<DL>
<A NAME="absfact"></A>
<DT><B><A HREF="pat3afs.htm" TARGET="_mainDisplayFrame">Abstract Factory (87)</A></B>
<DD>Provide an interface for creating families of related or dependent
objects without specifying their concrete classes.
<DT><B><A HREF="pat3bfs.htm" TARGET="_mainDisplayFrame">Builder (97)</A></B>
<DD>Separate the construction of a complex object from its representation
so that the same construction process can create different
representations.
<A NAME="cat-factory"></A>
<DT><B><A HREF="pat3cfs.htm" TARGET="_mainDisplayFrame">Factory Method (107)</A></B>
<DD>Define an interface for creating an object, but let subclasses decide
which class to instantiate. Factory Method lets a class defer
instantiation to subclasses.
<A NAME="cat-proto"></A>
<DT><B><A HREF="pat3dfs.htm" TARGET="_mainDisplayFrame">Prototype (117)</A></B>
<DD>Specify the kinds of objects to create using a prototypical
instance, and create new objects by copying this prototype.
<A NAME="cat-single"></A>
<DT><B><A HREF="pat3efs.htm" TARGET="_mainDisplayFrame">Singleton (127)</A></B>
<DD>Ensure a class only has one instance, and provide a global point
of access to it.
<A NAME="disc3"></A>
<DT><B><A HREF="disc3fs.htm" TARGET="_mainDisplayFrame">Discussion
of Creational Patterns</A></B>
</DL>
<A NAME="structural"></A>
<H2><A HREF="#behavioral"><IMG SRC="gifsb/down3.gif" BORDER=0></A>
<A HREF="chap4fs.htm" TARGET="_mainDisplayFrame">Structural Patterns</A></H2>
<DL>
<A NAME="adapter"></A>
<DT><B><A HREF="pat4afs.htm" TARGET="_mainDisplayFrame">Adapter (139)</A></B>
<DD>Convert the interface of a class into another interface clients
expect. Adapter lets classes work together that couldn't otherwise
because of incompatible interfaces.
<DT><B><A HREF="pat4bfs.htm" TARGET="_mainDisplayFrame">Bridge (151)</A></B>
<DD>Decouple an abstraction from its implementation so that the two
can vary independently.
<DT><B><A HREF="pat4cfs.htm" TARGET="_mainDisplayFrame">Composite (163)</A></B>
<DD>Compose objects into tree structures to represent part-whole
hierarchies. Composite lets clients treat individual objects and
compositions of objects uniformly.
<A NAME="cat-dec"></A>
<DT><B><A HREF="pat4dfs.htm" TARGET="_mainDisplayFrame">Decorator (175)</A></B>
<DD>Attach additional responsibilities to an object dynamically.
Decorators provide a flexible alternative to subclassing for extending
functionality.
<A NAME="cat-facade"></A>
<DT><B><A HREF="pat4efs.htm" TARGET="_mainDisplayFrame">Facade (185)</A></B>
<DD>Provide a unified interface to a set of interfaces in a subsystem.
Facade defines a higher-level interface that makes the subsystem
easier to use.
<A NAME="cat-flywt"></A>
<DT><B><A HREF="pat4ffs.htm" TARGET="_mainDisplayFrame">Flyweight (195)</A></B>
<DD>Use sharing to support large numbers of fine-grained objects efficiently.
<A NAME="cat-proxy"></A>
<DT><B><A HREF="pat4gfs.htm" TARGET="_mainDisplayFrame">Proxy (207)</A></B>
<DD>Provide a surrogate or placeholder for another object to control
access to it.
<A NAME="disc4"></A>
<DT><B><A HREF="disc4fs.htm" TARGET="_mainDisplayFrame">Discussion
of Structural Patterns</A></B>
</DL>
<A NAME="behavioral"></A>
<H2><A HREF="#last"><IMG SRC="gifsb/down3.gif" BORDER=0></A>
<A HREF="chap5fs.htm" TARGET="_mainDisplayFrame">Behavioral Patterns</A></H2>
<DL>
<DT><B><A HREF="pat5afs.htm" TARGET="_mainDisplayFrame">Chain of Responsibility (223)</A></B>
<DD>Avoid coupling the sender of a request to its receiver by giving more
than one object a chance to handle the request. Chain the receiving
objects and pass the request along the chain until an object
handles it.
<DT><B><A HREF="pat5bfs.htm" TARGET="_mainDisplayFrame">Command (233)</A></B>
<DD>Encapsulate a request as an object, thereby letting you parameterize
clients with different requests, queue or log requests, and support
undoable operations.
<DT><B><A HREF="pat5cfs.htm" TARGET="_mainDisplayFrame">Interpreter (243)</A></B>
<DD>Given a language, define a represention for its grammar along with an
interpreter that uses the representation to interpret sentences in the
language.
<DT><B><A HREF="pat5dfs.htm" TARGET="_mainDisplayFrame">Iterator (257)</A></B>
<DD>Provide a way to access the elements of an aggregate object
sequentially without exposing its underlying representation.
<A NAME="cat-media"></A>
<DT><B><A HREF="pat5efs.htm" TARGET="_mainDisplayFrame">Mediator (273)</A></B>
<DD>Define an object that encapsulates how a set of objects interact.
Mediator promotes loose coupling by keeping objects from referring to
each other explicitly, and it lets you vary their interaction
independently.
<A NAME="cat-memen"></A>
<DT><B><A HREF="pat5efs.htm" TARGET="_mainDisplayFrame">Memento (283)</A></B>
<DD>Without violating encapsulation, capture and externalize an object's
internal state so that the object can be restored to this state later.
<DT><B><A HREF="pat5gfs.htm" TARGET="_mainDisplayFrame">Observer (293)</A></B>
<DD>Define a one-to-many dependency between objects so that when one
object changes state, all its dependents are notified and updated
automatically.
<A NAME="cat-state"></A>
<DT><B><A HREF="pat5hfs.htm" TARGET="_mainDisplayFrame">State (305)</A></B>
<DD>Allow an object to alter its behavior when its internal state changes.
The object will appear to change its class.
<A NAME="cat-strat"></A>
<DT><B><A HREF="pat5ifs.htm" TARGET="_mainDisplayFrame">Strategy (315)</A></B>
<DD>Define a family of algorithms, encapsulate each one, and make them
interchangeable. Strategy lets the algorithm vary independently from
clients that use it.
<A NAME="cat-tempmeth"></A>
<DT><B><A HREF="pat5ifs.htm" TARGET="_mainDisplayFrame">Template Method (325)</A></B>
<DD>Define the skeleton of an algorithm in an operation, deferring some
steps to subclasses. Template Method lets subclasses redefine
certain steps of an algorithm without changing the algorithm's
structure.
<A NAME="cat-visit"></A>
<DT><B><A HREF="pat5kfs.htm" TARGET="_mainDisplayFrame">Visitor (331)</A></B>
<DD>Represent an operation to be performed on the elements of an object
structure. Visitor lets you define a new operation without changing the
classes of the elements on which it operates.
