# Class: com.pnfsoftware.jeb.util.base.Tuples

Integer tuples generator routines.

## Constructor: Tuples


## Static Method: generateIntegerTuples
- parameter: `n`, type: `int`
- return type: `java.util.List<java.util.List<java.lang.Integer>>`

Description: Generate all tuples containing the numbers 0 to n\-1. Be careful, n\! tuples will be generated. 

 For instance, for n=3, the tuples are:  

```

 (0,1,2), (0,2,1), (1,0,2), (1,2,0), (2,0,1), (2,1,0)
 
```
parameter: n: the tuple size
return: the list of tuples, or null if `n <= 0`
