cc.redberry.core.combinatorics.IntTuplesPort
This class allows to iterate over all N-tuples (not necessary to be distinct), which can be chosen from {@code N} arrays of integers of the formarray_i = [0, 1, 2, ..., K_i].

For example, if a set of arrays length is {K_i} = [2,3,2], then the following tuples will be produced [0, 0, 0] [0, 0, 1] [0, 1, 0] [0, 1, 1] [0, 2, 0] [0, 2, 1] [1, 0, 0] [1, 0, 1] [1, 1, 0] [1, 1, 1] [1, 2, 0] [1, 2, 1]

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.
