            throws IOException

Throws:

IOException

Method Detail

fromStream

public void fromStream(DataInput in)
                throws IOException

Description copied from interface: Streamable

Reads the internal state of the Streamable object from the input stream. Immutable objects should throw an UnsupportedOperationException, and instead implement a constructor as described above.

Specified by:

fromStream in interface Streamable

Overrides:

fromStream in class OriginMessage

Throws:

IOException

toStream

public void toStream(DataOutput out)
              throws IOException

Description copied from interface: Streamable

Writes the internal state of the Streamable object to the output stream in a format that can later be read by the same Streamble class using the Streamable.fromStream(java.io.DataInput) method.

Specified by:

toStream in interface Streamable

Overrides:

toStream in class OriginMessage

Throws:

IOException

getKey

public Identifier getKey()

getValue

public TimestampedValue getValue()

code

public byte code()

Description copied from interface: Message

The unique code for the message type, used to differentiate all messages from each other. Since this is of byte type there can be at most 256 different message types.

Specified by:

code in interface Message

Specified by:

code in class OriginMessage

toString

public String toString()

Overrides:

toString in class Object
