Detailed Description

Timer support and logging.

vtkTimerLog contains walltime and cputime measurements associated with a given event. These results can be later analyzed when "dumping out" the table.

In addition, vtkTimerLog allows the user to simply get the current time, and to start/stop a simple timer separate from the timing table logging.

static

virtual vtkTypeBool vtkTimerLog::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

void vtkTimerLog::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

static void vtkTimerLog::SetLogging ( int v )

inlinestatic

This flag will turn logging of events off or on.

By default, logging is on.

Record a timing event.

The event is represented by a formatted string.

Write the timing table out to a file.

Calculate some helpful statistics (deltas and percentages) in the process.

static void vtkTimerLog::MarkStartEvent ( const char * EventString )

I want to time events, so I am creating this interface to mark events that have a start and an end.

These events can be, nested. The standard Dumplog ignores the indents.
