public class SmallTwoDimensionalFloatArray extends TwoDimensionalFloatReadAccess.Base implements TwoDimensionalFloatAccess
This internally maps to a one-dimensional float array which is created faster.
Because of the mapping the size of the dimensions is restricted in a way that the
number of elements in this array (i.e. the multiplication of its X and Y size) is less
than Integer.MAX_VALUE. Use TwoDimensionalFloatArray if you are not
sure to always obey this restriction.
