JsonNodeOptionalInt

SUGGESTION

Simplification

Suppression

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

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!Jackson3Rules\$JsonNodeOptionalInt).* as compiler argument.

Samples

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

   return ImmutableSet.of(
-      NullNode.getInstance().get(1).asOptional(),
-      NullNode.getInstance().path(2).asOptional(),
