toReference

public double[][] toReference(double[][] 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.

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 Units.

Throws:

VisADException - if problem with conversion.

fromReference

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

Description copied from class: CoordinateSystem

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 Units. Input array is not guaranteed to be immutable and could be used for return.

Returns:

array of double values in CoordinateSystem Units.

Throws:

VisADException - if problem with conversion.

equals

public boolean equals(Object cs)

Description copied from class: CoordinateSystem

Indicates whether or not this instance is equal to an object (note must test for cs == null).

Specified by:

equals in class CoordinateSystem

Parameters:

cs - the object in question.

Returns:

true if and only if this instance equals cs.

main

public static void main(String[] args)
                 throws VisADException

Throws:

VisADException
