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.

Overrides:

size in class Header

writeTo

public void writeTo(DataOutputStream out)
             throws IOException

Description copied from interface: Streamable

Write the entire state of the current object (including superclasses) to outstream. Note that the output stream must not be closed

Specified by:

writeTo in interface Streamable

Throws:

IOException

readFrom

public void readFrom(DataInputStream in)
              throws IOException,
IllegalAccessException,
InstantiationException

Description copied from interface: Streamable

Read the state of the current object (including superclasses) from instream Note that the input stream must not be closed

Specified by:

readFrom in interface Streamable

Throws:

IOException

IllegalAccessException
