WriteOnlyObject

Reports objects that are modified but never queried.

The inspection relies on the method mutation contract, which could be inferred or pre-annotated for some library methods. This inspection does not report collections, maps, and string builders, as these types are reported by other more precise inspections.

Example:

AtomicReference<String> ref = new AtomicReference<>();
  ref.set("hello"); // ref is never used again

Use the Ignore impure constructors option to control whether to process objects created by constructor or method whose purity is not known. Unchecking the option may introduce some false-positives if the object reference is intentionally leaked during the construction.
