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

Direct Known Subclasses:
  `DefaultLegalConstraints`, `DefaultSecurityConstraints`

public class DefaultConstraints extends ISOMetadata implements Constraints
Restrictions on the access and use of a resource or metadata.

## 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

  - ### DefaultConstraints

    public DefaultConstraints()
    Constructs an initially empty constraints.

  - ### DefaultConstraints

    public DefaultConstraints(CharSequence useLimitation)
    Constructs a new constraints with the given use limitation.
    Parameters:
      `useLimitation` - the use limitation, or `null` if none.

  - ### DefaultConstraints

    public DefaultConstraints(Constraints 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(Constraints)`

- ## Method Details

  - ### castOrCopy

    public static DefaultConstraints castOrCopy(Constraints 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 `LegalConstraints` or `SecurityConstraints`, 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 `DefaultConstraints`, then it is returned unchanged.
    - Otherwise a new `DefaultConstraints` 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.

  - ### getUseLimitations

    public Collection<InternationalString> getUseLimitations()
    Returns the limitation affecting the fitness for use of the resource. Example: not to be used for navigation.
    Specified by:
      `getUseLimitations` in interface `Constraints`
    Returns:
      limitation affecting the fitness for use of the resource.

  - ### setUseLimitations

    public void setUseLimitations(Collection<? extends InternationalString> newValues)
