Example 1 with MultiPropertyMapper

use of org.hibernate.envers.internal.entities.mapper.MultiPropertyMapper in project hibernate-orm by hibernate.

the class CollectionMetadataGenerator method addValueToMiddleTable.

/**
 * @param value Value, which should be mapped to the middle-table, either as a relation to another entity,
 * or as a simple value.
 * @param xmlMapping If not <code>null</code>, xml mapping for this value is added to this element.
 * @param queryGeneratorBuilder In case <code>value</code> is a relation to another entity, information about it
 * should be added to the given.
 * @param prefix Prefix for proeprty names of related entities identifiers.
 * @param joinColumns Names of columns to use in the xml mapping, if this array isn't null and has any elements.
 *
 * @return Data for mapping this component.
