    Description copied from class: ERSCachingData
    
    Compute the hash for this data object. Implemented by subclasses; the result is cached by ERSCachingData.getHash(DigestCalculator, byte[]).
    
    Specified by:
    
    calculateHash in class ERSCachingData
    
    Parameters:
    
    digestCalculator - the digest calculator to use.
    
    previousChainHash - hash from an earlier chain to fold in, or null.
    
    Returns:
    
    the calculated hash.
