DimensionNameSpaceTranslator

public DimensionNameSpaceTranslator()

Method Detail

addInvariant

public void addInvariant(int dim)

Specify a dimension index that should be cross copied regardless of naming. For example, if dimension 0 is always duration, addInvariant(0) and sourceArray[0] will be copied across to destArray[0] regardless of naming.

setSourceDimensionNameSpace

public void setSourceDimensionNameSpace(DimensionNameSpace dns)

setDestinationDimensionNameSpace

public void setDestinationDimensionNameSpace(DimensionNameSpace dns)

translate

public double[] translate(double[] sourceDar,
                          double[] resultDar)

Copy as many values from source array to dest array as possible, pulling values by name. Then run through dimension invariants and copy those across (for example dim 0 to dim 0) Other values set to destinationNameSpace.getDefault(dim)

Uses preallocated double[] for destination.

Returns:

modified resultDar, translated from source

translate

public double[] translate(double[] sourceDar)

Copy as many values from source array to dest array as possible, pulling values by name. Then run through dimension invariants and copy those across (for example dim 0 to dim 0) Other values set to Double.NEGATIVE_INFINITY

Allocates new double[] for destination.

Returns:

modified resultDar, translated from source

main

public static void main(java.lang.String[] args)
