public class InverseCoordinateSystem
extends CoordinateSystem

InverseCoordinateSystem is the VisAD CoordinateSystem class for inverting other CoordinateSystems.

Serialized Form

Constructor Summary
InverseCoordinateSystem(RealTupleType reference, CoordinateSystem inv)
          construct a CoordinateSystem that whose transforms invert the transforms of inverse (i.e., toReference and fromReference are switched); for example, this could be used to define Cartesian coordinates releative to a refernce in spherical coordinates
 
Method Summary
 boolean equals(java.lang.Object cs)
          check for equality of CoordinateSystem objects; must test for cs == null
 double[][] fromReference(double[][] tuples)
          convert RealTuple values from Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array
 float[][] fromReference(float[][] tuples)
          convert RealTuple values from Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array for efficiency, subclasses should override this implementation
 double[][] toReference(double[][] tuples)
          convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array
 float[][] toReference(float[][] tuples)
          convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array; for efficiency, subclasses should override this implementation

Specified by:
fromReference in class CoordinateSystem
Throws:
VisADException

toReference

public float[][] toReference(float[][] tuples)
                      throws VisADException
Description copied from class: CoordinateSystem
convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as double[][] arrays rather than RealTuple[] arrays; the array organization is double[tuple_dimension][number_of_tuples]; can modify and return argument array; for efficiency, subclasses should override this implementation

Overrides:
