Annotation Type Constraint

  • @Repeatable(Constraints.class)
@Target(TYPE)
@Retention(RUNTIME)
public @interface Constraint
    An annotation interface that represents a formal constraint (invariant)

    Constraints can be computationally evaluated using a FHIRPath engine or an instance of ConstraintValidator.

      A description used in messages identifying that the constraint has been violated
      java.lang.String expression
      A FHIRPath expression that must evaluate to true when run on the validation target Element or Resource
      java.lang.String id
      Identifies the constraint uniquely amongst all the constraints in the context
      java.lang.String level
      The severity of the constraint
      java.lang.String location
      The location (path) of the validation target Element or Resource
      java.lang.String source
      The original source of the constraint
