        request - a Request. It cannot be null.
      • getAttribute

        public java.lang.Object getAttribute​(java.lang.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
      • getContextPath

        public java.lang.String 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
      • getDateHeader

        public long getDateHeader​(java.lang.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:

        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.

        Specified by:
        isXHR in interface Request
        Returns:
        true if the request has an XmlHttpRequest origin

        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

        Specified by:
        getServerPort in interface Request
        Returns:
        an integer specifying the port number

        public java.lang.String getRemoteHost()
        Description copied from interface: Request

        Returns:
        a String containing the fully qualified name of the client
