Detailed Description

Messenger is API class providing general-purpose interface for libraries that may issue text messages without knowledge of how these messages will be further processed.

The messenger contains a sequence of "printers" which can be customized by the application, and dispatches every received message to all the printers.

For convenience, a number of operators << are defined with left argument being Handle(Message_Messenger); thus it can be used with syntax similar to C++ streams. Note that all these operators use trace level Warning.

Constructor & Destructor Documentation

Message_Messenger::Message_Messenger ( )

Empty constructor; initializes by single printer directed to cout. Note: the default messenger is not empty but directed to cout in order to protect against possibility to forget defining printers. If printing to cout is not needed, clear messenger by GetPrinters().Clear()

Message_Messenger::Message_Messenger ( const Handle< Message_Printer > &  thePrinter)

Create messenger with single printer.

Member Function Documentation

Standard_Boolean Message_Messenger::AddPrinter ( const Handle< Message_Printer > &  thePrinter)

Add a printer to the messenger. The printer will be added only if it is not yet in the list. Returns True if printer has been added.

Message_SequenceOfPrinters& Message_Messenger::ChangePrinters ( )

Returns sequence of printers The sequence can be modified.

const Message_SequenceOfPrinters& Message_Messenger::Printers ( ) const

Returns current sequence of printers.

Standard_Boolean Message_Messenger::RemovePrinter ( const Handle< Message_Printer > &  thePrinter)

Removes specified printer from the messenger. Returns True if this printer has been found in the list and removed.

Standard_Integer Message_Messenger::RemovePrinters ( const Handle< Standard_Type > &  theType)

Removes printers of specified type (including derived classes) from the messenger. Returns number of removed printers.

void Message_Messenger::Send ( const Standard_CString  theString,
const Message_Gravity  theGravity = Message_Warning,
const Standard_Boolean  putEndl = Standard_True 
) const

Dispatch a message to all the printers in the list. Three versions of string representations are accepted for convenience, by default all are converted to ExtendedString. The parameter putEndl specifies whether the new line should be started after this message (default) or not (may have sense in some conditions).

void Message_Messenger::Send ( const TCollection_AsciiString theString,
const Message_Gravity  theGravity = Message_Warning,
const Standard_Boolean  putEndl = Standard_True 
) const

See above.

void Message_Messenger::Send ( const TCollection_ExtendedString theString,
const Message_Gravity  theGravity = Message_Warning,
const Standard_Boolean  putEndl = Standard_True 
) const

See above.
