Class RequestImpl

  • All Implemented Interfaces:
    Request
    public class RequestImpl
extends java.lang.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).

        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:
        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 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

      • setAttribute

        public void setAttribute​(java.lang.String name,
                         java.lang.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

        public java.lang.String getMethod()
        Description copied from interface: Request
        Returns the name of the HTTP method with which this request was made, for example, GET, POST, or PUT.
        Specified by:
        getMethod in interface Request
        Returns:
        a string specifying the name of the method with which this request was made

      • getServerName

        public java.lang.String 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

        getLocalPort in interface Request
        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.
        Specified by:
        getServerPort in interface Request
        Returns:
        an integer specifying the port number
        Since:
        5.2.5

      • getRemoteHost

        public java.lang.String 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
