class LogStream

Library: Foundation
Package: Logging
Header: Poco/LogStream.h

Description

This class implements an ostream interface to a Logger.

The stream's buffer appends all characters written to it to a string. As soon as a CR or LF (std::endl) is written, the string is sent to the Logger, with the current priority.

Usage example:

LogStream ls(someLogger);
ls << "Some informational message" << std::endl;
ls.error() << "Some error message" << std::endl;
