Class StoreMessage

java.lang.Object
  org.planx.xmlstore.routing.operation.OriginMessage
      org.planx.xmlstore.routing.operation.DataMessage
          org.planx.xmlstore.routing.operation.StoreMessage

All Implemented Interfaces:

Message, Streamable

public class StoreMessage
extends DataMessage

Message representing a mapping from a key to a value. If upd is true a StoreMessage with the same key is expected as reply if the receiving node has a newer version of the mapping.

void	fromStream(DataInput in) Reads the internal state of the Streamable object from the input stream.
void	toStream(DataOutput out) 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.

StoreMessage

public StoreMessage(DataInput in)
             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 DataMessage

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 DataMessage

Throws:

IOException

updateRequested

public boolean updateRequested()

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

Overrides:

code in class DataMessage

toString

public String toString()

Overrides:

toString in class DataMessage
