Methods in org.hl7.fhir.r4.fhirpath with parameters of type ExpressionNode

Modifier and Type	Method	Description
TypeDetails	FHIRPathEngine.check(Object appContext, String resourceType, String context, ExpressionNode expr)	check that paths referred to in the ExpressionNode are valid xPathStartsWithValueRef is a hack work around for the fact that FHIR Path sometimes needs a different starting point than the xpath returns a list of the possible types that might be returned by executing the ExpressionNode against a particular context
