Class TerminologyCache

java.lang.Object

org.hl7.fhir.r4.context.TerminologyCache

public class TerminologyCache
extends Object

This implements a two level cache. - a temporary cache for remmbering previous local operations - a persistent cache for rembering tx server operations the cache is a series of pairs: a map, and a list. the map is the loaded cache, the list is the persiistent cache, carefully maintained in order for version control consistency
