Method Detail

initialize

void initialize()
                throws javax.persistence.PersistenceException

Initialize the proxy, fetching the target entity if necessary.

Throws:

javax.persistence.PersistenceException - the persistence exception

getIdentifier

Object getIdentifier()

Retrieve the identifier value for the enity our owning proxy represents.

Returns:

The identifier value.

setIdentifier

void setIdentifier(Object id)

Set the identifier value for the enity our owning proxy represents.

Parameters:

id - The identifier value.

getEntityName

String getEntityName()

The entity-name of the entity our owning proxy represents.

Returns:

The entity-name.

getPersistentClass

Class<?> getPersistentClass()

Get the actual class of the entity. Generally, getEntityName() should be used instead.

Returns:

The actual entity class.

isUninitialized

boolean isUninitialized()

Is the proxy uninitialzed?.

Returns:

True if uninitialized; false otherwise.

getPersistenceDelegator

PersistenceDelegator getPersistenceDelegator()

Get the session to which this proxy is associated, or null if it is not attached.

Returns:

The associated session.

unsetPersistenceDelegator

void unsetPersistenceDelegator()

Unset this initializer's reference to session. It is assumed that the caller is also taking care or cleaning up the owning proxy's reference in the persistence context.

setUnwrap

void setUnwrap(boolean unwrap)

Sets the unwrap.

Parameters:

unwrap - the new unwrap

isUnwrap

boolean isUnwrap()

Checks if is unwrap.

Returns:

true, if is unwrap

getImplementation

Object getImplementation()

setImplementation

void setImplementation(Object paramObject)

setOwner

void setOwner(Object owner)
              throws javax.persistence.PersistenceException

Throws:

javax.persistence.PersistenceException

getOwner

Object getOwner()
                throws javax.persistence.PersistenceException

Throws:

javax.persistence.PersistenceException

setInitialized

void setInitialized(boolean initialized)
