load

public void load(javax.servlet.http.HttpServletRequest request)

Parses and loads the given request.

Before all, extractBaseURI(HttpServletRequest) is called so that extracting the base URI from the request. If this URI is different from the URI stored in this UWSUrl, load(URL) is called so that parsing only the request URL and then this method ends immediately.

Otherwise this method sets its fields as following:

• requestURL = HttpServletRequest.getRequestURL()
• urlHeader = ServletRequest.getScheme()+"://"+ServletRequest.getServerName()+":"+ServletRequest.getServerPort()+HttpServletRequest.getContextPath()
• requestURI = HttpServletRequest.getRequestURI()
• uwsURI = HttpServletRequest.getPathInfo()
• for jobListName, jobId and attributes, see loadUwsURI()

Note: If the given request is NULL, all fields are set to NULL.

Parameters:

request - The request to parse and to load.

See Also:

extractBaseURI(HttpServletRequest), load(URL), loadUwsURI()
