| Envelope2D | | public class Envelope2D extends Rectangle2D.Double implements Envelope,Cloneable(Code) | | A two-dimensional envelope on top of
Rectangle2D . This implementation is provided for
interoperability between Java2D and GeoAPI.
Note: This class inherits
and
fields. But
despite their names, they don't need to be oriented toward
and
respectively. The (x,y) axis
can have any orientation and should be understood as "ordinate 0" and "ordinate 1" values
instead. This is not specific to this implementation; in Java2D too, the visual axis orientation
depend on the

| Envelope2D | | public Envelope2D(Envelope envelope)(Code) | | Constructs two-dimensional envelope defined by an other
Envelope .
|
| Envelope2D | | public Envelope2D(CoordinateReferenceSystem crs, Rectangle2D rect)(Code) | | Constructs two-dimensional envelope defined by an other
Rectangle2D .
|
| Envelope2D | | public Envelope2D(CoordinateReferenceSystem crs, double x, double y, double width, double height)(Code) | | Constructs two-dimensional envelope defined by the specified coordinates. Despite
their name, the (x,y) coordinates don't need to be oriented
toward (
,
).
Those parameter names simply match the
and
fields.
The actual axis orientations are determined by the specified CRS.
See the
for details.

| Envelope2D | | public Envelope2D(DirectPosition2D minDP, DirectPosition2D maxDP) throws MismatchedReferenceSystemException(Code) | | Constructs two-dimensional envelope defined by the specified coordinates. Despite
their name, the (x,y) coordinates don't need to be oriented
toward (
,
).
Those parameter names simply match the
and
fields.
The actual axis orientations are determined by the specified CRS.
See the
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.
Parameters:
maxDP - The second position.
throws:
MismatchedReferenceSystemException - if the two positions don't use the same CRS.

| boundsEquals | | public boolean boundsEquals(Envelope that, int xDim, int yDim, double eps)(Code) | | Returns
true if
this envelope bounds is equals to
that envelope
bounds in two specified dimensions. The coordinate reference system is not compared, since
it doesn't need to have the same number of dimensions.
Parameters:
that - The envelope to compare to.
Parameters:
xDim - The dimension of that envelope to compare to the x dimensionof this envelope.
Parameters:
yDim - The dimension of that envelope to compare to the y dimensionof this envelope.
Parameters:
eps - A small tolerance number for floating point number comparaisons. This value willbe scaled according this envelope and. true if the envelope bounds are the same (up to the specified tolerancelevel) in the specified dimensions, or false otherwise. |
| equals | | public boolean equals(Object object)(Code) | | Compares the specified object with this envelope for equality.
|
| getCenter | | final public double getCenter(int dimension)(Code) | | Returns the center ordinate along the specified dimension.

| getDimension | | final public int getDimension()(Code) | | Returns the number of dimensions.
|
| getLength | | final public double getLength(int dimension)(Code) | | Returns the envelope length along the specified dimension.
This length is equals to the maximum ordinate minus the
minimal ordinate.
|
| getLowerCorner | | public DirectPosition getLowerCorner()(Code) | | A coordinate position consisting of all the minimal ordinates for each
dimension for all points within the
Envelope .

| getMaximum | | final public double getMaximum(int dimension)(Code) | | Returns the maximal ordinate along the specified dimension.
|
| getMinimum | | final public double getMinimum(int dimension)(Code) | | Returns the minimal ordinate along the specified dimension.
|
| getUpperCorner | | public DirectPosition getUpperCorner()(Code) | | A coordinate position consisting of all the maximal ordinates for each
dimension for all points within the
Envelope .
The upper corner.DirectPosition2D |
| hashCode | | public int hashCode()(Code) | | Returns a hash value for this envelope. This value need not remain consistent between
different implementations of the same class.
|
| setCoordinateReferenceSystem | | public void setCoordinateReferenceSystem(CoordinateReferenceSystem crs)(Code) | | Set the coordinate reference system in which the coordinate are given.
Parameters:
crs - The new coordinate reference system, or null . |
| toString | | public String toString()(Code) | | Returns a string representation of this envelope. The default implementation is okay
for occasional formatting (for example for debugging purpose). But if there is a lot
of envelopes to format, users will get more control by using their own instance of
org.geotools.measure.CoordinateFormat .
