Method Detail

getAddress

public int getAddress()

Get address.

Overrides:

getAddress in class PastryAppl

Returns:

gets the address.

receiveMessage

public void receiveMessage(Message msg)

Receives a message from the outside world.

Overrides:

receiveMessage in class PastryAppl

Parameters:

msg - the message that was received.

setReady

protected void setReady()

Can be overloaded to do additional things before going ready. For example, verifying that other nodes are aware of us, so that consistent routing is guaranteed.

broadcastRows

public void broadcastRows(JoinRequest jr)

Broadcasts the route table rows.

Parameters:

jr - the join row.

messageForAppl

public void messageForAppl(Message msg)

Should not be called becasue we are overriding the receiveMessage() interface anyway.

Specified by:

messageForAppl in class PastryAppl

Parameters:

msg - the message that is arriving.

deliverWhenNotReady

public boolean deliverWhenNotReady()

We always want to receive messages.

Overrides:

deliverWhenNotReady in class PastryAppl

Returns:

false unless the node is a service
