	This default constructor is called implicitly from the constructor of user-derived classes, even if, for instance, Gtk::Button calls a different ObjectBase constructor.

	A derived constructor always overrides this choice.

	ObjectBase (const std::type_info &custom_type_info)

Detailed Description

A Permission that doesn't change value.

SimplePermission is a trivial implementation of Permission that represents a permission that is either always or never allowed. The value is given at construction and doesn't change.

Calling Permission::acquire() or Permission::release() will result in errors.
