| 16 | * This class is a concrete <code>IParamsAssigner</code> implementation | |
| 17 | * providing a cyclic parameters assignment policy.<br> | |
| 18 | * This means that should a configured runner have multiple parameters-sets | |
| 19 | * associated with it, this particular assigner would iterate over all the | |
| 20 | * available parameters-set and assign them to the runner following the order in | |
| 21 | * which they compare in the <code>jtr.xml</code> configuration file. Each | |
| 22 | * assignment will be performed at the beginning of each run.<br> | |
| 23 | * The number of runs has priority over the number of configured | |
| 24 | * parameters-sets. | |
