Etymology

Log[Message] Filter.

Synopsis

The LogFilter class is used by the various log sink classes, typically accessed through LogSink , to decide whether a particular LogMessage should be accepted or rejected.

Simple filtering is based on the messages priority. In particular, you typically will choose to only pass messages greater than or equal to NORMAL in priority, but you might choose DEBUGGING to see all messages, or SEVERE to only see messages that report serious problems.

Example

Suppose we wanted to change the global sink so that it prints all messages, including debugging messages:

    LogFilter all(LogMessage::DEBUGGING);
    LogSink::globalSink().filter(all);

Constructor & Destructor Documentation

casa::LogFilter::LogFilter ( LogMessage::Priority lowest = LogMessage::NORMAL )

Construct a filter with the LOWEST priority that you want passed.

Thus DEBUGGING passes everything. Note that it is not possible to block SEVERE level messages, although you can use a NullLogSink which will have this effect.

casa::LogFilter::LogFilter ( const LogFilter & other )

Copy other to this.

virtual casa::LogFilter::~LogFilter ( ) [virtual]

Member Function Documentation

virtual LogFilter* casa::LogFilter::clone ( ) const [virtual]

Clone the object.

Implements casa::LogFilterInterface.

LogMessage::Priority casa::LogFilter::lowestPriority ( ) const [inline]

Return the lowest priority which will pass this filter.

LogFilter& casa::LogFilter::operator= ( const LogFilter & other )

virtual Bool casa::LogFilter::pass ( const LogMessage & message ) const [virtual]

Return True if message passes this filter.

Implements casa::LogFilterInterface.
