public boolean isReadOnly()

Is the proxy read-only?. The read-only/modifiable setting is not available when the proxy is detached or its associated session is closed. To check if the read-only/modifiable setting is available:

Returns:boolean

true, if this proxy is read-only; false, otherwise

Exceptions

TransientObjectException:: if the proxy is detached (getSession() == null)
SessionException:: if the proxy is associated with a sesssion that is closed

setImplementation

back to summary

public void setImplementation(Object target)

Initialize the proxy manually by injecting its target.

Parameters

target:Object: The proxy target (the actual entity being proxied).

setReadOnly back to summary

setReadOnly	back to summary
public void setReadOnly(boolean readOnly) Set an associated modifiable proxy to read-only mode, or a read-only proxy to modifiable mode. If the proxy is currently initialized, its implementation will be set to the same mode; otherwise, when the proxy is initialized, its implementation will have the same read-only/ modifiable setting as the proxy. In read-only mode, no snapshot is maintained and the instance is never dirty checked. If the associated proxy already has the specified read-only/modifiable setting, then this method does nothing. Parameters readOnly:boolean if true, the associated proxy is made read-only; if false, the associated proxy is made modifiable. Exceptions TransientObjectException: if the proxy is not association with a session SessionException: if the proxy is associated with a sesssion that is closed See Also `org.hibernate.Session#setReadOnly(Object entityOrProxy, boolean readOnly)`

public void setReadOnly(boolean readOnly)

Set an associated modifiable proxy to read-only mode, or a read-only proxy to modifiable mode. If the proxy is currently initialized, its implementation will be set to the same mode; otherwise, when the proxy is initialized, its implementation will have the same read-only/ modifiable setting as the proxy. In read-only mode, no snapshot is maintained and the instance is never dirty checked. If the associated proxy already has the specified read-only/modifiable setting, then this method does nothing.

Parameters

readOnly:boolean: if true, the associated proxy is made read-only; if false, the associated proxy is made modifiable.

Exceptions

TransientObjectException:: if the proxy is not association with a session
SessionException:: if the proxy is associated with a sesssion that is closed

setSession	back to summary
public void setSession(SessionImplementor session) throws HibernateException Associate the proxy with the given session. Care should be given to make certain that the proxy is added to the session's persistence context as well to maintain the symetry of the association. That must be done seperately as this method simply sets an internal reference. We do also check that if there is already an associated session that the proxy reference was removed from that previous session's persistence contet. Parameters session:SessionImplementor The session Exceptions HibernateException: Indicates that the proxy was still contained in the persistence context of the "previous session".

setSession

back to summary

public void setSession(SessionImplementor session) throws HibernateException

Associate the proxy with the given session.

Care should be given to make certain that the proxy is added to the session's persistence context as well to maintain the symetry of the association. That must be done seperately as this method simply sets an internal reference. We do also check that if there is already an associated session that the proxy reference was removed from that previous session's persistence contet.

Parameters

session:SessionImplementor: The session

Exceptions

HibernateException:: Indicates that the proxy was still contained in the persistence context of the "previous session".

setUnwrap	back to summary
public void setUnwrap(boolean unwrap)

unsetSession back to summary

unsetSession	back to summary
public void unsetSession() 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. Generally speaking this is intended to be called only during `org.hibernate.Session#evict` and `org.hibernate.Session#clear` processing; most other use-cases should call `setSession` instead.

public void unsetSession()

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.

Generally speaking this is intended to be called only during org.hibernate.Session#evict and org.hibernate.Session#clear processing; most other use-cases should call setSession instead.
