Class UrlEncoded

java.lang.Object
  extended by java.util.AbstractMap<K,V>
      extended by java.util.HashMap
          extended by org.mortbay.util.MultiMap
              extended by org.mortbay.util.UrlEncoded
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, java.util.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.

                  java.lang.String charset)
Method Detail

decode

public void decode(java.lang.String query)

decode

public void decode(java.lang.String query,
                   java.lang.String charset)

encode

public java.lang.String encode()
Encode Hashtable with % encoding.


encode

public java.lang.String encode(java.lang.String charset)
Encode Hashtable with % encoding.


encode

public java.lang.String encode(java.lang.String charset,
                               boolean equalsForNullValue)
Encode Hashtable with % encoding.

Parameters:
equalsForNullValue - if True, then an '=' is always used, even for parameters without a value. e.g. "blah?a=&b=&c=".

decodeTo

public static void decodeTo(java.lang.String content,
                            MultiMap map)

decodeTo

public static void decodeTo(java.lang.String content,
                            MultiMap map,
                            java.lang.String charset)
Decoded parameters to Map.

Parameters:
content - the string containing the encoded parameters

decodeTo

public static void decodeTo(byte[] data,
                            int offset,
                            int length,
                            MultiMap map,
                            java.lang.String charset)
Decoded parameters to Map.

Parameters:
data - the byte[] containing the encoded parameters

decodeString

public static java.lang.String decodeString(java.lang.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.


decodeString

public static java.lang.String decodeString(java.lang.String encoded,
                                            java.lang.String charset)
Decode String with % encoding. This method makes the assumption that the majority of calls will need no decoding.


decodeString

public static java.lang.String decodeString(java.lang.String encoded,
                                            int offset,
                                            int length,
                                            java.lang.String charset)
Decode String with % encoding. This method makes the assumption that the majority of calls will need no decoding.

public static java.lang.String encodeString(java.lang.String string,
                                            java.lang.String charset)
Perform URL encoding.

Parameters:
string -
Returns:
encoded string.
