public class TwoByteEncoder

extends Encoder

Example Encoder implementation, that encodes 2 bytes as 1 char.

Encodes a Resource by reading it in as chars, at 2 bytes per char. The evenness of the resource's file length in bytes is encoded in the first char: even length is encoded as '2', uneven length as '1'. If that length is uneven, the file's first byte is encoded alone in the loworder part of the second char.

If you encode resorces using this class, you have to include the TwoByteDecoder class in the distribution of your software.

We supply this class as a free service to all users of the Cramfull Compiled Resources library. You are allowed to modify this source code, provided you move the class out of the be.arci package hierarchy.

            throws java.io.IOException

Description copied from class: Encoder

Encodes the resource file into a sequence of char-s; implementations must invoke write(char c) for each encoded char. The Decoder will read this char sequence in the same order.

Overrides:

encode in class Encoder

Tags copied from class: Encoder

Parameters:

di - a DataInput opened on the resource to encode.

iResourceLength - the number of bytes in the di that must be read and encoded.

getDecoderClassName

public java.lang.String getDecoderClassName()

The Decoder associated with this Encoder is be.arci.pub.TwoByteDecoder

Overrides:

getDecoderClassName in class Encoder

Returns:
