org.hibernate.validator.internal.metadata.aggregated.ExecutableMetaData
An aggregated view of the constraint related meta data for a given method or constructors and in (case of methods) 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 ConstrainedExecutable} objects to it. Instances are read-only aftercreation.

Identity is solely based on the method's name and parameter types, hence sets and similar collections of this type may only be created in the scope of one Java type.
