## Constructor & Destructor Documentation

### log4tango::LoggerStream::LoggerStream (Logger & logger, Level::Value level, bool filter = `true`)

Construct a **LoggerStream** for given **Logger** with given level.

**Parameters**

*logger* The logger this stream will send log messages to. \
 *level* The level the log messages will get or Level::NOTSET to silently discard any streamed in messages. \
 *filter* The filter flag

### log4tango::LoggerStream::~LoggerStream ()

Destructor for **LoggerStream**&)

## Member Function Documentation
