Examples with Convert javax.persistence.Convert used on opensource projects

Example 1 with Convert

use of javax.persistence.Convert in project hibernate-orm by hibernate.

the class ComponentPropertyHolder method processAttributeConversions.

	 *     <li>@Converts annotation at the Embedded attribute level</li>
	 * </ol>
	 * <p/>
	 * The order is important to ensure proper precedence.
	 * <p/>
	 * {@literal @Convert/@Converts} annotations at the Embeddable attribute level are handled in the calls to
	 * {@link #startingProperty}.  Duplicates are simply ignored there.
