One or more Amazon Web Services Regions where the provisioned product will be available.

<p>
Applicable only to a <code>CFN_STACKSET</code> provisioned product type.
</p>
<p>
The specified Regions should be within the list of Regions from the <code>STACKSET</code> constraint. To get the
list of Regions in the <code>STACKSET</code> constraint, use the <code>DescribeProvisioningParameters</code>
operation.
</p>
<p>
If no values are specified, the default value is all Regions from the <code>STACKSET</code> constraint.
</p>
<p>
<b>NOTE:</b> This method appends the values to the existing list (if any). Use
{@link #setStackSetRegions(java.util.Collection)} or {@link #withStackSetRegions(java.util.Collection)} if you
want to override the existing values.
