encode

public int encode(char[] src,
 int soff,
 int len,
 Writer dst)
           throws IOException

Encode a string to the "x-www-form-urlencoded" form, enhanced with the UTF-8-in-URL proposal. This is what happens:

• The ASCII characters 'a' through 'z', 'A' through 'Z', and '0' through '9' remain the same.

• The unreserved characters - _ . ! ~ * ' ( ) remain the same.

• The space character ' ' is not converted into a plus sign '+'.

• All other ASCII characters are converted into the 3-character string "%xy", where xy is the two-digit hexadecimal representation of the character code

• All non-ASCII characters are encoded in two steps: first to a sequence of 2 or 3 bytes, using the UTF-8 algorithm; secondly each of these bytes is encoded as "%xx".

Specified by:

encode in class Encoder

Parameters:

src - Char array to encode.

soff - Offset in the src array at which to begin reading.

len - Length of src array to encode.

dst - Writer in which to write the encoded chars.

Returns:

Length of chars written to dst.

Throws:

IOException

decode

public int decode(char[] src,
 int soff,
 int len,
 Writer dst)
           throws IOException

Decodes from URL-escaped format.

Specified by:

decode in class Encoder

Parameters:

src - Char array to decode.

soff - Offset in the src array at which to begin reading.

len - Length of src array to decode.

dst - Writer in which to write the decoded chars.

Returns:

Length of chars written to dst.

Throws:

IOException
