24 Class
25  Foam::messageStream
26 
27 Description
28  Class to handle messaging in a simple, consistent stream-based
29  manner.
30 
31  The messageStream class is globaly instantiated with a title string a
32  given severity, which controls the program termination, and a number of
33  errors before termination. Errors, messages and other data are piped to
34  the messageStream class in the standard manner.
35 
36 Usage
37  \code
38  messageStream
39  << "message1" << "message2" << FoamDataType << endl;
40  \endcode
