      public RequestFacade(Request request)
      Construct a wrapper for the specified request.
      Parameters:
      request - The request to be wrapped

    • clear

      public void clear()
      Clear facade.

    • clone

      protected Object clone() throws CloneNotSupportedException
      Prevent cloning the facade.

    • getAttribute

      public Object getAttribute(String name)
      Description copied from interface: javax.servlet.ServletRequest
      Returns the value of the named attribute as an Object, or null if no attribute of the given name exists.

      Attributes can be set two ways. The servlet container may set attributes to make available custom information about a request. For example, for requests made using HTTPS, the attribute javax.servlet.request.X509Certificate can be used to retrieve information on the certificate of the client. Attributes can also be set programmatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.

      Attribute names should follow the same conventions as package names. Names beginning with java.* and javax.* are reserved for use by the Servlet specification. Names beginning with sun.*, com.sun.*, oracle.* and com.oracle.*) are reserved for use by Oracle Corporation.

      Specified by:
      getAttribute in interface ServletRequest

    • getCharacterEncoding

      public String getCharacterEncoding()
      Description copied from interface: javax.servlet.ServletRequest
      Returns the name of the character encoding used in the body of this request. This method returns null if the no character encoding has been specified. The following priority order is used to determine the specified encoding:

      3. container default via container specific configuration
      Specified by:

    • getContentType

      public String getContentType()
      Description copied from interface: javax.servlet.ServletRequest
      Returns the MIME type of the body of the request, or null if the type is not known. For HTTP servlets, same as the value of the CGI variable CONTENT_TYPE.

      Returns the value of a request parameter as a String, or null if the parameter does not exist. Request parameters are extra information sent with the request. For HTTP servlets, parameters are contained in the query string or posted form data.

      You should only use this method when you are sure the parameter has only one value. If the parameter might have more than one value, use ServletRequest.getParameterValues(java.lang.String).

      If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned by getParameterValues.

      If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via ServletRequest.getInputStream() or ServletRequest.getReader() can interfere with the execution of this method.

      Attribute names should follow the same conventions as package names. Names beginning with java.* and javax.* are reserved for use by the Servlet specification. Names beginning with sun.*, com.sun.*, oracle.* and com.oracle.*) are reserved for use by Oracle Corporation.
      If the object passed in is null, the effect is the same as calling ServletRequest.removeAttribute(java.lang.String).
      It is warned that when the request is dispatched from the servlet resides in a different web application by RequestDispatcher, the object set by this method may not be correctly retrieved in the caller servlet.

      Specified by:
      setAttribute in interface ServletRequest
      Parameters:

      Specified by:
      removeAttribute in interface ServletRequest
      Parameters:
      name - a String specifying the name of the attribute to remove

      public Locale getLocale()
      Description copied from interface: javax.servlet.ServletRequest
      Returns the preferred Locale that the client will accept content in, based on the Accept-Language header. If the client request doesn't provide an Accept-Language header, this method returns the default locale for the server.
      Specified by:
      getLocale in interface ServletRequest
      Returns:
      the preferred Locale for the client

    • getLocales

      public Enumeration<Locale> getLocales()
      Description copied from interface: javax.servlet.ServletRequest
      Returns an Enumeration of Locale objects indicating, in decreasing order starting with the preferred locale, the locales that are acceptable to the client based on the Accept-Language header.

    • getRequestDispatcher

      public RequestDispatcher getRequestDispatcher(String path)
      Description copied from interface: javax.servlet.ServletRequest
      Returns a RequestDispatcher object that acts as a wrapper for the resource located at the given path. A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.

      The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns null if the servlet container cannot return a RequestDispatcher.

      The difference between this method and ServletContext.getRequestDispatcher(java.lang.String) is that this method can take a relative path.

      Specified by:
      getRequestDispatcher in interface ServletRequest
      Parameters:
      path - a String specifying the pathname to the resource. If it is relative, it must be relative against the current servlet.

      To reconstruct a URL with a scheme and host, use HttpServletRequest.getRequestURL().

      a String containing the part of the URL from the protocol name up to the query string

    • getRequestURL

      public StringBuffer getRequestURL()
      Description copied from interface: javax.servlet.http.HttpServletRequest
      Reconstructs the URL the client used to make the request. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters.

      Because this method returns a StringBuffer, not a string, you can modify the URL easily, for example, to append query parameters.

      This method is useful for creating redirect messages and for reporting errors.

      Specified by:
      getRequestURL in interface HttpServletRequest
      Returns:
      a StringBuffer object containing the reconstructed URL

    • getServletPath

      This method will return an empty string ("") if the servlet used to process this request was matched using the "/*" pattern.

      Specified by:
      getServletPath in interface HttpServletRequest
      Returns:
      a String containing the name or path of the servlet being called, as specified in the request URL, decoded, or an empty string if the servlet used to process the request is matched using the "/*" pattern.

      Specified by:
      getSession in interface HttpServletRequest
      Parameters:
      create - true to create a new session for this request if necessary; false to return null if there's no current session
