public final class DefaultPartitionAttributesBuilder extends java.lang.Object implements PartitionAttributesBuilder
PartitionAttributesBuilder.
This class provides a relatively low memory overhead (when compared to TreeMap) for a
PartitionAttributes. The goals are to provide fast Object.equals(Object) and
Object.hashCode() which do not require intermediate object allocation and pointer traversal
(e.g. Iterator).
