示例1: CachedNaturalId
import org.hibernate.type.Type; //导入方法依赖的package包/类
public CachedNaturalId(EntityPersister persister, Object[] values) {
this.persister = persister;
this.values = values;
final int prime = 31;
int hashCodeCalculation = 1;
hashCodeCalculation = prime * hashCodeCalculation + persister.hashCode();
final int[] naturalIdPropertyIndexes = persister.getNaturalIdentifierProperties();
naturalIdTypes = new Type[ naturalIdPropertyIndexes.length ];
int i = 0;
for ( int naturalIdPropertyIndex : naturalIdPropertyIndexes ) {
final Type type = persister.getPropertyType( persister.getPropertyNames()[ naturalIdPropertyIndex ] );
naturalIdTypes[i] = type;
final int elementHashCode = values[i] == null ? 0 :type.getHashCode( values[i], persister.getFactory() );
hashCodeCalculation = prime * hashCodeCalculation + elementHashCode;
i++;
}
this.hashCode = hashCodeCalculation;
}
示例2: NaturalIdCacheKey
import org.hibernate.type.Type; //导入方法依赖的package包/类
/**
* Construct a new key for a caching natural identifier resolutions into the second level cache.
* Note that an entity name should always be the root entity name, not a subclass entity name.
*
* @param naturalIdValues The naturalIdValues associated with the cached data
* @param persister The persister for the entity
* @param session The originating session
*/

import org.hibernate.type.Type; //导入方法依赖的package包/类
private int calculateHashCode(Type type, SessionFactoryImplementor factory) {
