Severity: Info

Category: Best Practices

Description

While authorized by the compiler, protected visibility in sealed classes does not make sense as these classes cannot be inherited. Use public or private instead.

Non-Compliant Code Examples

public sealed class MyClass {
    protected int foo;

    protected void myMethod() {
        
    }
}

Compliant Code Examples

public sealed class MyClass {
    private int foo;

    private void myMethod() {
        
    }
}
