fetchCodeSystem

public CodeSystem fetchCodeSystem(String theSystem)

Description copied from interface: IWorkerContext

Find an identified resource. The most common use of this is to access the the standard conformance resources that are part of the standard - structure definitions, value sets, concept maps, etc. Also, the narrative generator uses this, and may access any kind of resource The URI is called speculatively for things that might exist, so not finding a matching resouce, return null, not an error The URI can have one of 3 formats: - a full URL e.g. http://acme.org/fhir/ValueSet/[id] - a relative URL e.g. ValueSet/[id] - a logical id e.g. [id] It's an error if the second form doesn't agree with class_. It's an error if class_ is null for the last form
