public class RequestImpl extends Object implements Request
Basic implementation of Request that wraps around an HttpServletRequest. This is not threadsafe, nor should it need to be (each Request is handled by its own Thread).

    • getParameterNames

      Description copied from interface: Request
      Returns a list of query parameter names, in alphabetical order.

      getParameterNames in interface Request
    • getHeaderNames

      Description copied from interface: Request
      Returns the names of all headers in the request.
      Specified by:
      getHeaderNames in interface Request
    • getParameter

      public String getParameter(String name)
      Description copied from interface: Request
      Returns the query parameter value for the given name. Returns null if no such parameter is in the request. For a multi-valued parameter, returns just the first value.
      Specified by:
      getParameter in interface Request
    • getParameters

      public String[] getParameters(String name)
      Description copied from interface: Request
      Returns the parameter values for the given name. Returns null if no such parameter is in the request.
      Specified by:
      getParameters in interface Request
    • getHeader

      public String getHeader(String name)
      Description copied from interface: Request
      Returns the named header as a string, or null if not found.
      Specified by:
      getHeader in interface Request
    • getPath

      public String getPath()
      Description copied from interface: Request
      Returns the path portion of the request, which starts with a "/" and contains everything up to the start of the query parameters. It doesn't include the context path.
      Specified by:
      getPath in interface Request
    • getContextPath

      Description copied from interface: Request
      Returns the context path. This always starts with a "/" character and does not end with one, with the exception of servlets in the root context, which return the empty string.
      Specified by:
      getContextPath in interface Request
    • isSessionInvalidated

      public boolean isSessionInvalidated()
      Description copied from interface: Request
      Returns true if the request specified a session, and that session has been invalidated.
      Specified by:
      isSessionInvalidated in interface Request
      Returns:
      true if session was invalidated during this request
    • getSession

      public Session getSession(boolean create)
      Description copied from interface: Request
      Gets the Session. If create is false and the session has not be created previously, returns null. Also, if the session is invalidated and create is false, returns null. Invoking this method with true, when the session exists but has been invalidated, will force the creation of a new session.
      Specified by:
      getSession in interface Request
      Parameters:
      create - true to force the creation of the session
      Returns:
      the session (or null if create is false the session has not been previously created)
    • getLocale

      public Locale getLocale()
      Description copied from interface: Request
      Returns the locale of the client as determined from the request headers.
      Specified by:
      getLocale in interface Request
    • getDateHeader

      public long getDateHeader(String name)
      Description copied from interface: Request
      Returns the value of the specified request header as a long value that represents a Date object. Use this method with headers that contain dates, such as If-Modified-Since . The date is returned as the number of milliseconds since January 1, 1970 GMT. The header name is case insensitive. If the request did not have a header of the specified name, this method returns -1. If the header can't be converted to a date, the method throws an IllegalArgumentException.
      Specified by:
      getDateHeader in interface Request
      Parameters:
      name - a String specifying the name of the header
      Returns:
      a long value representing the date specified in the header expressed as the number of milliseconds since January 1, 1970 GMT, or -1 if the named header was not included with the reqest
    • isXHR

      public boolean isXHR()
      Description copied from interface: Request
      Returns true if the request originated on the client using XmlHttpRequest (the core of any Ajax behavior). Ajax action requests may behave quite differently than ordinary, page-based requests. This implementation currently depends on the client side setting a header: X-Requested-With=XMLHttpRequest (this is what Prototype does).
      Specified by:
      isXHR in interface Request
      Returns:
      true if the request has an XmlHttpRequest origin
    • isSecure

      public boolean isSecure()
      Description copied from interface: Request
      Returns a boolean indicating whether this request was made using a secure channel, such as HTTPS.
      Specified by:
      isSecure in interface Request
      Returns:
      a boolean indicating if the request was made using a secure channel
    • isRequestedSessionIdValid

      public boolean isRequestedSessionIdValid()
      Description copied from interface: Request
      Checks whether the requested session ID is still valid.
      Specified by:
      isRequestedSessionIdValid in interface Request
      Returns:
      true if the request included a session id that is still active, false if the included session id has expired
    • getAttribute

      public Object getAttribute(String name)
      Description copied from interface: Request
      Returns the value of the named attribute as an Object, or null if no attribute of the given name exists. Because this method is a wrapper around ServletRequest.getAttribute(String), it is case sensitive (unlike most of Tapestry).
      Specified by:
      getAttribute in interface Request
      Parameters:
      name - a String specifying the name of the attribute
      Returns:
      an Object containing the value of the attribute, or null if the attribute does not exist
    • getAttributeNames

      Description copied from interface: Request
      Returns a sorted list of attribute names.
      Specified by:
      getAttributeNames in interface Request
    • setAttribute

      public void setAttribute(String name, Object value)
      Description copied from interface: Request
      Stores an attribute in this request. Attributes are reset between requests (and remember that in Tapestry, there is usually two requests per operation: the action request that redirects to a render request).
      Specified by:
      setAttribute in interface Request
      Parameters:
      name - a String specifying the name of the attribute
      value - the Object to be stored, or null to remove the attribute
    • getMethod

      public String getMethod()
      Description copied from interface: Request

      Specified by:
      getMethod in interface Request
      Returns:
      a string specifying the name of the method with which this request was made
    • getServerName

      Description copied from interface: Request
      Returns the host name of the server to which the request was sent. It is the value of the part before ":" in the Host header, if any, or the resolved server name, or the server IP address.
      Specified by:
      getServerName in interface Request
      Returns:
      the name of the server
    • getLocalPort

      public int getLocalPort()
      Description copied from interface: Request
      Returns the Internet Protocol (IP) port number of the interface on which the request was received.
      Specified by:

      Returns:
      an integer specifying the port number
    • getServerPort

      public int getServerPort()
      Description copied from interface: Request
      Returns the port number to which the request was sent. It is the value of the part after ":" in the Host header, if any, or the server port where the client connection was accepted on.

      5.2.5
    • getRemoteHost

      Description copied from interface: Request
      Returns the fully qualified name of the client or the last proxy that sent the request. If the engine cannot or chooses not to resolve the hostname (to improve performance), this method returns the dotted-string form of the IP address.
      Specified by:
      getRemoteHost in interface Request
      Returns:
      a String containing the fully qualified name of the client
