title: How are the fields delimited in a Serialized byte stram?
body: <p>I was wondering how were delimited the fields of a serialized object in a byte stream?</p>
  
  <p>Is there some kind of binary flag separating them, or are the length of each field defined at the beginning (or is it using another delimitation technique I didn't think of)?</p>
  
  <p>Thanks!</p>
