Detailed Documentation

This class implements a streambuf interface to a Logger.

The streambuf 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 set priority.

Construction

LogStreamBuf(
    Logger& logger,
    Message::Priority priority
    )

Creates the LogStream.

Methods

void
setPriority(Message::Priority priority)

Sets the priority for log messages.

Message::Priority
getPriority() const

Returns the priority for log messages.

Logger&
logger() const

Returns a reference to the Logger.
