Example 2 with EmbeddedCollectionPart

use of org.hibernate.metamodel.mapping.internal.EmbeddedCollectionPart in project hibernate-orm by hibernate.

the class EmbeddableAccessTests method verifyRuntimeModel.

@Test

    // - if we find the property annotations, the attribute names will be
    // `firstName` and `lastName`, and the columns `first_name` and `last_name`
    // - otherwise, we have property and column names being `first` and `last`
