Examples with AnyMetaDef org.hibernate.annotations.AnyMetaDef used on opensource projects

Example 1 with AnyMetaDef

use of org.hibernate.annotations.AnyMetaDef in project hibernate-orm by hibernate.

the class BinderHelper method buildAnyValue.

public static Any buildAnyValue(String anyMetaDefName, Ejb3JoinColumn[] columns, javax.persistence.Column metaColumn, PropertyData inferredData, boolean cascadeOnDelete, Nullability nullability, PropertyHolder propertyHolder, EntityBinder entityBinder, boolean optional, MetadataBuildingContext context) {

        for (Ejb3JoinColumn column : columns) {
            column.setNullable(false);
        }
    }
    Ejb3Column[] metaColumns = Ejb3Column.buildColumnFromAnnotation(new javax.persistence.Column[] { metaColumn }, null, nullability, propertyHolder, inferredData, entityBinder.getSecondaryTables(), context);
    //set metaColumn to the right table
    for (Ejb3Column column : metaColumns) {
        column.setTable(value.getTable());
    }
    //meta column
    for (Ejb3Column column : metaColumns) {
        column.linkWithValue(value);
    }
    //id columns
    final String propertyName = inferredData.getPropertyName();
    Ejb3Column.checkPropertyConsistency(columns, propertyHolder.getEntityName() + "." + propertyName);
    for (Ejb3JoinColumn column : columns) {
        column.linkWithValue(value);

}

Example 2 with AnyMetaDef

use of org.hibernate.annotations.AnyMetaDef in project hibernate-orm by hibernate.

the class BinderHelper method bindAnyMetaDefs.

public static void bindAnyMetaDefs(XAnnotatedElement annotatedElement, MetadataBuildingContext context) {
    AnyMetaDef defAnn = annotatedElement.getAnnotation(AnyMetaDef.class);
    AnyMetaDefs defsAnn = annotatedElement.getAnnotation(AnyMetaDefs.class);
    boolean mustHaveName = XClass.class.isAssignableFrom(annotatedElement.getClass()) || XPackage.class.isAssignableFrom(annotatedElement.getClass());
    if (defAnn != null) {
        checkAnyMetaDefValidity(mustHaveName, defAnn, annotatedElement);
        bindAnyMetaDef(defAnn, context);
    }
    if (defsAnn != null) {
        for (AnyMetaDef def : defsAnn.value()) {
            checkAnyMetaDefValidity(mustHaveName, def, annotatedElement);
            bindAnyMetaDef(def, context);
        }
    }
