Class InverseCoordinateSystem

java.lang.Object
  visad.CoordinateSystem
      visad.InverseCoordinateSystem

All Implemented Interfaces:

java.io.Serializable

public class InverseCoordinateSystem
extends CoordinateSystem

InverseCoordinateSystem is the VisAD CoordinateSystem class for inverting other CoordinateSystems.

See Also:

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
