## Class DefaultConstraints

- Object
- - AbstractMetadata
  - - ModifiableMetadata
    - - ISOMetadata
      - - DefaultConstraints

- All Implemented Interfaces:
    Serializable, Cloneable, 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 Detail

    - #### 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, 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(Constraints)`

  - ### Method Detail

    - #### 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, 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.
