org.hibernate.validator.metadata.AggregatedMethodMetaData

An aggregated view of the constraint related meta data for a given method and all the methods in the inheritance hierarchy which it overrides or implements.

Instances are retrieved by creating a {@link Builder} and adding all required{@link MethodMetaData} objects to it. Instances are read-only after creation.
