Methods

andThen

andThen(after: ValueExtractor): ValueExtractor

Inherited from ValueExtractor.andThen

Returns a composed extractor that first applies this extractor to its input, and then applies the after extractor to the result. If evaluation of either extractor throws an exception, it is relayed to the caller of the composed extractor.

Parameters
- after: ValueExtractor
  
  the extractor to apply after this extractor is applied
Returns ValueExtractor

a composed extractor that first applies this extractor and then applies the after extractor

compose

compose(before: ValueExtractor): ValueExtractor

Inherited from ValueExtractor.compose

Returns a composed extractor that first applies the before extractor to its input, and then applies this extractor to the result. If evaluation of either extractor throws an exception, it is relayed to the caller of the composed extractor.

Parameters
- before: ValueExtractor
  
  the extractor to apply before this extractor is applied
Returns ValueExtractor

a composed extractor that first applies the before extractor and then applies this extractor
