abstract boolean |
isOneToOne()

boolean |
isReferenceToPrimaryKey()
Does this association foreign key reference the primary key of the other table? Otherwise, it references a property-ref. |
boolean |
isSame(Object x,
Object y,
EntityMode entityMode)
Two entities are considered the same when their instances are the same. |
boolean |
isXMLElement()
|
Object |
loadByUniqueKey(String entityName,
String uniqueKeyPropertyName,
Object key,
SessionImplementor session)
Load an instance by a unique key that is not the primary key. |
Object |
nullSafeGet(ResultSet rs,
String[] names,
SessionImplementor session,
Object owner)

Object |
nullSafeGet(ResultSet rs,
String name,

Object |
replace(Object original,
Object target,
SessionImplementor session,
Object owner,
Map copyCache)
During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging. |
Object |
resolve(Object value,
SessionImplementor session,
Object owner)
Resolve an identifier or unique key value |
protected Object |
resolveIdentifier(Serializable id,
SessionImplementor session)
Resolve an identifier via a load. |
void |
setToXMLNode(org.dom4j.Node node,
Object value,
SessionFactoryImplementor factory)
A representation of the value to be embedded in an XML element. |
String |
toLoggableString(Object value,
SessionFactoryImplementor factory)

String |
toString()
Generates a string representation of this type. |

protected EntityType(String entityName, String uniqueKeyPropertyName, boolean eager, boolean isEmbeddedInXML, boolean unwrapProxy)
entityName
- The name of the associated entity.uniqueKeyPropertyName
- The property-ref name, or null if we
reference the PK of the associated entity.eager
- Is eager fetching enabled.isEmbeddedInXML
- Should values of this mapping be embedded in XML modes?unwrapProxy
- Is unwrapping of proxies allowed for this association; unwrapping
says to return the "implementation target" of lazy prooxies; typically only possible
with lazy="no-proxy".Method Detail |
