Type parameter explicitly extends 'Object'
Reports type parameters and wildcard type arguments that are explicitly declared to extend java.lang.Object
.
Such 'extends' clauses are redundant as java.lang.Object
is a supertype for all classes.
Example:
class ClassA<T extends Object> {}
- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
TypeParameterExplicitlyExtendsObject
If you need to preserve the 'extends Object' clause because of annotations, disable the Ignore when java.lang.Object is annotated option. This might be useful, for example, when you use a nullness analyzer, and the 'extends Object' clause holds a @Nullable
/@NotNull
annotation.
Example:
class MyClass<T extends @NotNull Object> {}
Here you can find the description of settings available for the Type parameter explicitly extends 'Object' inspection, and the reference of their default values.
