Guava pseudo-functional call can be converted to Stream API call
Reports usages of Guava pseudo-functional code when Java Stream API is available.
Though Guava Iterable API provides functionality similar to Java Streams API, it's slightly different and may miss some features. Especially, primitive-specialized stream variants like IntStream are more performant than generic variants.
Example:
After the quick-fix is applied:
List<String> transformedIterable = someList.stream().map(someTransformFunction).collect(Collectors.toList());
Note: Code semantics can be changed; for example, Guava's Iterable.transform produces a lazy-evaluated iterable, but the replacement is eager-evaluated.
