      • size

        public int size()
        Description copied from class: Header
        To be implemented by subclasses. Return the size of this object for the serialized version of it. I.e. how many bytes this object takes when flattened into a buffer. This may be different for each instance, or can be the same. This may also just be an estimation. E.g. FRAG uses it on Message to determine whether or not to fragment the message. Fragmentation itself will be accurate, because the entire message will actually be serialized into a byte buffer, so we can determine the exact size.
