is a sealed class an abstract class?

[gildor]

not necessary, it may be abstract

[gildor]

Or you mean in bytecode?

[gildor]

In bytecode it’s always abstract

[rrader]

in bytecode

[rrader]

What is the reason?

[tseisel]

It's by definition : a sealed class is a special kind of abstract class with a restricted inheritance hierarchy.

[gildor]

Yes

[gildor]

so you cannot instantiate it

[Shawn]

do we have like commonly-accepted terms to refer to both a sealed class declaration and classes that inherit from them?

[Shawn]

the naming gets a little confusing there lol

[gildor]

I'm personally just call it sealed class

[gildor]

Same way as enum class

[Shawn]

but then what do you call members of a sealed class?

[Shawn]

or, rather, inheriting members of a sealed class hierarchy

[paulex]
