Is there any sort of static method for obtaining the encode and decode
size for data passed through HexEncoder, HexDecoder, Base64Encoder,
Base64Decoder, Base32Encoder, and Base32Decoder?
If not, is there any reason anyone would be against adding such methods?
Much like the encryption classes have an CiphertextLength and
MaxPlaintextLength, it would be much more convienient if these encoder
and decoder classes has methods along the lines of EncodeLength and
DecodeLength so that code, such as the following, did not have to be
written to figure the actual lengths:
ArraySink *sizeSink = new ArraySink(0, 0);
Base64Encoder sizeEnc64(sizeSink);
sizeEnc64.PutMessageEnd(NULL, sizeof(T));
return sizeSink->TotalPutLength();
Are there any objections to having methods such as these?
virtual unsigned int EncodeLength(unsigned int dataLength) const = 0;
virtual unsigned int DecodeLength(unsigned int dataLength) const = 0;
