Type


Object Hierarchy:

Object hierarchy for Type

Description:

public struct Type : ulong

A numerical value which represents the unique identifier of a registered type.

Example: Introspection (GType):

public interface Interface : Object {}
public abstract class AbstractGObject : Object, Interface {}

public static int main (string[] args) {
// Output:
// ``AbstractGObject``
// `` is-obj: true``
// `` is-abstr: true``
// `` is-classed: true``
// `` is-derivable: true``
// `` is-derived: true``
// `` is-fund: false``
// `` is-inst: true``
// `` is-iface: false``
// `` is-enum: false``
// `` is-flags: true``
Type type = typeof (AbstractGObject);
print ("%s\n", type.name ());
print (" is-obj: %s\n", type.is_object ().to_string ());
print (" is-abstr: %s\n", type.is_abstract ().to_string ());
print (" is-classed: %s\n", type.is_classed ().to_string ());
print (" is-derivable: %s\n", type.is_derivable ().to_string ());
print (" is-derived: %s\n", type.is_derived ().to_string ());
print (" is-fund: %s\n", type.is_fundamental ().to_string ());
print (" is-inst: %s\n", type.is_instantiatable ().to_string ());
print (" is-iface: %s\n", type.is_interface ().to_string ());
print (" is-enum: %s\n", type.is_enum ().to_string ());
print (" is-flags: %s\n", type.is_object ().to_string ());

// Output:
// `` Children:``
print (" Children:\n");
foreach (unowned Type ch in type.children ()) {
print (" - %s\n", ch.name ());
}

// `` Interfaces:``
// `` - Interface``
print (" Interfaces:\n");
foreach (unowned Type ch in type.interfaces ()) {
print (" - %s\n", ch.name ());
}

// Output:
// `` Parents:``
// `` - GObject``
print (" Parents:\n");
for (Type p = type.parent (); p != 0 ; p = p.parent ()) {
print (" - %s\n", p.name ());
}

return 0;
}
