Detailed Description

Basic class to optionally replace vtkAlgorithm progress functionality.

When the basic functionality in vtkAlgorithm that reports progress is not enough, a subclass of vtkProgressObserver can be used to provide custom functionality. The main use case for this is when an algorithm's RequestData() is called from multiple threads in parallel - the basic functionality in vtkAlgorithm is not thread safe. vtkSMPProgressObserver can handle this situation by routing progress from each thread to a thread local vtkProgressObserver, which will invoke events separately for each thread.

Events:

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 vtkObject.

Reimplemented in vtkSMPProgressObserver.

(

)

const

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

virtual

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.

Reimplemented in vtkSMPProgressObserver.

virtual void vtkProgressObserver::UpdateProgress ( double  amount )

virtual

The default behavior is to update the Progress data member and invoke a ProgressEvent. This is designed to be overwritten.

Reimplemented in vtkSMPProgressObserver.

virtual double vtkProgressObserver::GetProgress ( )

virtual

Returns the progress reported by the algorithm.
