resolveConstant
List<Base> resolveConstant(Object appContext, String name, boolean beforeContext) throws org.hl7.fhir.exceptions.PathEngineException A constant reference - e.g. a reference to a name that must be resolved in context. The % will be removed from the constant name before this is invoked. This will also be called if the host invokes the FluentPath engine with a context of null- Parameters:
appContext
- - content passed into the fluent path enginename
- - name reference to resolvebeforeContext
- - whether this is being called before the name is resolved locally, or not- Returns:
- the value of the reference (or null, if it's not valid, though can throw an exception if desired)
- Throws:
org.hl7.fhir.exceptions.PathEngineException
-
resolveConstantType
TypeDetails resolveConstantType(Object appContext, String name) throws org.hl7.fhir.exceptions.PathEngineException - Throws:
org.hl7.fhir.exceptions.PathEngineException

resolveReference
Base resolveReference(Object appContext, String url, Base refContext) throws org.hl7.fhir.exceptions.FHIRException Implementation of resolve() function. Passed a string, return matching resource, if one is known - else null- Parameters:
