Create a new instance of this class.

Parameters:

rep - repository

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(RepositoryImpl rep,
                        Subject subject,
                        WorkspaceConfig wspConfig)

                        RepositoryException

Create a new instance of this class.

Parameters:

rep - repository

subject - authenticated subject

wspConfig - workspace configuration

Throws:

RepositoryException - if another error occurs

Method Detail

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()
                          throws XAException

Specified by:

getTransactionTimeout in interface XAResource

Throws:

XAException

setTransactionTimeout

public boolean setTransactionTimeout(int seconds)
                              throws XAException

Specified by:

setTransactionTimeout in interface XAResource

Throws:

XAException

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

Specified by:

end in interface XAResource

Throws:

XAException

prepare

public int prepare(Xid xid)
            throws XAException

Specified by:

prepare in interface XAResource

Throws:

XAException

rollback

public void rollback(Xid xid)
              throws XAException

Specified by:

rollback in interface XAResource

Throws:

XAException

commit

public void commit(Xid xid,
                   boolean onePhase)

Throws:

XAException

              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

dispatch

protected void dispatch(EventStateCollection events)

If we are currently associated with a transaction, the dispatch operation will be postponed until commit.

Overrides:

dispatch in class SessionImpl

Parameters:

events - events to dispatch as result of a successful save operation
