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 set of methods Send...() returning a string stream buffer is defined for use of stream-like syntax with operator <<

Example:

Messenger->SendFail() << " Unknown fail at line " << aLineNo << " in file " << aFile;

NCollection_UBTree

Definition NCollection_UBTree.hxx:64

The message is sent to messenger on destruction of the stream buffer, call to Flush(), or passing manipulator std::ends, std::endl, or std::flush. Empty messages are not sent except if manipulator is used.
