public class MyServletRequest

extends MyRequest

implements javax.servlet.ServletRequest

Maintenant que l'on dispose des outils permettant de remplir la hashtable avec les tokens contenus dans le Header de la requete http, on peut implémenter l'interface ServletRequest fournit par Sun.

Il faut appeller à bonne escient la méthode hashtable.get(ATTRIBUT_QUI_NOUS_INTERESSE) ou alors si l'on veut toutes les attributs contenus dans la requete http, il suffit de faire hashtable.getKeys() etc ....

De maniere générale on utilise les méthodes de la class Hashtable pour avoir accés aux données qui nous intéressent.

Etant donné que l'on récupere les spécifiactions de Sun et que l'on respecte dans ce cas les commentaires des méthoes sont récupérées sur leurs spécifications

Method Detail

getAttribute

public java.lang.Object getAttribute(java.lang.String name)

PAS IMPLEMANTE

Returns the value of the named attribute as an Object. This method allows the servlet engine to give the servlet custom information about a request. This method returns null if no attribute of the given name exists.

Attribute names should follow the same conventions as package names. This specification reserves names matching java.*, javax.*, and sun.*.

Specified by:

getAttribute in interface javax.servlet.ServletRequest

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

public java.util.Enumeration getAttributeNames()

getAttributeNames in interface javax.servlet.ServletRequest

Returns:

an Enumeration of strings containing the names of the request's attributes

getCharacterEncoding

Returns:

a String containing the name of the chararacter encoding style, or null if the request does not use character encoding

getContentLength

public int getContentLength()

Returns the length, in bytes, of the content contained in the request and sent by way of the input stream or -1 if the length is not known. Same as the value of the CGI variable CONTENT_LENGTH.

an integer containing the length of the content in the request or -1 if the length is not known

getContentType

public java.lang.String getContentType()

Returns the MIME type of the content of the request, or null if the type is not known. Same as the value of the CGI variable CONTENT_TYPE.

Specified by:

getContentType in interface javax.servlet.ServletRequest

                                                throws java.io.IOException

Retrieves binary data from the body of the request as a ServletInputStream, which gives you the ability to read one line at a time.

Specified by:

getInputStream in interface javax.servlet.ServletRequest

Returns:

a ServletInputStream object containing the body of the request

Throws:

IllegalStateException - if the getReader() method has already been called for this request

java.io.IOException - if an input or output exception occurred

getParameter

public java.lang.String getParameter(java.lang.String name)

PAS IMPLEMENTE 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.

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 getParameterValues(java.lang.String).

If you use this method with a multivalued parameter, the servlet engine determines the return value.

Specified by:

getParameterNames in interface javax.servlet.ServletRequest

Returns:

an Enumeration of String objects, each String containing the name of a request parameter; or an empty Enumeration if the request has no parameters

getParameterValues

public java.lang.String[] getParameterValues(java.lang.String name)

Returns an array of String objects containing all of the values the given request parameter has, or null if the parameter does not exist. For example, in an HTTP servlet, this method returns an array of String objects containing the values of a query string or posted form.
