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

casacore::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.

casacore::StreamLogSink::StreamLogSink ( LogMessage::Priority  filter, ostream *  theStream = 0, bool  deleteStream = false  )

explicit

casacore::StreamLogSink::StreamLogSink ( const LogFilterInterface &  filter, ostream *  theStream = 0, bool  deleteStream = false  )

explicit

casacore::StreamLogSink::StreamLogSink

(

const StreamLogSink &

other

)

Make a copy of other.

After copying, both objects will post to the same stream.

virtual Bool casacore::StreamLogSink::postLocally ( const LogMessage &  message )

Write message to the stream if it passes the filter.

Works by calling operator<<(ostream &,const LogMesssage&).
