Method Detail

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

addDigest

public void addDigest(Digest digest)

toString

public java.lang.String toString()
Overrides:
toString in class Header

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException
Specified by:
writeExternal in interface java.io.Externalizable
Throws:
java.io.IOException

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException
Specified by:
readExternal in interface java.io.Externalizable
Throws:
java.io.IOException
java.lang.ClassNotFoundException

writeTo

public void writeTo(java.io.DataOutputStream out)
             throws java.io.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:
java.io.IOException

readFrom

public void readFrom(java.io.DataInputStream in)
              throws java.io.IOException,

                     java.lang.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:
java.io.IOException
java.lang.IllegalAccessException
java.lang.InstantiationException
