Field Summary

protected Node	center Used as center: nodes will link to this node.
protected boolean	pack If true, method pack() is invoked on the initialized protocol
protected int	pid The protocol we want to wire

Constructor Summary

pack

If this config property is defined, method Linkable.pack() is invoked on the specified protocol at the end of the wiring phase. Default to false.

Field Detail

pid

protected final int pid

The protocol we want to wire

pack

protected final boolean pack

If true, method pack() is invoked on the initialized protocol

center

protected Node center

Used as center: nodes will link to this node.

public StarNI(java.lang.String prefix)

Method Detail

initialize

public void initialize(Node n)

Adds a link to a fixed node, the center. This fixed node remains the same throughout consecutive calls to this method. If the center fails in the meantime, a new one is chosen so care should be taken. The center is the first node that is not down (starting from node 0, 1, etc) at the time of the first call to the function. When a new center needs to be chosen (the current one is down), the new center is again the first one which is up. If no nodes are up, the node with the last index is set as center, and selection of a new center is always attempted when this method is called again.
