DirectPosition1D
public DirectPosition1D()Constructs a position initialized to (0) with anullcoordinate reference system. -
DirectPosition1D
Constructs a position with the specified coordinate reference system.- Parameters:
crs- the coordinate reference system.
-
DirectPosition1D
public DirectPosition1D(double coordinate) Constructs a 1D position from the specified coordinate.- Parameters:
coordinate- the coordinate value.
-
DirectPosition1D
Constructs a position initialized to the values parsed from the given string in Well Known Text (WKT) format. The given string is typically aPOINTelement like below:POINT(6)
- Parameters:
wkt- thePOINTor other kind of element to parse.- Throws:
IllegalArgumentException- if the given string cannot be parsed.MismatchedDimensionException- if the given point is not one-dimensional.- See Also:

Method Details
-
getDimension
public final int getDimension()The length of coordinate sequence (the number of entries). This is always 1 forDirectPosition1Dobjects.- Specified by:
getDimensionin interfaceDirectPosition- Returns:
- the dimensionality of this position.
-
getCoordinateReferenceSystem
Returns the coordinate reference system in which the coordinate is given. May benullif this particularDirectPositionis included in a larger object with such a reference to a CRS.- Specified by:
getCoordinateReferenceSystemin interfaceDirectPosition- Overrides:
getCoordinateReferenceSystemin classAbstractDirectPosition- Returns:
- the coordinate reference system, or
null.
-
setCoordinateReferenceSystem
Sets the coordinate reference system in which the coordinate is given.- Parameters:
crs- the new coordinate reference system, ornull.
-
getCoordinate
public final double[] getCoordinate()Returns a sequence of numbers that hold the coordinate of this position in its reference system.API note: This method is final for ensuring consistency with thecoordinatefield, which is public.- Specified by:
getCoordinatein interfaceDirectPosition- Overrides:
getCoordinatein classAbstractDirectPosition- Returns:
- the coordinates.
-
getOrdinate
Returns the coordinate at the specified dimension.API note: This method is final for ensuring consistency with thecoordinatefield, which is public.- Specified by:
getOrdinatein interfaceDirectPosition- Parameters:
dimension- the dimension, which must be 0.- Returns:
- the
coordinate. - Throws:
IndexOutOfBoundsException- if the specified dimension is out of bounds.
-
setOrdinate
Sets the coordinate value along the specified dimension.- Specified by:
setOrdinatein interfaceDirectPosition- Overrides:
setOrdinatein classAbstractDirectPosition- Parameters:
dimension- the dimension, which must be 0.value- the coordinate value.- Throws:
IndexOutOfBoundsException- if the specified dimension is out of bounds.
-
setLocation
Sets this coordinate to the specified direct position. If the specified position contains a coordinate reference system (CRS), then the CRS for this position will be set to the CRS of the specified position.- Overrides:
setLocationin classAbstractDirectPosition- Parameters:
position- the new position for this point.- Throws:
MismatchedDimensionException- if this point doesn't have the expected dimension.
-
toString
Formats this position in the Well Known Text (WKT) format. The output is like below:
The string returned by this method can be parsed by thePOINT(coordinate)
DirectPosition1Dconstructor.- Overrides:
toStringin classAbstractDirectPosition- Returns:
- this position as a
POINTin Well Known Text (WKT) format.
-
clone
Returns a copy of this position. -
hashCode
public int hashCode()Returns a hash value for this coordinate tuple. This method returns a value compliant with the contract documented in theDirectPosition.hashCode()javadoc. Consequently, it should be possible to mix differentDirectPositionimplementations in the same hash map.- Specified by:
hashCodein interfaceDirectPosition- Overrides:
hashCodein classAbstractDirectPosition- Returns:
- a hash code value for this position.
