Compact and full representation of a generic servlet
to highlight this aspect. Optionally, the servlet can be tagged with {Single
ThreadServlet=True} instead to clearly identify this on the diagram in a somewhat more compact format.
An example of a servlet that implements the SingleThreadModel is shown in
Figure 10-6.
The HttpServlet class is modeled similarly to GenericServlet, but with the
<<Http_Servlet>> stereotype applied. It can also include the life cycle methods,the
convenience method,and any of the HTTP request handlers previously discussed.
