Method decodeInterface

pkg/state/decode.go:470–492

decodeInterface decodes an interface value.

// decodeInterface decodes an interface value.
func (ds *decodeState) decodeInterface(ods *objectDecodeState, obj reflect.Value, encoded *wire.Interface) {
	if _, ok := encoded.Type.(wire.TypeSpecNil); ok {
		// Special case; the nil object. Just decode directly, which
		// will read nil from the wire (if encoded correctly).
		ds.decodeObject(ods, obj, encoded.Value)
		return
	}

	// We now need to resolve the actual type.
	typ := ds.findType(encoded.Type)

	// We need to imbue type information here, then we can proceed to
	// decode normally. In order to avoid issues with setting value-types,
	// we create a new non-interface version of this object. We will then
	// set the interface object to be equal to whatever we decode.
	origObj := obj
	obj = reflect.New(typ).Elem()
	defer origObj.Set(obj)

	// With the object now having sufficient type information to actually
	// have Set called on it, we can proceed to decode the value.
