Inspectopedia Help

Serializable non-'static' inner class with non-Serializable outer class

Reports non-static inner classes that implement Serializable and are declared inside a class that doesn't implement Serializable.

Such classes are unlikely to serialize correctly due to implicit references to the outer class.

Example:

class A { class Main implements Serializable { } }

Use the following options to configure the inspection:

  • List classes whose inheritors should not be reported by this inspection. This is meant for classes that inherit Serializable from a superclass but are not intended for serialization.

  • Whether to ignore Serializable anonymous classes.
