Detailed Description

Supports modification of certain region attributes after the region has been created.

It is required that the attributes be completely initialized using an RegionAttributesFactory before creating the region. AttributesMutator can be applied to adjusting and tuning a subset of attributes that are modifiable at runtime.

The setter methods all return the previous value of the attribute.
