Method Detail
-
getEncodedLength
int getEncodedLength(int inputLength)
Return the expected output length of the encoding.- Parameters:
inputLength
- the input length of the data.- Returns:
- the output length of an encoding.
-
getMaxDecodedLength
int getMaxDecodedLength(int inputLength)
Return the maximum expected output length of a decoding. If padding is present the value returned will be greater than the decoded data length.- Parameters:
inputLength
- the input length of the encoded data.- Returns:
- the upper bound of the output length of a decoding.
