class CombinationGenerator;Given input such as {{0, 1}, {2}, {3, 4}}, yields every tuple formed by picking one choice per variable: {0, 2, 3}, {0, 2, 4}, {1, 2, 3}, {1, 2, 4}. The outer range is the variable space; each inner range is the set of choices for that variable.
| Name | Description |
|---|---|
CombinationGenerator [constructor] | Construct a generator over the given per-variable choice lists. |
generate | Invoke Callback for every combination in the choice space. |
numCombinations | Return the product of the sizes of all per-variable choice lists. This is the maximum number of times the generate callback may be called. |
