public interface LazyInitializer
Handles fetching of the underlying entity for a proxy
Method Summary | |
---|---|
String |
getEntityName()
The entity-name of the entity our owning proxy represents. |
Serializable |
getIdentifier()
Retrieve the identifier value for the enity our owning proxy represents. |
Object |
getImplementation()
Return the underlying persistent object, initializing if necessary |
Object |
getImplementation(SessionImplementor session)
Return the underlying persistent object in the given session, or null if not contained in this session's persistence context. |
Class |
getPersistentClass()
Get the actual class of the entity. |
SessionImplementor |
getSession()
Get the session to which this proxy is associated, or null if it is not attached. |
void |
initialize()
Initialize the proxy, fetching the target entity if necessary. |
boolean |
isUninitialized()
Is the proxy uninitialzed? |
boolean |
isUnwrap()
|
void |
setIdentifier(Serializable id)
Set the identifier value for the enity our owning proxy represents. |
void |
setImplementation(Object target)
Initialize the proxy manually by injecting its target. |
void |
setSession(SessionImplementor session)

void |
setUnwrap(boolean unwrap)
|
void |
unsetSession()
