Question

I need help to write a code for these conditions

public void receiveMsgFromNode(String msg, Integer id, Integer r, NodeTransitionFunction f) {

// PRE: msg is a message,

// id is the ID of the sending node,

// r is the current value of r from the forward transition function,

// f is the forward transition function

// POST: If this is the destination node, stop;

// otherwise, send the message onwards.

// Add ID of current (receiving) node to local MessageTrackCheck

Solution

public void receiveMsgFromNode(String msg, Integer id, Integer r, NodeTransitionFunction f) {
// PRE: msg is a message,
// id is the ID of the sending node,
// r is the current value of r from the forward transition function,
// f is the forward transition function
// POST: If this is the destination node, stop;
// otherwise, send the message onwards.
// Add ID of current (receiving) node to local MessageTrackCheck
if (!n.equals(r)) { // if this node is not the same node as sender node
Integer nextId = f.apply(r);
sendMsgToNode((Node)m.get(nextId), msg, nextId, f);
t.add(id);
}
}

Thank You
