Examples with Index jakarta.persistence.Index used on opensource projects

Example 1 with Index

use of jakarta.persistence.Index in project hibernate-orm by hibernate.

the class JPAXMLOverriddenAnnotationReader method buildIndex.

private static void buildIndex(AnnotationDescriptor annotation, List<JaxbIndex> elements) {
    Index[] indexes = new Index[elements.size()];
    int i = 0;
    for (JaxbIndex element : elements) {
        AnnotationDescriptor indexAnn = new AnnotationDescriptor(Index.class);
        copyAttribute(indexAnn, "name", element.getName(), false);
        copyAttribute(indexAnn, "column-list", element.getColumnList(), true);
        copyAttribute(indexAnn, "unique", element.isUnique(), false);
        indexes[i++] = AnnotationFactory.create(indexAnn);
    }
    annotation.setValue("indexes", indexes);
}
