public ResponseWrapper(Response response)

Method Detail

getCharacterEncoding

public String getCharacterEncoding()

Description copied from interface: Response

Returns the name of the charset used for the MIME body sent in this response.

If no charset has been assigned, it is implicitly set to ISO-8859-1 (Latin-1).

See RFC 2047 (http://ds.internic.net/rfc/rfc2045.txt) for more information about character encoding and MIME.

Specified by:

getCharacterEncoding in interface Response

Returns:

a String specifying the name of the charset, for example, ISO-8859-1

setLocale

public void setLocale(Locale loc)

Description copied from interface: Response

Sets the locale of the response, setting the headers (including the Content-Type's charset) as appropriate. By default, the response locale is the default locale for the server.

Specified by:

setLocale in interface Response

Parameters:

loc - the locale of the response

See Also:

Response.getLocale()

getLocale

public Locale getLocale()

Description copied from interface: Response

Returns the locale assigned to the response.

Specified by:

getLocale in interface Response

See Also:

Response.setLocale(Locale)

createCookie

public Cookie createCookie(String name,
                           String value)

Description copied from interface: Response

Constructs a cookie with a specified name and value.

The name must conform to RFC 2109. That means it can contain only ASCII alphanumeric characters and cannot contain commas, semicolons, or white space or begin with a $ character. The cookie's name cannot be changed after creation.

The value can be anything the server chooses to send. Its value is probably of interest only to the server. The cookie's value can be changed after creation with the setValue method.

By default, cookies are created according to the Netscape cookie specification. The version can be changed with the setVersion method.

Specified by:

createCookie in interface Response

Parameters:

name - a String specifying the name of the cookie

value - a String specifying the value of the cookie

addCookie

public void addCookie(Cookie cookie)

Description copied from interface: Response

Adds the specified cookie to the response. This method can be called multiple times to set more than one cookie.

Specified by:

addCookie in interface Response

Parameters:

cookie - the Cookie to return to the client

encodeURL

public String encodeURL(String url)

Description copied from interface: Response

Encodes the specified URL by including the session ID in it, or, if encoding is not needed, returns the URL unchanged. The implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary.

For robust session tracking, all URLs emitted by a servlet should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.

Specified by:

encodeURL in interface Response

Parameters:

url - the url to be encoded.

Returns:

the encoded URL if encoding is needed; the unchanged URL otherwise.

containsHeader

public boolean containsHeader(String name)

Description copied from interface: Response

Returns a boolean indicating whether the named response header has already been set.

Specified by:

containsHeader in interface Response

Parameters:

name - the header name

Returns:

true if the named response header has already been set; false otherwise

setDateHeader

public void setDateHeader(String name,
                          long date)

Description copied from interface: Response

Sets a response header with the given name and date-value. The date is specified in terms of milliseconds since the epoch. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.

Specified by:

setDateHeader in interface Response

Parameters:

name - the name of the header to set

date - the assigned date value

See Also:

Response.containsHeader(String), Response.addDateHeader(String, long)

addDateHeader

public void addDateHeader(String name,
                          long date)

Description copied from interface: Response

Adds a response header with the given name and date-value. The date is specified in terms of milliseconds since the epoch. This method allows response headers to have multiple values.

Specified by:

addDateHeader in interface Response

Parameters:

name - the name of the header to set

date - the additional date value

See Also:

Response.setDateHeader(String, long)

setHeader

public void setHeader(String name,
                      String value)

Description copied from interface: Response

Sets a response header with the given name and value. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.

Specified by:

Parameters:

name - the name of the header

value - the header value

setIntHeader

public void setIntHeader(String name,
                         int value)

Description copied from interface: Response

Sets a response header with the given name and int value. If the header had already been set, the new value overwrites the previous one. The containsHeader method can be used to test for the presence of a header before setting its value.

Parameters:

name - the name of the header to set

value - the assigned int value

See Also:

Response.containsHeader(String), Response.addIntHeader(String, int)
