Class HttpStreamSelector

java.lang.Object
  org.sapia.ubik.net.mplex.HttpStreamSelector

All Implemented Interfaces:

StreamSelector

public class HttpStreamSelector
extends java.lang.Object
implements StreamSelector

Implements a selection logic for HTTP requests. By default this selector will choose all HTTP request, as it looks for the token "HTTP/" as specified by the HTTP specification. This selector also gives the functionaly to select only a given HTTP method (like POST or GET) and/or to specify a pattern for the HTTP request path. If specify this request pattern must be the first characters of the request path to select (without any starts or regex expression). The current logic to determine if the request pattern matches is done using the startsWith() method of the java.lang.String object.
