Function simics::api::base::conf_object::extend_class

pub fn extend_class(cls: *mut ConfClass, ext: *mut ConfClass) -> Result<()>

The function extends the class cls with attributes, interfaces, port objects and port interfaces defined by the extension class ext.

The extension class must be of the type Sim_Class_Kind_Extension and must not define any attributes or interfaces which have already been defined by the class being augmented.

Besides normal object initialization, the init_object method for the extension class, will be called when cls is instantiated. The pointer returned by init_object can be retrieved using SIM_extension_data. The init_object method may return NULL if no private data pointer is needed; this does not signify an error condition for extension classes.

The finalize_instance method defined by the extension class will be called before the finalize_instance method is called for the class being extended.

The SIM_extension_class function is intended to be used to extend a class with generic functionality, common to multiple classes.

Arguments
