Class CommonResourceSupertypeScanner

java.lang.Object

ca.uhn.fhir.rest.server.CommonResourceSupertypeScanner

public class CommonResourceSupertypeScanner
extends Object

 When populating the StructureDefinition links in a capability statement,
 it can be useful to know the lowest common superclass for the profiles in use for a given resource name.
 This class finds this superclass, by incrementally computing the greatest common sequence of ancestor classes in the class hierarchies of registered resources.
 For instance, given the following classes
 MyPatient extends Patient
 MyPatient2 extends MyPatient
 MyPatient3 extends MyPatient
 MyPatient4 extends MyPatient3
 this class will find the common ancestor sequence "IBaseResource -> Patient -> MyPatient". MyPatient is the lowest common superclass in this hierarchy.
