Detailed Description

A PlotLogger is used to log messages to an underlying CASA log object, as well as provide access to different logging functionality like measurements.

PlotLogger is associated with a single Plotter object and should be used by all children of that Plotter (canvases, plot items, etc.) to report their behavior if the proper flag is turned on. The logger can also filter out messages by priority. Therefore a message must BOTH have its event type flag turned on, AND meet the priority minimum in order to be posted to the log. The exception to this is for the MSG_* event types, which are logged as long as they meet the filtered priority requirement. The actual log can either be the global sink, or can be set to a file.

Constructor & Destructor Documentation

casa::PlotLogger::PlotLogger	(	Plotter *	plotter,
		int	filterEventFlags = `NO_EVENTS`,
		LogMessage::Priority	filterMinPriority = `LogMessage::DEBUGGING`
	)

Non-Static //.

Constructor which takes the Plotter this logger is associated with. The global log sink is used, and the minimum priority filter is set.

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

Destructor.

Member Function Documentation

static vector<int> casa::PlotLogger::ALL_EVENTS ( ) [static]

All events as a vector.

static int casa::PlotLogger::ALL_EVENTS_FLAG ( ) [static]

All events as a flag.

static void casa::PlotLogger::disableGlobalSink ( ) [static]

Disables the global sink until enableGlobalSink() is called.

Can be used when something posts undesirably to both the local and global logs.

static void casa::PlotLogger::enableGlobalSink ( ) [static]

Re-enables the global sink.

See disableGlobalSink().

static String casa::PlotLogger::EVENT ( int type ) [static]

Converts between an event type and its name.

static int casa::PlotLogger::EVENT ( const String & name ) [static]

static vector<String> casa::PlotLogger::EVENT_NAMES ( ) [static]

Returns all the event names.

static LogMessage::Priority casa::PlotLogger::EVENT_PRIORITY ( int event ) [static]

Gets/Sets the message priority for the given log event.

Uses a default if the event has not been set.

bool casa::PlotLogger::filterEventFlag ( int flag ) const

Gets/Sets the log filter event flag for a single event type.

int casa::PlotLogger::filterEventFlags ( ) const

Gets/Sets the log filter event flag(s).

The flag should be a bitwise-or of one or more values in PlotLogger events and any extended event types.

LogMessage::Priority casa::PlotLogger::filterMinPriority ( ) const

Filtering Methods //.

Gets/Sets the log filter priority level.

static int casa::PlotLogger::FLAG_FROM_EVENTS ( const vector< int > & events ) [static]

Returns an event flag from the given vector.

static int casa::PlotLogger::FLAG_FROM_EVENTS ( const vector< String > & names ) [static]

static int casa::PlotLogger::FLAG_FROM_PRIORITY ( LogMessage::Priority minPriority ) [static]

Returns an event flag for all events that meet the given minimum priority.

LogSinkInterface* casa::PlotLogger::localSinkCopy ( ) const

Gets a copy of the log sink interface, IF it is not the global.

PlotLogLocate casa::PlotLogger::locate	(	PlotCanvas *	canvas,
		const PlotRegion &	region,
		int	eventType = `MSG_INFO`,
		bool	postLocateMessage = `true`
	)

Locate Methods //.

Calls locate on the given canvas and returns the result as a message that will also be posted if postLocateMessage is true.

PlotLogMessage casa::PlotLogger::markMeasurement	(	const String &	origin1,
		const String &	origin2,
		int	eventType = `PlotLogMessage::DEFAULT_EVENT_TYPE`,
		bool	postStartMessage = `true`
	)

Measurement Methods //.

Marks the logger to begin a time/memory measurement. Measurement marks can be recursive. Returns a generic message saying that measurement has begun, which will be also posted to the log if postStartMessage is true.

void casa::PlotLogger::postMessage ( const PlotLogMessage & message )

Message Methods //.

Posts the given message to the underlying log sink.

void casa::PlotLogger::postMessage	(	const String &	origin1,
		const String &	origin2,
		const String &	message,
		int	eventType = `PlotLogMessage::DEFAULT_EVENT_TYPE`
	)
