Method Detail

getInstance

public static ParameterSupport getInstance(javax.servlet.http.HttpServletRequest request)

Returns the ParameterSupport instance supporting request parameter for the give request. For a single request only a single instance is actually used. This single instance is cached as a request attribute. If such an attribute already exists which is not an instance of this class, the request parameter is replaced.

Parameters:

request - The HttpServletRequest for which to return request parameter support.

Returns:

The ParameterSupport for the given request.

getParameterSupportRequestWrapper

public static javax.servlet.http.HttpServletRequestWrapper getParameterSupportRequestWrapper(javax.servlet.http.HttpServletRequest request)

Returns a HttpServletRequestWrapper which implements request parameter access backed by an instance of the ParameterSupport class.

If used in a Servlet API 3 context, this method supports the additional Part API introduced with Servlet API 3.

Parameters:

request - The HttpServletRequest to wrap

Returns:

The wrapped request
