Class DefaultBoundingPolygon

AbstractGeographicExtent
DefaultBoundingPolygon
All Implemented Interfaces:
Serializable, Emptiable, Lenient­Comparable, Identified­Object, Bounding­Polygon, Geographic­Extent
public class DefaultBoundingPolygon extends AbstractGeographicExtent implements BoundingPolygon
Boundary enclosing the dataset, expressed as the closed set of (x,y) coordinates of the polygon. The last point replicates first point.

The following property is mandatory in a well-formed metadata according ISO 19115:

EX_Bounding­Polygon   └─polygon………………… The sets of points defining the bounding polygon.

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.

  • Constructor Details

    • DefaultBoundingPolygon

      public DefaultBoundingPolygon()
      Constructs an initially empty bounding polygon.

    • DefaultBoundingPolygon

      public DefaultBoundingPolygon(Geometry polygon)
      Creates a bounding polygon initialized to the specified polygon.
      Parameters:
      polygon - the sets of points defining the bounding polygon.

    • DefaultBoundingPolygon

      public DefaultBoundingPolygon(BoundingPolygon 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.

  • Method Details

    • castOrCopy

      public static DefaultBoundingPolygon castOrCopy(BoundingPolygon 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 Default­Bounding­Polygon, then it is returned unchanged.
      • Otherwise a new Default­Bounding­Polygon 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.

    • getPolygons

      public Collection<Geometry> getPolygons()
      Returns the sets of points defining the bounding polygon or other geometry.
      Specified by:
      get­Polygons in interface Bounding­Polygon
      Returns:
      the sets of points defining the resource boundary.

    • setPolygons

      public void setPolygons(Collection<? extends Geometry> newValues)
      Sets the sets of points defining the resource boundary.
      Parameters:
      new­Values - the new boundaries.
