coordinateSystem
protected final org.opengis.referencing.cs.CoordinateSystem coordinateSystem
- The coordinate system.
AbstractCRS
public AbstractCRS(org.opengis.referencing.crs.CoordinateReferenceSystem crs)
- Constructs a new coordinate reference system with the same values than the specified one.
This copy constructor provides a way to wrap an arbitrary implementation into a
Geotools one or a user-defined one (as a subclass), usually in order to leverage
some implementation-specific API. This constructor performs a shallow copy,
i.e. the properties are not cloned.
- Parameters:
crs
- The coordinate reference system to copy.- Since:
- 2.2
AbstractCRS
public AbstractCRS(java.util.Map<java.lang.String,?> properties,
org.opengis.referencing.cs.CoordinateSystem cs)
- Constructs a coordinate reference system from a set of properties. The properties are given
unchanged to the super-class
constructor.
- Parameters:
properties
- Set of properties. Should contains at least "name"
.cs
- The coordinate system.
getCoordinateSystem
public org.opengis.referencing.cs.CoordinateSystem getCoordinateSystem()
- Returns the coordinate system.
- Specified by:
getCoordinateSystem
in interface org.opengis.referencing.crs.CoordinateReferenceSystem
distance
public Measure distance(double[] coord1,
double[] coord2)
throws java.lang.UnsupportedOperationException,
org.opengis.geometry.MismatchedDimensionException
- Computes the distance between two points. This convenience method delegates the work to
the underlyling coordinate system, if possible.
- Parameters:
coord1
- Coordinates of the first point.coord2
- Coordinates of the second point.
- Returns:
- The distance between
coord1
and coord2
.
- Throws:
java.lang.UnsupportedOperationException
- if this coordinate reference system can't compute
distances.
org.opengis.geometry.MismatchedDimensionException
- if a coordinate doesn't have the expected dimension.
equals
public boolean equals(AbstractIdentifiedObject object,
boolean compareMetadata)
- Compare this coordinate reference system with the specified object for equality.
If
compareMetadata
is true
, then all available properties are
compared including valid area and scope.
- Overrides:
equals
in class AbstractReferenceSystem
- Parameters:
object
- The object to compare to this
.compareMetadata
- true
for performing a strict comparaison, or
false
for comparing only properties relevant to transformations.
- Returns:
true
if both objects are equal.
hashCode
public int hashCode()
- Returns a hash value for this CRS. Name,
identifiers and remarks
are not taken in account. In other words, two CRS objects will return the same
hash value if they are equal in the sense of
equals
(AbstractIdentifiedObject,
false)
.
- Overrides:
hashCode
in class AbstractIdentifiedObject
- Returns:
- The hash code value. This value doesn't need to be the same
in past or future versions of this class.
formatWKT
protected java.lang.String formatWKT(Formatter formatter)
- Formats the inner part of a
Well
Known Text (WKT) element. The default implementation writes the following
elements:
- Overrides:
formatWKT
in class Formattable
- Parameters:
formatter
- The formatter to use.
- Returns:
- The name of the WKT element type (e.g.
"GEOGCS"
). - See Also:
Formattable.toWKT()
,
Formattable.toString()
