Smalltalk and Object Orientation: an Introduction - Free

Chapter 7: Smalltalk Constructs
This chapter presents further details of the Smalltalk language including the representation and use of
numbers, strings and characters.
Chapter 8: An Example Smalltalk Class
In Chapter 7, the reader is presented with a detailed worked example of software development in
Smalltalk. This example presents a very simple class definition which uses only those concepts which
have been introduced at this stage. The intention is t o illustrate how the constructs and language
elements can be combined in a real (if simple) program.
Chapter 9: Control and Iteration
This chapter introduces how control and iteration are achieved in Smalltalk. To do this a number of
concepts which are un ique to Smalltalk are also discussed (such as the block object). To simplify this
process for the reader, equivalent C constructs are illustrated beside Smalltalk constructs (where they
exist).
Chapter 10: The Collection Classes
This chapter discusses pro bably the most widely used class hierarchy in Smalltalk; the collection class
hierarchy. It presents the hierarchy in general and some of the commonly used collection classes. It also
illustrates how these classes can be used to construct other collection style classes such as queues and
stacks.
Chapter 11: Further Collection Classes
This chapter concludes the examination of the collection classes available in Smalltalk and presents an
application constructed using these classes.
Chapter 12: An Object Oriented Organizer
This chapter presents a detailed example application constructed using the collection classes. The
Organizer is intended as an electronic personal Organizer. It therefore possesses an address book, a
diary (or appointments section) and a section for notes. The remainder of this chapter describes one way
of implementing such an Organizer.
Chapter 13: Streams and Files
This chapter discusses the second most used class hierarchy in Smalltalk; the Stream classes. The
Stream classes are used (amongst other things) for accessing files. The Binary Object Streaming Service
for storing objects in files is also discussed.
Chapter 14: The Magnitude Class Hierarchy
This chapter considers the magnitude class and those classes which inherit from it. This includes the
Number hierarchy. The classes Character, Time and Date are also considered.
Chapter 15: Some More Tools of the Trade
This chapter introduces the use of breakpoints in Smalltalk, the purpose of the change list file and how
to file in and file out Smalltalk code.
Part 3: Object Oriented Design
Chapter 16: Object Oriented Analysis and Design
This chapter introduces the concepts of object oriented analysis and design. It reviews a number of the
more popular techniques such as OOA, OMT, Objector y and Booch. It also briefly considers the
unification of the OMT and Booch notations.
Chapter 17: The Unified Modeling Language
The Unified Modeling Language (or UML for short) is a third generation object -oriented modeling
language which adapts and exte nds the published notations used in the Booch, OMT and Objectory
methods. It is intended that the UML will form a single, common, widely usable modeling language for
