Detailed Description

we are reading a single message / Transaction from the stream. We need to read all of it or roll back.

Constructor & Destructor Documentation

cStreamTransaction()

Gray::cStreamTransaction::cStreamTransaction ( cStreamInput *  pInp )

inline

~cStreamTransaction()

Gray::cStreamTransaction::~cStreamTransaction ( )

inline

if we didn't say it was a success, do a rollback on destruct.

Member Function Documentation

isTransactionActive()

bool Gray::cStreamTransaction::isTransactionActive ( ) const

inline

Was SetTransactionComplete called ?

SetTransactionComplete()

void Gray::cStreamTransaction::SetTransactionComplete ( )

inline

Success. we got what we wanted. no rollback.

SetTransactionCompleteN()

void Gray::cStreamTransaction::SetTransactionCompleteN ( size_t  nSize )

inline

SetTransactionFailed()

void Gray::cStreamTransaction::SetTransactionFailed ( )

inline

The stream broke in some way. e.g. socket close. assume connection is broken. no rollback.

SetTransactionRollback()

void Gray::cStreamTransaction::SetTransactionRollback ( )

inline

default behavior if closed without calling SetTransactionComplete() or SetTransactionFailed(). if we didn't say it was a success, do a rollback on destruct.

TransactionRollback()

HRESULT Gray::cStreamTransaction::TransactionRollback ( )
