CMYCoordinateSystem

public CMYCoordinateSystem(RealTupleType reference)
                    throws VisADException

construct a CMYCoordinateSystem with given reference

Parameters:

reference - - reference RealTupleType

Throws:

VisADException

Method Detail

toReference

public double[][] toReference(double[][] tuples)
                       throws VisADException

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.

Specified by:

toReference in class CoordinateSystem

Parameters:

tuples - array of values assumed to be in coordinateSystem units. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of double values in reference coordinates and Unit-s.

Throws:

VisADException - if problem with conversion.

fromReference

public double[][] fromReference(double[][] tuples)
                         throws VisADException

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.

Specified by:

fromReference in class CoordinateSystem

Parameters:

tuples - array of values assumed to be in reference Unit-s. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of double values in CoordinateSystem Unit-s.

Throws:

VisADException - if problem with conversion.

toReference

public float[][] toReference(float[][] tuples)
                      throws VisADException

Convert RealTuple values to Reference coordinates; for efficiency, input and output values are passed as float[][] arrays rather than RealTuple[] arrays; the array organization is float[tuple_dimension][number_of_tuples]; can modify and return argument array.

Overrides:

toReference in class CoordinateSystem

Parameters:

tuples - array of values assumed to be in coordinateSystem units. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of float values in reference coordinates and Unit-s.

Throws:

VisADException - if problem with conversion.

fromReference

public float[][] fromReference(float[][] tuples)
                        throws VisADException

Convert RealTuple values from Reference coordinates; for efficiency, input and output values are passed as float[][] arrays rather than RealTuple[] arrays; the array organization is float[tuple_dimension][number_of_tuples]; can modify and return argument array.

Overrides:

fromReference in class CoordinateSystem

Parameters:

tuples - array of values assumed to be in reference Unit-s. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of float values in CoordinateSystem Unit-s.

Throws:

VisADException - if problem with conversion.

equals

public boolean equals(java.lang.Object cs)

Indicates whether or not this instance is equal to an object.

Specified by:

equals in class CoordinateSystem

Parameters:

cs - - the object in question.

Returns:

true if and only if this instance equals cs.
