virtual ~DfcDbManager()
The d'tor.
CorBool connect( const RWCString& aServer = "" )
DfcDb open( const RWCString& aName )
CorStream open( const RWCString& aName, CorStream::StreamFlow aState )
CorBool isValid()
Query if the database is valid (connection OK, etc).
This function returns corTRUE if the database is valid.
static RWCString getHostname()
Query the hostname currently working on.
This function returns the string representation of the hostname.
virtual RWCString getDbRoot()
Query the database root directory.
This function returns the string representation a directory.
DfcDbManager( const DfcDbManager& aRef )
DfcDbManager& operator=( const DfcDbManager& aRef )
static RWCString setDbRoot()
Query the root directory of all local databases. This is cross checked
against the value of an environment variable. If that is not set, then
it defaults to /dataflow.
This function returns the string representation of the root directory.
static RWCString setHostname()
Set the hostname currently working on.
void close()
static RWCString mDfcDbRoot
Close the connection to a database again.
