* Allows runtime discovery of the manner in

* implementation must be thread safe. Instances are returned from
* {@link HttpServletRequest#getServletMapping}.
*
* Following are some illustrative examples for various combinations
* of mappings. Consider the following Servlet declaration:
*
*
* <servlet>
* <servlet-name>MyServlet</servlet-name>
* <servlet-class>MyServlet</servlet-class>
* </servlet>
* <servlet-mapping>
* <servlet-name>MyServlet</servlet-name>

* <url-pattern>""</url-pattern>
* <url-pattern>*.extension</url-pattern>
* <url-pattern>/path/*</url-pattern>
* </servlet-mapping>
*
*
* The expected values of the properties for various incoming URI
* path values are as shown in this table. The {@code servletName}
* column is omitted as its value is always {@code MyServlet}.
*
*
* Expected values of properties for various URI paths
*
* URI Path (in quotes)
* matchValue
