Called when the public setup method is called. At this time, the sim parameter has been initialized, and getAllNodes also should be valid to call.

Overrides:

setUp in class TreeManager

getRootNodes

public java.util.Collection<Node> getRootNodes()

Description copied from class: TreeManager

After a tree reconstruction, returns the nodes that are the roots of their stripe trees. It is assumed that the Node is the root of its primary stripe and of no other. That is, Node getParent( getStripeId() ) should return null.

Specified by:

getRootNodes in class TreeManager

Returns:

non-null Collection of 0 or more Node.

rebuildTree

public void rebuildTree()

Description copied from class: TreeManager

A method to completely rebuild the Node tree given all nodes in the system.

Specified by:

rebuildTree in class TreeManager

getNextNodeId

public int getNextNodeId()

Description copied from class: TreeManager

Returns the next node ID using the node ID allocation algorithm from this TreeManager.

Specified by:
