Annotation Interface ForceQuickening

@Retention(SOURCE)
@Target(METHOD)
@Repeatable(ForceQuickening.Repeat.class)
public @interface ForceQuickening

Forces quickening for an Operation specialization. To quicken a combination of specializations, use the same name. If no name is specified then only the annotated specialization is quickened. It is possible to specify multiple quickenings per specialization (e.g., if a specialization is quickened individually and in a group of specializations). For example, the following code declares two quickenings: one that supports only ints (the plain @ForceQuickening on doInts), and another that supports both ints and doubles (@ForceQuickening("primitives")):

 @Operation
 public static final class Add {
     @Specialization
     @ForceQuickening
     @ForceQuickening("primitives")
     public static int doInts(int lhs, int rhs) {
         return lhs + rhs;
     }

     @Specialization
     @ForceQuickening("primitives")
     public static double doDoubles(double lhs, double rhs) {
         return lhs + rhs;
     }

     @Specialization
     @TruffleBoundary
     public static String doStrings(String lhs, String rhs) {
         return lhs + rhs;
     }
 }

value

String value

The name of the quickening group. If nonempty, all specializations annotated with the same value will be included in a quickened instruction together. By default, this value is empty, which signifies that a specialization should have its own quickened instruction.
