Example 1 with OrdinalEnumValueConverter

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

the class EnumType method setParameterValues.

    // 2) we are not passed a ParameterType - generally this indicates a hbm.xml binding case.
