType()
    Returns the value type for reporting a data quality result.

    #### Default value

    If no type has been set but all values are of the same type, then this method defaults to that type. Otherwise this method returns `null`.
    Specified by:
      `getValueType` in interface `QuantitativeResult`
    Returns:
      value type for reporting a data quality result, or `null`.

  - ### setValueType

    public void setValueType(RecordType newValue)
    Sets the value type for reporting a data quality result. A `null` value restores the default value documented in `getValueType()`.
    Parameters:
      `newValue` - the new value type.

  - ### getValueUnit

    public Unit<?> getValueUnit()
    Returns the value unit for reporting a data quality result.
    Specified by:
      `getValueUnit` in interface `QuantitativeResult`
    Returns:
      value unit for reporting a data quality result, or `null`.

  - ### setValueUnit

    public void setValueUnit(Unit<?> newValue)
    Sets the value unit for reporting a data quality result.
    Parameters:
      `newValue` - the new value unit.

  - ### getErrorStatistic

    @Deprecated(since="1.3") public InternationalString getErrorStatistic()
    Deprecated.
    Removed from ISO_19157:2013.
    Returns the statistical method used to determine the value.
    Specified by:
      `getErrorStatistic` in interface `QuantitativeResult`
    Returns:
      statistical method used to determine the value, or `null`.

  - ### setErrorStatistic

    @Deprecated(since="1.3") public void setErrorStatistic(InternationalString newValue)
    Deprecated.
    Removed from ISO_19157:2013.
    Sets the statistical method used to determine the value, or `null` if none.
    Parameters:
      `newValue` - the new error statistic.

  - ### getStandard

    public MetadataStandard getStandard()
    Returns the metadata standard, which is ISO 19157.
    Overrides:
      `getStandard` in class `ISOMetadata`
    Returns:
      the metadata standard, which is ISO 19157.
