protectedvirtual |
Input the last block of data.
inString | the input byte buffer |
length | the size of the input buffer, in bytes |
LastPut() processes the last block of data and signals attached filters to do the same. LastPut() is always called. The pseudo algorithm for the logic is:
if totalLength < firstSize then length == totalLength else if totalLength <= firstSize+lastSize then length == totalLength-firstSize else lastSize <= length < lastSize+blockSize
