Class SSCluster

java.lang.Object
  cgl.narada.topology.viewer.Node
      cgl.narada.topology.viewer.SSCluster

public class SSCluster
extends Node

This class represents all the super super clusters consisting of super clusters. The super super cluster is fourth level in the node address. If node's address is 1.2.3.4 then the super super cluster id is 1

Method Detail

insertSuperCluster

public void insertSuperCluster(int superClusterId,
                               int clusterId,
                               int nodeId)
                        throws TopologyException

Adds a new super cluster to the list. Depending upon the total number of super clusters in the list, decide the new positions for each of the super cluster.

Parameters:

superClusterId - id of a super cluster.

clusterId - id of a cluster.

nodeId - id of a node.

Throws:

TopologyException - if due to some problem. super cluster is found null during insertion of a node

deleteSuperCluster

public void deleteSuperCluster(int superClusterId,
                               int clusterId,
                               int nodeId,
                               List nodesToBeDeleted)
                        throws TopologyException

Deletes an existing super cluster inside the super super cluster. Repositions all other nodes reculrsively.

Parameters:

superClusterId - id of a super cluster.

clusterId - id of a cluster.

nodeId - id of a node.

nodesToBeDeleted - a List which will contain node addresses of the nodes being deleted.

Throws:

TopologyException - if no such super cluster id found while node deletion.

deleteAllSuperClusters

public void deleteAllSuperClusters(List nodesToBeDeleted)

Deletes all the super clusters present in this super super cluster.

Parameters:

nodesToBeDeleted - a List which will contain node addresses of the nodes being deleted.

getNodeAtParticularCoordinates

public Node getNodeAtParticularCoordinates(int x,
                                           int y)

Finds out super cluster nearest to the specified coordinates. Then passes control to the super cluster for finding a nearest cluster.

Parameters:

x - X-coordinate

y - Y-coordinate

Returns:

Node nearest to specified coordinates.

drawSuperSuperCluster

public void drawSuperSuperCluster(Graphics g,
                                  int limitX1,
                                  int limitY1,
                                  int limitX2,
                                  int limitY2)

Draws the super super cluster only if its part is visible on the screen. Draws all the super clusters inside it.

Parameters:

g - Graphics object for image drawing.

limitX1 - lower limit for X-coordinate

limitY1 - lower limit for Y-coordinate

limitX2 - upper limit for X-coordinate

limitY2 - upper limit for Y-coordinate

getParticularNode

public Node getParticularNode(int superClusterId,
                              int clusterId,
                              int nodeId)

Returns a node in this super super cluster with specified super cluster, cluster and node id.

Parameters:

superClusterId - id of a super cluster.

clusterId - id of a cluster.

nodeId - id of a node.

Returns:

Node

repositionSuperClusters

public void repositionSuperClusters()

Gets the new Position objects and assign then to all the super clusters inside this super super cluster. Recurdively calls repositionNodes() for each of the super cluster.
