MultimapKeySet

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("MultimapKeySet") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!MultimapRules\$MultimapKeySet).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 Set<String> testMultimapKeySet() {
-    return ImmutableSetMultimap.of("foo", "bar").asMap().keySet();
+    return ImmutableSetMultimap.of("foo", "bar").keySet();
   }
