org.hl7.fhir.common.hapi.validation.validator.FHIRPathResourceGeneratorR4<T>

public class FHIRPathResourceGeneratorR4<T extends org.hl7.fhir.r4.model.Resource>
extends Object

This class can be used to generate resources using FHIRPath expressions. Note that this is an experimental feature and the API is expected to change. Ideally this will be made version independent and moved out of the validation module in a future release.
