Function derefPointer

enterprise/audit/diff.go:234–249

derefPointer deferences a reflect.Value that is a pointer to its underlying value. It dereferences recursively until it finds a non-pointer value. If the pointer is nil, it will be coerced to the zero value of the underlying type.

(ref reflect.Value)

// value. It dereferences recursively until it finds a non-pointer value. If the
// pointer is nil, it will be coerced to the zero value of the underlying type.
func derefPointer(ref reflect.Value) reflect.Value {
	if !ref.IsNil() {
		// Grab the value the pointer references.
		ref = ref.Elem()
	} else {
		// Coerce nil ptrs to zero'd values of their underlying type.
		ref = reflect.Zero(ref.Type().Elem())
	}

	// Recursively deref nested pointers.
	if ref.Kind() == reflect.Ptr {
		return derefPointer(ref)
	}

	return ref
