Package org.apache.sis.coverage.grid

Class FractionalGridCoordinates.Position

java.lang.Object
org.apache.sis.coverage.grid.FractionalGridCoordinates
org.apache.sis.coverage.grid.FractionalGridCoordinates.Position
All Implemented Interfaces:
Serializable, org.opengis.geometry.coordinate.Position, org.opengis.geometry.DirectPosition
Enclosing class:
FractionalGridCoordinates
static final class FractionalGridCoordinates.Position extends FractionalGridCoordinates implements org.opengis.geometry.DirectPosition
A grid coordinates viewed as a DirectPosition. This class is used only for coordinate transformation. We do not want to make this class public in order to avoid the abuse of DirectPosition as a storage of grid coordinates.

Note this this class does not comply with the contract documented in DirectPosition.equals(Object) and DirectPosition.hashCode() javadoc. This is another reason for not making this class public.

    • getDirectPosition

      public org.opengis.geometry.DirectPosition getDirectPosition()
      Returns the direct position, which is this object itself.
      Specified by:
      getDirectPosition in interface org.opengis.geometry.coordinate.Position

    • getCoordinateReferenceSystem

      public org.opengis.referencing.crs.CoordinateReferenceSystem getCoordinateReferenceSystem()
      Grid coordinates have no coordinate reference system.
      Specified by:
      getCoordinateReferenceSystem in interface org.opengis.geometry.DirectPosition

    • getCoordinate

      public double[] getCoordinate()
      Returns all coordinate values.
      Specified by:
      getCoordinate in interface org.opengis.geometry.DirectPosition

    • getOrdinate

      public double getOrdinate(int dimension)
      Returns the coordinate value at the given dimension.
      Specified by:
      getOrdinate in interface org.opengis.geometry.DirectPosition

    • setOrdinate

      public void setOrdinate(int dimension, double value)
      Sets the coordinate value at the given dimension.
      Specified by:
      setOrdinate in interface org.opengis.geometry.DirectPosition

    • toPosition

      public org.opengis.geometry.DirectPosition toPosition(org.opengis.referencing.operation.MathTransform gridToCRS) throws org.opengis.referencing.operation.TransformException
      Returns the grid coordinates converted to a geospatial position using the given transform.
      Overrides:
      toPosition in class FractionalGridCoordinates
      Parameters:
      gridToCRS - the transform to apply on grid coordinates.
      Returns:
      the grid coordinates converted using the given transform.
      Throws:
      org.opengis.referencing.operation.TransformException - if the grid coordinates cannot be converted by gridToCRS.
