Prerequisite

LogSinkInterface
ostream

Etymology

"Stream" from the family of standard C++ I/O classes.

Synopsis

StreamLogSink is a straightforward LogSinkInterface which sends its messages to an ostream (typically cerr) which it is given at construction time. It is not intended to be used directly, rather it should be used through LogSink .

Example

See (see (file="Logging.h"))Logging.h .

Motivation

Writing to standard output or error will be a common way of displaying log messages.

To Do

Nothing known.

Constructor & Destructor Documentation

casa::StreamLogSink::StreamLogSink	(	ostream *	theStream = `0`,
		bool	deleteStream = `false`
	)		`[explicit]`

Defaults to cerr if no stream is supplied.

The caller is responsible for ensuring that the supplied ostream ostream lives at least as long as this sink. If not filter is supplied, NORMAL is used.
