        public Envelope2DArchived​(Bounds envelope)
        Constructs two-dimensional envelope defined by an other Bounds.
        Parameters:
        envelope - The envelope to copy.

      • Envelope2DArchived

        public Envelope2DArchived​(CoordinateReferenceSystem crs,
                          Rectangle2D rect)
        Constructs two-dimensional envelope defined by an other Rectangle2D.

      • Envelope2DArchived

        public Envelope2DArchived​(CoordinateReferenceSystem crs,
                          double x,
                          double y,
                          double width,
                          double height)
        Constructs two-dimensional envelope defined by the specified coordinates. Despite their name, the (x,y) coordinates don't need to be oriented toward (East, North). Those parameter names simply match the x and y fields. The actual axis orientations are determined by the specified CRS. See the class javadoc for details.
        Parameters:
        crs - The coordinate reference system, or null.
        x - The x minimal value.
        y - The y minimal value.
        width - The envelope width.
        height - The envelope height.

      • Envelope2DArchived

        public Envelope2DArchived​(Position2D minDP,
                          Position2D maxDP)
                   throws MismatchedReferenceSystemException
        Constructs two-dimensional envelope defined by the specified coordinates. Despite their name, the (x,y) coordinates don't need to be oriented toward (East, North). Those parameter names simply match the x and y fields. The actual axis orientations are determined by the specified CRS. See the class javadoc for details.

        The minDP and maxDP arguments usually contains the minimal and maximal ordinate values respectively, but this is not mandatory. The ordinates will be rearanged as needed.

        Parameters:
        minDP - The fist position.
        maxDP - The second position.
        Throws:
        MismatchedReferenceSystemException - if the two positions don't use the same CRS.
        Since:

      • boundsEquals

        public boolean boundsEquals​(Bounds that,
                            int xDim,

      • toString

        public String toString()

        2.4

      • setBounds

        Parameters:
        bounds - The new bounds.

      • include

        public void include​(BoundingBox bounds)

        Description copied from interface: BoundingBox
        Includes the provided coordinates, expanding as necessary. Note that there is no guarantee that the (x, x) values are oriented toward (East, North), since it depends on the envelope CRS.
        Specified by:
        include in interface BoundingBox
        Parameters:
        x - The first ordinate value.
        y - The second ordinate value.

      • intersects

        public boolean intersects​(BoundingBox bounds)
        Returns true if the interior of this bounds intersects the interior of the provided bounds.

        Note this method conflicts with RectangularShape.intersects(Rectangle2D) so you may need to call it via envelope2d.intersects( (Envelope2DArchived) bounds ) in order to correctly check that the coordinate reference systems match.

        Specified by:
        intersects in interface BoundingBox
        Parameters:
        bounds - The bounds to test for intersection.
        Returns:
        true if the two bounds intersect.

      • contains

        public boolean contains​(BoundingBox bounds)
        Description copied from interface: BoundingBox
        Returns true if the provided bounds are contained by this bounding box.
        Specified by:
        contains in interface BoundingBox

        true if the given bounds is inside this bounds.

      • contains

        public boolean contains​(Position location)
        Description copied from interface: BoundingBox

        Returns:
        true if the given position is inside this bounds.

      • toBounds

        public BoundingBox toBounds​(CoordinateReferenceSystem targetCRS)
                     throws TransformException
        Description copied from interface: BoundingBox
        Transforms this box to the specified CRS and returns a new bounding box for the transformed shape. This method provides a convenient (while not always efficient) way to get minimum and maximum ordinate values toward some specific axis directions, typically East and North.

        Example: if box is a bounding box using a geographic CRS with WGS84 datum, then one can write: 

         GeographicCRS targetCRS   = crsAuthorityFactory.createGeographicCRS("EPSG:4326");
 BoundingBox   targetBox   = box.toBounds(targetCRS);
 double        minEasting  = targetBox.getMinY();
 double        minNorthing = targetBox.getMinX();
        Be aware that "EPSG:4326" has (latitude, longitude) axis order, thus the inversion of X and Y in the above code.

        Sophesticated applications will typically provide more efficient way to perform similar transformations in their context. For example Canvas store precomputed objective to display transforms.

        Specified by:
        toBounds in interface BoundingBox
        Parameters:
        targetCRS - The target CRS for the bounding box to be returned.
        Returns:
        A new bounding box wich includes the shape of this box transformed to the specified target CRS.
        Throws:
        TransformException - if no transformation path has been found from this box CRS to the specified target CRS, or if the transformation failed for an other reason.
