This class represents an iterator (implemented in the output port pattern) over all distinct N-tuples, which can be chosen from {@code N} sets of integers. More formally,for {@code N} integer arrays: array₁,array₂,...,array_N, this class allows to iterate over all possible integer arrays of the form [i₁, i₂,...,i_N], where all numbers numbers i_j are different and i₁ is chosen from array₁, i₂ is chosen from array₂ and so on.

Consider the example:

 int[] a1 = {1, 2, 3}; int[] a2 = {2, 3}; DistinctCombinationsPort dcp = new DistinctCombinationsPort(a1, a2); int[] tuple; while ((tuple = dcp.take()) != null) System.out.println(Arrays.toString(tuple));

This code will produce the following sequence: [1, 2] [1, 3] [2, 3] [3, 2]

This class is implemented via output port pattern and the calculation of the next tuple occurs only on the invocation of {@link #take()}. Note: method {@link #take()} returns the same reference on each invocation.So, if it is needed not only to obtain the information from {@link #take()}, but also save the result, it is necessary to clone the returned array.
