Factory for PersistencySvc.

databaseHandle()

virtual std::unique_ptr< IDatabase > pool::PersistencySvc::UserSession::databaseHandle ( const std::string & dbName, DatabaseSpecification::NameType dbNameType )

finaloverridevirtual

Creates and returns a new database handle object.

Implements pool::ISession.

defaultConnectionPolicy()

virtual const DatabaseConnectionPolicy & pool::PersistencySvc::UserSession::defaultConnectionPolicy ( ) const

finaloverridevirtual

Retrieves the default connection policy.

Implements pool::ISession.

disconnectAll()

virtual bool pool::PersistencySvc::UserSession::disconnectAll ( )

finaloverridevirtual

Explicitly disconnects all the databases.

If a transaction is active, then all the changes since the last commit are aborted.

Implements pool::ISession.

fileCatalog()

virtual IFileCatalog & pool::PersistencySvc::UserSession::fileCatalog ( )

finaloverridevirtual

Returns the file catalog in use.

Implements pool::ISession.

globalTransaction()

ITransaction & pool::PersistencySvc::UserSession::globalTransaction

(

)

Returns the global transaction object.

microSessionManager()

MicroSessionManager & pool::PersistencySvc::UserSession::microSessionManager

(

long

technology

)

Returns the technology given a technology type.

operator=()

UserSession & pool::PersistencySvc::UserSession::operator= ( const UserSession & )

delete

readObject()

void * pool::PersistencySvc::UserSession::readObject ( const Token & token, void * object = 0 )

virtual

Retrieves an object from persistent store and return with type information The handle to the reflection class is necessary to later delete the object.

The Guid of the transient class is assumed to be the classID of the token

Parameters

token	[IN] reference to the token for the object
object	[IN] pointer to memory for the object (created if 0)

Returns

void* The data.

In case of failure zero is returned.

Implements pool::IPersistencySvc.

registerForWrite()

Token * pool::PersistencySvc::UserSession::registerForWrite ( const Placement & place, const void * object, const RootType & type )

virtual

registerForWrite registers an object for writing to the persistent medium higher level interactions with the framework are necessary.

Parameters

place	[IN] the placement hint
object	[IN] pointer to transient object which will be written
type	[IN] reflection class description with the layout of transient object

Returns

Token* the token address of the persistent object. I case of failure 0 is returned.

Implements pool::IPersistencySvc.

registry()

setDefaultConnectionPolicy()

virtual void pool::PersistencySvc::UserSession::setDefaultConnectionPolicy ( const DatabaseConnectionPolicy & policy )

finaloverridevirtual

Sets the default policy when databases are opened/connected.

Implements pool::ISession.

setFileCatalog()

void pool::PersistencySvc::UserSession::setFileCatalog

(

IFileCatalog &

catalog

)

Set the file catalog to be used.

technologySpecificAttributes() [1/2]

virtual const ITechnologySpecificAttributes & pool::PersistencySvc::UserSession::technologySpecificAttributes ( long technology ) const

finaloverridevirtual

Returns the object holding the technology specific attributes for a given technology domain.

Implements pool::ISession.
