Copy values from given bounding box.
param  bbox not null
public void set (BBox bbox)

public void setRange (int ordinate, double min, double max)


Grow this bounding to contain the given one.
param  bbox
public void expand (BBox bbox)


Grow this bounding to contain the given point.
param  point
public void expand (Tuple point)


Grow this bounding to contain the given point.
param  point
public void expand (double[] point)


Grow this bounding to contain all tuples in buffer.
param  buffer
public void expand (TupleBuffer buffer)


Grow this bounding to contain the given point.
param  point
public void expand (float[] point)

public void expand (double px)

public void expand (double px, double py)

public void expand (double px, double py, double pz)

public void expand (double px, double py, double pz, double pw)


Expand the bbox in all directions by given amount.
public void grow (double amount)


return  true if lower corner equals upper corner.
public boolean isEmpty ()


Set all values to zero
public void setToZero ()


Set all values to NaN.
public void setToNaN ()


Check that all values are not NaN or Infinites.
return  true if valid
public boolean isValid ()


Reorder values, ensure min/max values are in
lower/upper corners.
public void reorder ()

Test intersection with an Extent.
The extent is interpreted as a BBox starting at coordinate zero on each dimension.
TODO : make extent a geometry ?
param  extent
param  includeBorder
return
public boolean intersects (Extent extent, boolean includeBorder)

public boolean contains (BBox bbox)


Intersect this bbox with given one, store the result in this bbox.
This method does not perform any verification.
param  bbox
return
public void localIntersect (BBox bbox)
