- 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.
