public class MultiDimensionalFloatArray extends AbstractBasicMultiDimensionalArray<java.lang.Float>
There is no enforced limit to the number of dimensions, but internally this is mapped to a standard Java array, which can only hold a limited number of elements.
Please note that although this implements
MultiDimensionalReadAccess.getElement(int...)
and
MultiDimensionalAccess.setElement(Object, int...)
to be used in generic circumstances the recommended methods
for getting and setting are
getValue(int...)
and
setValue(float, int...)
because they avoid unnecessary boxing.

sizes - of the dimensions of this array,

an oblong array with size 2 in the first,
size 3 in the second, and size 4 in the third
dimension, containing 2*3*4 = 24 elementspublic MultiDimensionalFloatArray(@NotNull MultiDimensionalFloatArray baseArray, @NotNull Function1<int[],int[]> indexConverter, int... sizes)
This constructs a new read/write access to the given baseArray
allowing you to do nearly everything. As this gives a lot of power
be sure that the indexConverter does "the right thing",
otherwise runtime exceptions will occur.
baseArray - basic array to which accesses to this array are mappedindexConverter - index converter which converts indexes into this array
to indexes into the basic array. Failing to fulfill
the restrictions (parameter length has to be
the same length as the following sizes, and
fit into their ranges, and the result indexes have
to fit the restrictions of the baseArray
will result in runtime errorssizes - sizes of the dimensions of this array@NotNull public java.lang.Float getElement(int... indexes)

MultiDimensionalAccess
This default implementation is only slightly more efficient than
a get and set sequence,
but implementing classes are encouraged to provide better implementations
(e.g. the index linearization has only to happen once).
operator - operator to apply to the value at the location defined by the given indexes.
When used on a specialized primitive type array the operator
will never receive null, and must not return null.
In other cases this depends on usage.indexes - MultiDimensional.getNumDimensions() indexes inside the bounds

This uses MultiIndexLinearizer.getHighFastSequencer()
