Package com.ibm.fhir.path.function

Class MemberOfFunction

java.lang.Object

com.ibm.fhir.path.function.FHIRPathAbstractFunction

com.ibm.fhir.path.function.MemberOfFunction

All Implemented Interfaces:

FHIRPathFunction

public class MemberOfFunction
extends FHIRPathAbstractFunction

Implementation of the 'memberOf' FHIRPath function per: http://hl7.org/fhir/fhirpath.html#functions

This implementation supports an optional second argument (binding strength). The binding strength is used to determine whether or not to add a warning to the evaluation context if the membership check fails.

In addition, if the optional argument is specified, this implementation will successfully validate a Code, Coding, Quantity, String, or Uri element in which the data-absent-reason extension is specified and no value or code+system is specified.
