- * SECTION:object.h
- * @title:Base Object Type System
- * @short_description: interfaces for creating new types and objects
- *
- * The QEMU Object Model provides a framework for registering user creatable
- * types and instantiating objects from those types.  QOM provides the following
- * features:
- *
- *  - System for dynamically registering types
- *  - Support for single-inheritance of types
- *  - Multiple inheritance of stateless interfaces
- *
- * <example>
- *   <title>Creating a minimal type</title>
- *   <programlisting>
- * #include "qdev.h"
- *
- * #define TYPE_MY_DEVICE "my-device"
- *
- * // No new virtual functions: we can reuse the typedef for the
- * // superclass.
- * typedef DeviceClass MyDeviceClass;
- * typedef struct MyDevice
- * {
- *     DeviceState parent;
- *
- *     int reg0, reg1, reg2;
- * } MyDevice;
- *
- * static const TypeInfo my_device_info = {
- *     .name = TYPE_MY_DEVICE,
- *     .parent = TYPE_DEVICE,
- *     .instance_size = sizeof(MyDevice),
- * };
- *
- * static void my_device_register_types(void)
- * {
- *     type_register_static(&my_device_info);
- * }
- *
- * type_init(my_device_register_types)
- *   </programlisting>
- * </example>
- *
- * In the above example, we create a simple type that is described by #TypeInfo.
- * #TypeInfo describes information about the type including what it inherits
- * from, the instance and class size, and constructor/destructor hooks.
- *
- * Every type has an #ObjectClass associated with it.  #ObjectClass derivatives
- * are instantiated dynamically but there is only ever one instance for any
- * given type.  The #ObjectClass typically holds a table of function pointers
- * for the virtual methods implemented by this type.
- *
- * Using object_new(), a new #Object derivative will be instantiated.  You can
- * cast an #Object to a subclass (or base-class) type using
- * object_dynamic_cast().  You typically want to define macro wrappers around
- * OBJECT_CHECK() and OBJECT_CLASS_CHECK() to make it easier to convert to a
- * specific type:
- *
- * <example>
- *   <title>Typecasting macros</title>
- *   <programlisting>
- *    #define MY_DEVICE_GET_CLASS(obj) \
- *       OBJECT_GET_CLASS(MyDeviceClass, obj, TYPE_MY_DEVICE)
- *    #define MY_DEVICE_CLASS(klass) \
- *       OBJECT_CLASS_CHECK(MyDeviceClass, klass, TYPE_MY_DEVICE)
- *    #define MY_DEVICE(obj) \
- *       OBJECT_CHECK(MyDevice, obj, TYPE_MY_DEVICE)
- *   </programlisting>
- * </example>
- *
- * # Class Initialization #
- *
- * Before an object is initialized, the class for the object must be
- * initialized.  There is only one class object for all instance objects
- * that is created lazily.
- *
- * Classes are initialized by first initializing any parent classes (if
- * necessary).  After the parent class object has initialized, it will be
- * copied into the current class object and any additional storage in the
- * class object is zero filled.
- *
- * The effect of this is that classes automatically inherit any virtual
- * function pointers that the parent class has already initialized.  All
- * other fields will be zero filled.
- *
- * Once all of the parent classes have been initialized, #TypeInfo::class_init
- * is called to let the class being instantiated provide default initialize for
- * its virtual functions.  Here is how the above example might be modified
- * to introduce an overridden virtual function:
- *
- * <example>
- *   <title>Overriding a virtual function</title>
- *   <programlisting>
- * #include "qdev.h"
- *
- * void my_device_class_init(ObjectClass *klass, void *class_data)
- * {
- *     DeviceClass *dc = DEVICE_CLASS(klass);
- *     dc->reset = my_device_reset;
- * }
- *
- * static const TypeInfo my_device_info = {
- *     .name = TYPE_MY_DEVICE,
- *     .parent = TYPE_DEVICE,
- *     .instance_size = sizeof(MyDevice),
- *     .class_init = my_device_class_init,
- * };
- *   </programlisting>
- * </example>
- *
- * Introducing new virtual methods requires a class to define its own
- * struct and to add a .class_size member to the #TypeInfo.  Each method
- * will also have a wrapper function to call it easily:
- *
- * <example>
- *   <title>Defining an abstract class</title>
- *   <programlisting>
- * #include "qdev.h"
- *
- * typedef struct MyDeviceClass
- * {
- *     DeviceClass parent;
- *
- *     void (*frobnicate) (MyDevice *obj);
- * } MyDeviceClass;
- *
- * static const TypeInfo my_device_info = {
- *     .name = TYPE_MY_DEVICE,
- *     .parent = TYPE_DEVICE,
- *     .instance_size = sizeof(MyDevice),
- *     .abstract = true, // or set a default in my_device_class_init
- *     .class_size = sizeof(MyDeviceClass),
- * };
- *
- * void my_device_frobnicate(MyDevice *obj)
- * {
- *     MyDeviceClass *klass = MY_DEVICE_GET_CLASS(obj);
- *
- *     klass->frobnicate(obj);
- * }
- *   </programlisting>
- * </example>
- *
- * # Interfaces #
- *
- * Interfaces allow a limited form of multiple inheritance.  Instances are
- * similar to normal types except for the fact that are only defined by
- * their classes and never carry any state.  You can dynamically cast an object
- * to one of its #Interface types and vice versa.
