Method Details

readExternal

public void readExternal(ObjectInput in)
            throws IOException,
                   ClassNotFoundException

size

public long size()
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.
Overrides:
size in interface Header

writeExternal

public void writeExternal(ObjectOutput out)
            throws IOException
