asArray1D

public final Array1D<N> asArray1D()

A utility facade that conveniently/consistently presents the BasicArray as a one-dimensional array. Note that you will modify the actual array by accessing it through this facade.

Disregards the array structure, and simply treats it as one-domensional.

asArray2D

public final Array2D<N> asArray2D(int aRowDim,
                                  int aColDim)

A utility facade that conveniently/consistently presents the BasicArray as a two-dimensional array. Note that you will modify the actual array by accessing it through this facade.

If "this" has more than two dimensions then only the first plane of the first cube of the first... is used/accessed. If this only has one dimension then everything is assumed to be in the first column of the first plane of the first cube...

asArrayAnyD

public final ArrayAnyD<N> asArrayAnyD(int[] aStructure)

A utility facade that conveniently/consistently presents the BasicArray as a multi-dimensional array. Note that you will modify the actual array by accessing it through this facade.

toString
