Examples with HibernateEntityValueEncoder org.apache.tapestry5.hibernate.web.internal.HibernateEntityValueEncoder used on opensource projects

Example 1 with HibernateEntityValueEncoder

use of org.apache.tapestry5.hibernate.web.internal.HibernateEntityValueEncoder in project tapestry-5 by apache.

the class HibernateModule method contributeValueEncoderSource.

/**
 * Contributes {@link ValueEncoderFactory}s for all registered Hibernate entity classes. Encoding and decoding are
 * based on the id property value of the entity using type coercion. Hence, if the id can be coerced to a String and
 * back then the entity can be coerced.
