Constructor Detail

XASessionImpl

protected XASessionImpl(RepositoryContext repositoryContext,
                        AuthContext loginContext,
                        WorkspaceConfig wspConfig)
                 throws AccessDeniedException,
                        RepositoryException

Create a new instance of this class.

Parameters:

repositoryContext - repository context

loginContext - login context containing authenticated subject

wspConfig - workspace configuration

Throws:

AccessDeniedException - if the subject of the given login context is not granted access to the specified workspace

RepositoryException - if another error occurs

XASessionImpl

protected XASessionImpl(RepositoryContext repositoryContext,
                        Subject subject,
                        WorkspaceConfig wspConfig)
                 throws AccessDeniedException,
                        RepositoryException

Create a new instance of this class.

Parameters:

repositoryContext - repository context

subject - authenticated subject

wspConfig - workspace configuration

Throws:

AccessDeniedException - if the given subject is not granted access to the specified workspace

RepositoryException - if another error occurs

Method Detail

createVersionManager

protected InternalVersionManager createVersionManager()
                                               throws RepositoryException

Create the version manager. If we are not using XA, we may safely use the repository version manager.

Overrides:

createVersionManager in class SessionImpl

Returns:

version manager

Throws:

RepositoryException

getXAResource

public XAResource getXAResource()

Retrieves an XAResource object that the transaction manager will use to manage this XASession object's participation in a distributed transaction.

Specified by:

getXAResource in interface XASession

Returns:

the XAResource object.

getTransactionTimeout

public int getTransactionTimeout()

Specified by:

getTransactionTimeout in interface XAResource

setTransactionTimeout

public boolean setTransactionTimeout(int seconds)

Specified by:

setTransactionTimeout in interface XAResource

isSameRM

public boolean isSameRM(XAResource xares)
                 throws XAException

Two resources belong to the same resource manager if both connections (i.e. sessions) have the same credentials.

Specified by:

isSameRM in interface XAResource

Throws:

XAException

start

public void start(Xid xid,
                  int flags)
           throws XAException

If TMNOFLAGS is specified, we create a new transaction context and associate it with this resource. If TMJOIN is specified, this resource should use the same transaction context as another, already known transaction. If TMRESUME is specified, we should resume work on a transaction context that was suspended earlier. All other flags generate an XAException of type XAER_INVAL

Specified by:

start in interface XAResource

Throws:

XAException

end

public void end(Xid xid,
                int flags)
         throws XAException

If TMSUCCESS is specified, we disassociate this session from the transaction specified. If TMFAIL is specified, we disassociate this session from the transaction specified and mark the transaction rollback only. If TMSUSPEND is specified, we disassociate this session from the transaction specified. All other flags generate an XAException of type XAER_INVAL

It is legal for a transaction association to be suspended and then ended (either with TMSUCCESS or TMFAIL) without having been resumed again.

Specified by:

end in interface XAResource

Throws:

XAException

prepare

public int prepare(Xid xid)
            throws XAException

Specified by:

prepare in interface XAResource

Throws:

XAException

commit

public void commit(Xid xid,
                   boolean onePhase)
            throws XAException

Specified by:

commit in interface XAResource

Throws:

XAException

rollback

public void rollback(Xid xid)
              throws XAException

Specified by:

rollback in interface XAResource

Throws:

XAException

recover

public Xid[] recover(int flags)
              throws XAException

No recovery support yet.

Specified by:

recover in interface XAResource

Throws:

XAException

forget

public void forget(Xid xid)
            throws XAException

No recovery support yet.

Specified by:

forget in interface XAResource

Throws:

XAException

associate

public void associate(TransactionContext tx)

Associate this session with a global transaction. Internally, set the transaction containing all transaction-local objects to be used when performing item retrieval and store.

logout

public void logout()

Invalidates this session and releases all associated resources.

Specified by:

logout in interface Session

Overrides:

logout in class SessionImpl
