Field Detail

ordinate

public double ordinate
The ordinate value.

Constructor Detail

DirectPosition1D

public DirectPosition1D()
Constructs a position initialized to (0) with a null coordinate reference system.


DirectPosition1D

public DirectPosition1D(org.opengis.referencing.crs.CoordinateReferenceSystem crs)
Constructs a position with the specified coordinate reference system.

Parameters:
crs - The coordinate reference system.

DirectPosition1D

public DirectPosition1D(double ordinate)
Constructs a 1D position from the specified ordinate.

Parameters:
ordinate - The ordinate value.

DirectPosition1D

public DirectPosition1D(org.opengis.geometry.DirectPosition point)
Constructs a position initialized to the same values than the specified point.

Parameters:
point - The position to copy.
Method Detail

getCoordinateReferenceSystem

public final org.opengis.referencing.crs.CoordinateReferenceSystem getCoordinateReferenceSystem()
Returns the coordinate reference system in which the coordinate is given. May be null if this particular DirectPosition is included in a larger object with such a reference to a coordinate reference system.

Specified by:
getCoordinateReferenceSystem in interface org.opengis.geometry.DirectPosition
Returns:
The coordinate reference system, or null.

setCoordinateReferenceSystem

public void setCoordinateReferenceSystem(org.opengis.referencing.crs.CoordinateReferenceSystem crs)
Set the coordinate reference system in which the coordinate is given.

Parameters:
crs - The new coordinate reference system, or null.

getDimension

public final int getDimension()
The length of coordinate sequence (the number of entries). This is always 1 for DirectPosition1D objects.

Specified by:
getDimension in interface org.opengis.geometry.DirectPosition
Returns:
The dimensionality of this position.

getCoordinate

public double[] getCoordinate()
Returns a sequence of numbers that hold the coordinate of this position in its reference system.

Specified by:
getCoordinate in interface org.opengis.geometry.DirectPosition
Overrides:
getCoordinate in class AbstractDirectPosition
Returns:
The coordinates.

getOrdinate

public final double getOrdinate(int dimension)
                         throws java.lang.IndexOutOfBoundsException
Returns the ordinate at the specified dimension.

Specified by:
getOrdinate in interface org.opengis.geometry.DirectPosition
Parameters:
dimension - The dimension, which must be 0.
Returns:
The ordinate.
Throws:
java.lang.IndexOutOfBoundsException - if the specified dimension is out of bounds.

setOrdinate

public final void setOrdinate(int dimension,
                              double value)
                       throws java.lang.IndexOutOfBoundsException
Sets the ordinate value along the specified dimension.

Specified by:
setOrdinate in interface org.opengis.geometry.DirectPosition
Parameters:
dimension - The dimension, which must be 0.
value - the ordinate value.
Throws:
java.lang.IndexOutOfBoundsException - if the specified dimension is out of bounds.

setLocation

public void setLocation(org.opengis.geometry.DirectPosition position)
                 throws org.opengis.geometry.MismatchedDimensionException
Set this coordinate to the specified direct position. If the specified position contains a coordinate reference system, then the CRS for this position will be set to the CRS of the specified position.

Parameters:
position - The new position for this point.
Throws:
org.opengis.geometry.MismatchedDimensionException - if this point doesn't have the expected dimension.

hashCode

public int hashCode()
Returns a hash value for this coordinate.

Specified by:
hashCode in interface org.opengis.geometry.DirectPosition
Overrides:
hashCode in class AbstractDirectPosition
Returns:
A hash code value for this position.

clone

public DirectPosition1D clone()
Returns a copy of this position.

Overrides:
clone in class java.lang.Object
