SessionImpl (Hibernate Core Aggregator 3.6.9.Final API)

java.lang.Object
- org.hibernate.impl.AbstractSessionImpl
- - org.hibernate.impl.SessionImpl

All Implemented Interfaces:

java.io.Serializable, LobCreationContext, SessionImplementor, EventSource, JDBCContext.Context, Session, TransactionFactory.Context
```
public final class SessionImpl
extends AbstractSessionImpl
implements EventSource, Session, JDBCContext.Context, LobCreationContext
```
Concrete implementation of a Session, and also the central, organizing component of Hibernate's internal implementation. As such, this class exposes two interfaces; Session itself, to the application, and SessionImplementor, to other components of Hibernate. This class is not threadsafe.

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`afterOperation(boolean success)` Check if there is a Hibernate or JTA transaction in progress and, if there is not, flush if necessary, make sure the connection has been committed (if it is not in autocommit mode) and run the after completion processing
`void`	`afterScrollOperation()`
`void`	`afterTransactionBegin(Transaction tx)` We cannot rely upon this method being called! It is only called if we are using Hibernate Transaction API.
`void`	`afterTransactionCompletion(boolean success, Transaction tx)` Notify the session that the transaction completed, so we no longer own the old locks.
`void`	`applyNonFlushedChanges(NonFlushedChanges nonFlushedChanges)` Apply non-flushed changes from a different session to this session.
`protected boolean`	`autoFlushIfRequired(java.util.Set querySpaces)` detect in-memory changes, determine if the changes are to tables named in the query and, if so, complete execution the flush

    Description copied from interface: Session
    
    Disconnect the Session from the current JDBC connection. If the connection was obtained by Hibernate close it and return it to the connection pool; otherwise, return it to the application.
    This is used by applications which supply JDBC connections to Hibernate and which require long-sessions (or long-conversations)
    Note that disconnect() called on a session where the connection was retrieved by Hibernate through its configured ConnectionProvider has no effect, provided ConnectionReleaseMode.ON_CLOSE is not in effect.

    Description copied from interface: Session
    
    Return the persistent instance of the given entity class with the given identifier, assuming that the instance exists. This method might return a proxied instance that is initialized on-demand, when a non-identifier method is accessed.
    
    You should not use this method to determine if an instance exists (use get() instead). Use this only to retrieve an instance that you assume exists, where non-existence would be an actual error.

    Will entities and proxies that are loaded into this session be made read-only by default? To determine the read-only/modifiable setting for a particular entity or proxy:
    
    Specified by:
    
    isDefaultReadOnly in interface Session
    
    Returns:
    true, loaded entities/proxies will be made read-only by default; false, loaded entities/proxies will be made modifiable by default.
    See Also:
    Session.isReadOnly(Object)
  - setDefaultReadOnly
```
public void setDefaultReadOnly(boolean defaultReadOnly)
```
    Change the default for entities and proxies loaded into this session from modifiable to read-only mode, or from modifiable to read-only mode. Read-only entities are not dirty-checked and snapshots of persistent state are not maintained. Read-only entities can be modified, but changes are not persisted. When a proxy is initialized, the loaded entity will have the same read-only/modifiable setting as the uninitialized proxy has, regardless of the session's current setting. To change the read-only/modifiable setting for a particular entity or proxy that is already in this session:
    
    Specified by:
    
    setDefaultReadOnly in interface Session
    
    Parameters:
    defaultReadOnly - true, the default for loaded entities/proxies is read-only; false, the default for loaded entities/proxies is modifiable
    See Also:
    To override this session's read-only/modifiable setting for entities and proxies loaded by a Query:, Query.setReadOnly(boolean)
  - isReadOnly
```
public boolean isReadOnly(java.lang.Object entityOrProxy)
```
    Description copied from interface: Session
    
    Is the specified entity or proxy read-only? To get the default read-only/modifiable setting used for entities and proxies that are loaded into the session:
    
    Specified by:
    
    isReadOnly in interface Session
    
    Parameters:
    entityOrProxy - an entity or HibernateProxy
    
    Returns:
    true, the entity or proxy is read-only; false, the entity or proxy is modifiable.
    See Also:
    Session.isDefaultReadOnly()
  - setReadOnly
```
public void setReadOnly(java.lang.Object entity,
               boolean readOnly)
```
    Description copied from interface: Session
    
    Set an unmodified persistent object to read-only mode, or a read-only object to modifiable mode. In read-only mode, no snapshot is maintained, the instance is never dirty checked, and changes are not persisted. If the entity or proxy already has the specified read-only/modifiable setting, then this method does nothing. To set the default read-only/modifiable setting used for entities and proxies that are loaded into the session:
    
    Specified by:
    
    setReadOnly in interface Session
    
    Parameters:
    entity - an entity or HibernateProxy
    readOnly - if true, the entity or proxy is made read-only; if false, the entity or proxy is made modifiable.
