Chapter 21. Namespace Reference

The quick reference is organized into
chaptersone per namespace. Each chapter begins with an
overview of the namespace and includes a hierarchy diagram for the
types (classes, interfaces, enumerations, delegates, and structs) in
the namespace. Quick-reference entries for all the types in the
namespace follow the overview.

Figure 21-1 is a sample diagram showing the notation
used in this book. This notation is similar to that used in
O'Reilly's

Java in a
Nutshell , but it borrows some features from UML.

Figure 21-1. Class hierarchy notation

Classes marked as abstract are shown as a slanted
rectangle; classes marked as sealed are shown as
an octagonal rectangle. Inheritance is shown as a solid line from the
subtype, ending with a hollow triangle that points to the base class.
Two notations indicate interface implementation. The lollipop
notation is used most of the time, since it is easier to read. In
some cases, especially when many types implement a given interface,
the shaded box notation with the dashed line is used.

Important relationships between types (associations) are shown with a
dashed line ending with an arrow. The figures don't
show every possible association. Some types have strong containing
relationships with one another. For example, a
System.Net.WebException object instance includes a
System.Net.WebResponse object instance that represents the HTTP
response containing the error details (HTTP status code and error
message). To show this relationship, a filled diamond is attached to
the containing type with a solid line that points to the contained
type.

Entries are organized alphabetically by type and namespace so that
related types are grouped near one another. Thus, in order to look up
a quick-reference entry for a particular type, you must also know the
name of the namespace that contains that type. Usually, the namespace
is obvious from the context, and you should have no trouble looking
up the quick-reference entry you want. Use the tabs on the outside
edge of the book and the dictionary-style headers on the upper corner
of each page to help you find the namespace and type you are looking
for.

Occasionally, you may need to look up a type for which you do not
already know the namespace. In this case, refer to Appendix A: Type, Method, Property, and Field Index, which allows you to look up a type by
its name and identify what namespace it is part of, at the end of
this book.
