Package com.google.errorprone.refaster.annotation

Annotation Type Matches

@Target({PARAMETER,METHOD})
@Retention(SOURCE)
public @interface Matches

Specify an error-prone Matcher to further restrict what expressions are matched by the annotated parameter.

Note: The @Matches annotation should only go on the @BeforeTemplate. For example:

 class SingletonList {
   @BeforeTemplate
   public <E> List<E> before(@Matches(IsNonNullMatcher.class) E e) {
     return Collections.singletonList(e);
   }

   @AfterTemplate
   public <E> List<E> after(E e) {
     return ImmutableList.of(e);
   }
 }
