org.mortbay.util
Class UrlEncoded

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap
          org.mortbay.util.MultiMap
              org.mortbay.util.UrlEncoded

All Implemented Interfaces:

Serializable, Cloneable, Map

public class UrlEncoded
extends MultiMap

Handles coding of MIME "x-www-form-urlencoded". This class handles the encoding and decoding for either the query string of a URL or the _content of a POST HTTP request.

Notes

The hashtable either contains String single values, vectors of String or arrays of Strings. This class is only partially synchronised. In particular, simple get operations are not protected from concurrent updates.

decodeString

public static String decodeString(String encoded)

Decode String with % encoding. This method makes the assumption that the majority of calls will need no decoding and uses the 8859 encoding.

                                  String charset)

Decode String with % encoding. This method makes the assumption that the majority of calls will need no decoding.

encodeString

Perform URL encoding. Assumes 8859 charset

Parameters:

string -

Returns:
