Detailed Description

Tries a primary contour extractor and falls back to another extractor on failure.

The wrapper is intended to make contour production more robust when a fast or preferred extraction method can occasionally fail. The fallback is used when the primary extractor throws an exception or returns a contour marked as unsuccessful.

Constructor & Destructor Documentation

WithFallback()

WithFallback::WithFallback ( std::shared_ptr< IContourExtractor >  primary, std::shared_ptr< IContourExtractor >  fallback  )

inline

Constructs a fallback contour extractor wrapper.

Parameters

primary	Extractor attempted first.
fallback	Extractor used if the primary fails or returns an unsuccessful contour.

Member Function Documentation

extract()

Contour WithFallback::extract ( const ScalarField2D &  field, const ContourRequest &  cr  )

inlineoverridevirtual

Extracts a contour using the primary extractor, then fallback if needed.

Parameters

field	Scalar field from which to extract the contour.
cr	Contour extraction request.

Returns

Contour produced by the primary extractor when successful, otherwise by the fallback extractor.

Exceptions

std::exception

propagated from the fallback extractor if fallback extraction also fails.

Implements IContourExtractor.