- *
- * # Methods #
- *
- * A <emphasis>method</emphasis> is a function within the namespace scope of
- * a class. It usually operates on the object instance by passing it as a
- * strongly-typed first argument.
- * If it does not operate on an object instance, it is dubbed
- * <emphasis>class method</emphasis>.
- *
- * Methods cannot be overloaded. That is, the #ObjectClass and method name
- * uniquely identity the function to be called; the signature does not vary
- * except for trailing varargs.
- *
- * Methods are always <emphasis>virtual</emphasis>. Overriding a method in
- * #TypeInfo.class_init of a subclass leads to any user of the class obtained
- * via OBJECT_GET_CLASS() accessing the overridden function.
- * The original function is not automatically invoked. It is the responsibility
- * of the overriding class to determine whether and when to invoke the method
- * being overridden.
- *
- * To invoke the method being overridden, the preferred solution is to store
- * the original value in the overriding class before overriding the method.
- * This corresponds to |[ {super,base}.method(...) ]| in Java and C#
- * respectively; this frees the overriding class from hardcoding its parent
- * class, which someone might choose to change at some point.
- *
- * <example>
- *   <title>Overriding a virtual method</title>
- *   <programlisting>
- * typedef struct MyState MyState;
- *
- * typedef void (*MyDoSomething)(MyState *obj);
- *
- * typedef struct MyClass {
- *     ObjectClass parent_class;
- *
- *     MyDoSomething do_something;
- * } MyClass;
- *
- * static void my_do_something(MyState *obj)
- * {
- *     // do something
- * }
- *
- * static void my_class_init(ObjectClass *oc, void *data)
- * {
- *     MyClass *mc = MY_CLASS(oc);
- *
- *     mc->do_something = my_do_something;
- * }
- *
- * static const TypeInfo my_type_info = {
- *     .name = TYPE_MY,
- *     .parent = TYPE_OBJECT,
- *     .instance_size = sizeof(MyState),
- *     .class_size = sizeof(MyClass),
- *     .class_init = my_class_init,
- * };
- *
- * typedef struct DerivedClass {
- *     MyClass parent_class;
- *
- *     MyDoSomething parent_do_something;
- * } DerivedClass;
- *
- * static void derived_do_something(MyState *obj)
- * {
- *     DerivedClass *dc = DERIVED_GET_CLASS(obj);
- *
- *     // do something here
- *     dc->parent_do_something(obj);
- *     // do something else here
- * }
- *
- * static void derived_class_init(ObjectClass *oc, void *data)
- * {
- *     MyClass *mc = MY_CLASS(oc);
- *     DerivedClass *dc = DERIVED_CLASS(oc);
- *
- *     dc->parent_do_something = mc->do_something;
- *     mc->do_something = derived_do_something;
- * }
- *
- * static const TypeInfo derived_type_info = {
- *     .name = TYPE_DERIVED,
- *     .parent = TYPE_MY,
- *     .class_size = sizeof(DerivedClass),
- *     .class_init = derived_class_init,
- * };
- *   </programlisting>
- * </example>
- *
- * Alternatively, object_class_by_name() can be used to obtain the class and
- * its non-overridden methods for a specific type. This would correspond to
- * |[ MyClass::method(...) ]| in C++.
- *
- * The first example of such a QOM method was #CPUClass.reset,
- * another example is #DeviceClass.realize.
