Detailed Description

Message handler class.

The message handler is a static class which handles messages and errors. It has 3 properties:

• the output stream: to which messages will be directed (default stderr)
• message level: messages with a level >= this will be output (default 5)
• fatal level: messages with a level >= this will be fatal (default 9)

Levels may be in the range 1-9. They are priorotised as follows:

• 1-4 messages, never fatal
• 5-8 warning, may be fatal
• 9: always fatal. The fatal level must be greater than or equal to the message level, and greater than or equal to 5.

A message is any object which implements the following methods:

    const std::string& text() const;
    int level() const;

The level method may be static. Messages are usually derived from Message_base.
