Constructor Detail

DistributedSession

public DistributedSession(oracle.toplink.internal.remote.RemoteConnection remoteConnection)

Creates a DistributedSession.

Parameters:

remoteConnection - remote session requires a remote connection. This must be accessed remotely from the client through RMI or CORBA.

Method Detail

acquireUnitOfWork

public abstract oracle.toplink.internal.sessions.UnitOfWorkImpl acquireUnitOfWork()

Return a unit of work for this session. The unit of work is an object level transaction that allows a group of changes to be applied as a unit.

Specified by:

acquireUnitOfWork in interface Session

Overrides:

acquireUnitOfWork in class oracle.toplink.internal.sessions.AbstractSession

See Also:

UnitOfWorkImpl

beginTransaction

public void beginTransaction()

Start a transaction on the server. A unit of work should normally be used instead of transactions for the remote session.

Overrides:

beginTransaction in class oracle.toplink.internal.sessions.AbstractSession

See Also:

AbstractSession.isInTransaction()

commitTransaction

public void commitTransaction()

Commit a transaction on the server. A unit of work should normally be used instead of transactions for the remote session.

Overrides:

commitTransaction in class oracle.toplink.internal.sessions.AbstractSession

executeQuery

public java.lang.Object executeQuery(java.lang.String queryName)
                              throws DatabaseException

Execute the pre-defined query by name and return the result. Queries can be pre-defined and named to allow for their reuse. The named query can be defined on the remote session or the server-side session.

Specified by:

executeQuery in interface Session

Overrides:

executeQuery in class oracle.toplink.internal.sessions.AbstractSession

Throws:

DatabaseException

See Also:

AbstractSession.addQuery(String, DatabaseQuery)

executeQuery

public java.lang.Object executeQuery(java.lang.String queryName,
                                     java.lang.Class domainClass)
                              throws DatabaseException

Execute the pre-defined query by name and return the result. Queries can be pre-defined and named to allow for their reuse. The class is the descriptor in which the query was pre-defined. The query is executed on the server-side session.

Specified by:

executeQuery in interface Session

Overrides:

executeQuery in class oracle.toplink.internal.sessions.AbstractSession

Throws:

DatabaseException

See Also:

DescriptorQueryManager.addQuery(String, DatabaseQuery)

executeQuery

public java.lang.Object executeQuery(java.lang.String queryName,
                                     java.lang.Class domainClass,
                                     java.util.Vector argumentValues)
                              throws DatabaseException

Execute the pre-defined query by name and return the result. Queries can be pre-defined and named to allow for their reuse. The class is the descriptor in which the query was pre-defined.

Specified by:

executeQuery in interface Session

Overrides:

executeQuery in class oracle.toplink.internal.sessions.AbstractSession

Throws:

DatabaseException

See Also:

DescriptorQueryManager.addQuery(String, DatabaseQuery)

executeQuery

public java.lang.Object executeQuery(java.lang.String queryName,

                              throws DatabaseException

Execute the pre-defined query by name and return the result. Queries can be pre-defined and named to allow for their reuse.

Specified by:

executeQuery in interface Session

Overrides:

executeQuery in class oracle.toplink.internal.sessions.AbstractSession

Throws:

DatabaseException

See Also:

AbstractSession.addQuery(String, DatabaseQuery)

executeQuery

public abstract java.lang.Object executeQuery(DatabaseQuery query)

Execute the database query.

Specified by:

executeQuery in interface Session

isConnected

public boolean isConnected()

Return if this session is connected to the server.

Specified by:

isConnected in interface Session

Overrides:

isConnected in class oracle.toplink.internal.sessions.AbstractSession

rollbackTransaction

public void rollbackTransaction()

Rollback a transaction on the server. A unit of work should normally be used instead of transactions for the remote session.

Overrides:
