Prerequisite

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

Definition at line 80 of file StreamLogSink.h.

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.

StreamLogSink& casacore::StreamLogSink::operator= ( const StreamLogSink other)
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&).

Implements casacore::LogSinkInterface.
