## com.bbn.openmap.layer.shape
Class ESRIBoundingBox

    java.lang.Object
      com.bbn.openmap.layer.shape.ESRIBoundingBox

public class ESRIBoundingBox
extends java.lang.Object

A bounding box is a rectangle that fully encloses some number of shapes. The rectangle is represented as four doubles, xmin ymin, xmax, and ymax.

## To Do

- Make addPoint take two doubles to avoid unnecessarily consing ESRIPoints to add to the box.

Field Detail

### min

    public ESRIPoint min

  The minimum point.

### max

    public ESRIPoint max

  The maximum point.

Constructor Detail

### ESRIBoundingBox

    public ESRIBoundingBox()

  Initialize a null bounding box. All coordinates are set to zero.

### ESRIBoundingBox

    public ESRIBoundingBox(ESRIPoint point)

  Initialize a bounding box from a point. The bounding box is initialized to encompass the given point.

Parameters:
  `point` - the point to enclose

### ESRIBoundingBox

    public ESRIBoundingBox(double x,
                           double y)

  Initialize a bounding box from two doubles representing a point. The bounding box is initialized to encompass the given location.

Parameters:
  `x` - the x coordinate
  `y` - the y coordinate

### ESRIBoundingBox

    public ESRIBoundingBox(ESRIPoint _min,
                           ESRIPoint _max)

  Initialize a bounding box to encompass a minimum and maximum point. The bounding box is initialized to fully encompass both points.

Parameters:
  `_min` - a point to enclose
  `_max` - another point to enclose

Method Detail

### addBounds

    public void addBounds(ESRIBoundingBox bb)

  Increase the extents of this bounding box to enclose the given bounding box.

  Parameters:
    `bb` - a bounding box to be enclosed

### addPoints

    public void addPoints(ESRIPoint[] points)

  Increase the extents of this bounding box to enclose all of the given points.

  Parameters:
    `points` - a set of points to enclose

### addPoint

    public void addPoint(ESRIPoint point)

  Increase the extents of this bounding box to enclose the given point.

  Parameters:
    `point` - a point to enclose

### addPoint

    public void addPoint(double x,
                         double y)

### equals

    public boolean equals(java.lang.Object obj)

  Determines equality with another bounding box

  Parameters:
    `obj` - a candidate object
  Returns:
    `true` if `obj` is of type `ESRIBoundingBox` and the extents of that bounding box match this box's extents. `false` otherwise.
