Example 1 with NamedEnumValueConverter

use of org.hibernate.metamodel.model.convert.internal.NamedEnumValueConverter in project hibernate-orm by hibernate.

the class EnumType method setParameterValues.

    // speaking this indicates the annotation-binding case, and the passed ParameterType
    // represents information about the attribute and annotation
    // 2) we are not passed a ParameterType - generally this indicates a hbm.xml binding case.
