This PR completely decouples filtering and mapping from both
PorterandImportSpecificationusing the newTransformerinterface. Filtering support is still provided with the newFilterTransformersince it is lightweight and often required whilst mapping has been moved to a separate project, MappingTransformer, which can be required as needed.The
Transformerinterface represents post-import data transformation operations and can be implemented by any library wishing to plug in to Porter to provide such transformations. For example, this interface could be used for the proposed hydration and/or validation features in future without requiring any modifications to Porter.Transformerinterface.Transformersupport toPorter::importandImportSpecification.PorterintoFilterTransformer.PorterandImportSpecification.
