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();
   }

MultimapSize

SUGGESTION

Simplification

Suppression

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

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

Samples

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

 int testMultimapSize() {
-    return ImmutableSetMultimap.of().values().size();
+    return ImmutableSetMultimap.of().size();
   }

MultimapGet

SUGGESTION

Suppression

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

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

-        ImmutableSetMultimap.of(1, 2).asMap().get(1),
-        Multimaps.asMap((Multimap<Integer, Integer>) ImmutableSetMultimap.of(1, 2)).get(1));
+        ImmutableSetMultimap.of(1, 2).get(1),
+        ((Multimap<Integer, Integer>) ImmutableSetMultimap.of(1, 2)).get(1));
