Server-Side Slice-to-Objective‑C Mapping : 20.2 Introduction
Copyright © 2003-2009 ZeroC, Inc.

20.2 Introduction

The mapping for Slice data types to Objective‑C is identical on the client side and server side, except for operation parameters, which map slightly differently for types that have mutable and immutable variants (strings, sequence, and dictionaries). This means that the mappings in Chapter 18 also apply to the server side. However, for the server side, there are a few additional things you need to know, specifically:
• how to initialize and finalize the server-side run time
• how to implement servants
• how to pass parameters and throw exceptions
• how to create servants and register them with the Ice run time.
We discuss these topics in the remainder of this chapter.
