3.11. Run-Time Type Information

Since Vala classes are registered at runtime and each instance carries its type information you can dynamically check the type of an object with the is operator:

bool b = object is SomeTypeName;

You can get the type information of Object instances with the get_type() method:

Type type = object.get_type();
stdout.printf("%s\n", type.name());

With the typeof() operator you can get the type information of a type directly. From this type information you can later create new instances with Object.new():

Type type = typeof(Foo);
Foo foo = (Foo) Object.new(type);

Which constructor will be called? It's the construct {} block that will be described in the section about gobject-style construction.
