```
public class RegionPrms
extends BasePrms
```
A class used to store keys for region configuration settings. The settings are used to create instances of RegionDescription.
The number of description instances is gated by names. For other parameters, if fewer values than names are given, the remaining instances will use the last value in the list. See $JTESTS/hydra/hydra.txt for more details.
Unused parameters default to null, except where noted. This uses the product default, except where noted.
Values, fields, and subfields of a parameter can be set to BasePrms.DEFAULT, except where noted. This uses the product default, except where noted.
Values, fields, and subfields can be set to BasePrms.NONE where noted, with the documented effect.
Values, fields, and subfields of a parameter can use oneof, range, or robing except where noted, but each description created will use a fixed value chosen at test configuration time. Use as a task attribute is illegal.
Subfields are order-dependent, as stated in the javadocs for parameters that use them.
