For instances, instanceof is applied. For classes, isAssignableFrom is applied.
You can always check by looking at isCase.
assert String.isCase('foo')
assert !Class.isCase(String)
assert CharSequence.isCase(String)
assert Object.isCase(Class)
assert switch(String) {
case Class -> false
case CharSequence -> true
}
