Maintains a map of HTTP request handlers keyed by a request URI pattern.
Patterns may have three formats:
  • *
  • *&lt;uri&gt;
  • &lt;uri&gt;*

This class can be used to resolve an instance of HttpAsyncRequestHandler matching a particular request URI. Usually the resolved request handler will be used to process the request with the specified request URI.
Since:4.2
Deprecated:(4.3) use UriHttpAsyncRequestHandlerMapper
