public class EncodingConverter
extends EncodingConverter

The class contains utility methods for converting a String into a MIME format called "x-www-form-urlencoded" and vice versa.

To convert a String, each character is examined in turn:

• The ASCII characters 'a' through 'z', 'A' through 'Z', and '0' through '9' remain the same.
• The space character ' ' is converted into a plus sign '+'.
• All other characters are converted into an 8-bit byte sequence using a character encoding and the resulting bytes are each represented as a 3-character string "%xy", where xy is the two-digit hexadecimal representation of the byte.

Deployment Notes:

The EncodingConverter is a replacement for WTURLEncoder and is instance based. The EncodingConverter should not be shared amongst threads or used as a static instance unless appropriate synchronization blocks are used to protect the internal buffers from overrighting. This can be done one of two ways. Firstly by declaring the method which calls the encode/decode methods as synchronized, or by placing a syncrhonized block around the actually calls to encode/decode as shown below.





static EncodingConverter staticEncoder = new EncodingConverter();

public void sampleMethod(String s)
{

synchronized( staticEncoder )
{

staticEncoder.encode(s);

}

}
