示例1: getAnnotationValues

import org.hibernate.annotations.OptimisticLock; //导入依赖的package包/类
/**
 * Get the set of annotation values for this annotation type
 * @return the set of annotation values for this annotation type
 */
@OneToMany(fetch=FetchType.LAZY,
           cascade={ CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REMOVE },
           mappedBy="annotationType")
@ToMany(hasNonconventionalMutation=true /* model unit tests don't handle Maps yet, tested in AnnotationTypeTest#testAnnotationValues */)             
@MapKey(name="reagent")
@OptimisticLock(excluded=true)
@org.hibernate.annotations.Cascade(value={org.hibernate.annotations.CascadeType.SAVE_UPDATE, org.hibernate.annotations.CascadeType.DELETE})
// removing, as this inconveniently forces us to access all reagents before looking for them in the map collection  @org.hibernate.annotations.LazyCollection(LazyCollectionOption.EXTRA)
public Map<Reagent,AnnotationValue> getAnnotationValues()
{
  return _values;
}

	Lob lob = property != null ? property.getAnnotation( Lob.class ) : null;
	prop.setLob( lob != null );

	prop.setInsertable( insertable );
	prop.setUpdateable( updatable );

	// this is already handled for collections in CollectionBinder...
	if ( Collection.class.isInstance( value ) ) {
		prop.setOptimisticLocked( ( (Collection) value ).isOptimisticLocked() );
	}
	else {

				? property.getAnnotation( OptimisticLock.class )
				: null;
		if ( lockAnn != null ) {

			if ( lockAnn.excluded() && (
					property.isAnnotationPresent( javax.persistence.Version.class )
							|| property.isAnnotationPresent( Id.class )
							|| property.isAnnotationPresent( EmbeddedId.class ) ) ) {
				throw new AnnotationException(
						"@OptimisticLock.exclude=true incompatible with @Id, @EmbeddedId and @Version: "
								+ StringHelper.qualify( holder.getPath(), name )
				);
			}
		}
		final boolean isOwnedValue = !isToOneValue( value ) || insertable; // && updatable as well???
		final boolean includeInOptimisticLockChecks = ( lockAnn != null )
				? ! lockAnn.excluded()

	}

	LOG.tracev( "Cascading {0} with {1}", name, cascade );
	this.mappingProperty = prop;
	return prop;
}
