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

Example 1 with DiscriminatorColumn

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

the class AnnotationBinder method processSingleTableDiscriminatorProperties.

/**
 * Process all discriminator-related metadata per rules for "single table" inheritance
 */
private static AnnotatedDiscriminatorColumn processSingleTableDiscriminatorProperties(XClass clazzToProcess, MetadataBuildingContext context, InheritanceState inheritanceState, EntityBinder entityBinder) {
    final boolean isRoot = !inheritanceState.hasParents();
    AnnotatedDiscriminatorColumn discriminatorColumn = null;
    jakarta.persistence.DiscriminatorColumn discAnn = clazzToProcess.getAnnotation(jakarta.persistence.DiscriminatorColumn.class);
    DiscriminatorType discriminatorType = discAnn != null ? discAnn.discriminatorType() : DiscriminatorType.STRING;
    DiscriminatorFormula discFormulaAnn = getOverridableAnnotation(clazzToProcess, DiscriminatorFormula.class, context);
    if (isRoot) {
        discriminatorColumn = buildDiscriminatorColumn(discriminatorType, discAnn, discFormulaAnn, context);
    }
    if (discAnn != null && !isRoot) {
        LOG.invalidDiscriminatorAnnotation(clazzToProcess.getName());
    }
    final String discriminatorValue = clazzToProcess.isAnnotationPresent(DiscriminatorValue.class) ? clazzToProcess.getAnnotation(DiscriminatorValue.class).value() : null;

        entityBinder.setForceDiscriminator(discriminatorOptions.force());
        entityBinder.setInsertableDiscriminator(discriminatorOptions.insert());
    }
    return discriminatorColumn;
}

Example 2 with DiscriminatorColumn

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

the class JPAXMLOverriddenAnnotationReader method getDiscriminatorColumn.

Example 3 with DiscriminatorColumn

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

the class AnnotationBinder method processJoinedDiscriminatorProperties.

/**
 * Process all discriminator-related metadata per rules for "joined" inheritance
 */
private static AnnotatedDiscriminatorColumn processJoinedDiscriminatorProperties(XClass clazzToProcess, MetadataBuildingContext context, InheritanceState inheritanceState, EntityBinder entityBinder) {
