Port java code

@Garry wrote (on that other place)

I’m trying to port this conditional from Java:

if (this.getClass().isInstance(someObject) || someObject().isInstance(this)) {
 // Some code
}

In essence, I need determine if Self is a descendant of someObject 's type or if someObject 's type is a descendant of Self 's type.

Is this possible with introspection? If so, can anyone suggest how?

yes

this is java is about like self in Xojo
so that code amounts to
is self an instance of someobject OR is someobject an instance of self
(as you said)

Private Sub Untitled(selfObject as Object, someObject as Object)
  Dim selfTypeInfo As Introspection.TypeInfo = Introspection.GetType( selfObject )
  Dim someobjectTypeInfo As Introspection.TypeInfo = Introspection.GetType( someobject )
  
  If selfTypeInfo.IsSubclassOf(someobjectTypeInfo) Then
    // selfObject is a subclass or instance of of some other 
    Break
  Elseif  someobjectTypeInfo.IsSubclassOf(selfTypeInfo) Then
    // some other is a subclass or instance of selfObject
    break
  End If
  
End Sub
