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;

LogStream
LogStream(
Logger & logger,
Message::Priority priority = Message::PRIO_INFORMATION,
std::size_t bufferCapacity = DEFAULT_BUFFER_CAPACITY
);

LogStream
LogStream(
const std::string & loggerName,
Message::Priority priority = Message::PRIO_INFORMATION,
std::size_t bufferCapacity = DEFAULT_BUFFER_CAPACITY
);
Creates the LogStream, using the logger identified by loggerName, and sets the priority.
Destructor
