|---|
| public int | decode(byte[] data, int off, int length, java.io.OutputStream out)decode the Hex encoded byte data writing it to the given output stream,
whitespace characters will be ignored.
byte b1, b2;
int outLen = 0;
int end = off + length;
while (end > off)
{
if (!ignore((char)data[end - 1]))
{
break;
}
end--;
}

{
i++;
}

{

}
b2 = decodingTable[data[i++]];
out.write((b1 << 4) | b2);
outLen++;
}
return outLen;

| public int | decode(java.lang.String data, java.io.OutputStream out)decode the Hex encoded String data writing it to the given output stream,
whitespace characters will be ignored.

| public int | encode(byte[] data, int off, int length, java.io.OutputStream out)encode the input data producing a Hex output stream.
