## Class DefaultVectorSpatialRepresentation

- Object
- - AbstractMetadata
  - - ModifiableMetadata
    - - ISOMetadata
      - - AbstractSpatialRepresentation
        - - DefaultVectorSpatialRepresentation

- All Implemented Interfaces:
    Serializable, Cloneable, Emptiable, LenientComparable, IdentifiedObject, SpatialRepresentation, VectorSpatialRepresentation

      public class DefaultVectorSpatialRepresentation
      extends AbstractSpatialRepresentation
      implements VectorSpatialRepresentation

  Information about the vector spatial objects in the dataset.

  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

    - #### DefaultVectorSpatialRepresentation

          public DefaultVectorSpatialRepresentation()

      Constructs an initially empty vector spatial representation.

    - #### DefaultVectorSpatialRepresentation

          public DefaultVectorSpatialRepresentation(VectorSpatialRepresentation 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(VectorSpatialRepresentation)`

  - ### Method Detail

    - #### castOrCopy

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

    - #### getTopologyLevel

          public TopologyLevel getTopologyLevel()

      Returns the code which identifies the degree of complexity of the spatial relationships.
      Specified by:
        `getTopologyLevel` in interface `VectorSpatialRepresentation`
      Returns:
        the degree of complexity of the spatial relationships, or `null`.

    - #### setTopologyLevel

          public void setTopologyLevel(TopologyLevel newValue)

      Sets the code which identifies the degree of complexity of the spatial relationships.
      Parameters:
        `newValue` - the new topology level.

    - #### getGeometricObjects

          public Collection<GeometricObjects> getGeometricObjects()

      Returns information about the geometric objects used in the dataset.
      Specified by:
        `getGeometricObjects` in interface `VectorSpatialRepresentation`
      Returns:
        information about the geometric objects used in the dataset, or `null`.

    - #### setGeometricObjects

          public void setGeometricObjects(Collection<? extends GeometricObjects> newValues)

      Sets information about the geometric objects used in the dataset.
      Parameters:
        `newValues` - the new geometric objects.
