Why is this an issue?
The abstract modifier in a class declaration is
used to indicate that a class is intended only to be a base class of other classes, not instantiated on its own.
Since abstract classes cannot be instantiated, there is no need for public or internal constructors. If
there is basic initialization logic that should run when an extending class instance is created, you can add it in a private,
private protected or protected constructor.
How to fix it
Restrict the constructor visibility to the minimum: private, private protected or protected, depending on
the usage.
Code examples
Noncompliant code example
abstract class Base
{
public Base() // Noncompliant: should be private, private protected or protected.
{
//...
}
}
Compliant solution
abstract class Base
{
protected Base()
{
//...
}
}
