Method Detail

filterImpactedNodes

public Graph filterImpactedNodes(Graph graph,
                                 String changedNodeName)

Forward graph of impact analysis. Collect impacted nodes from a changed node. Set changedNode status to Status.CHANGED and impacted nodes status to Status.IMPACTED

Parameters:

graph -

name - of changedNode (= rule name)

Returns:

sub graph which contains only changed node and impacted nodes

filterImpactedNodes

public Graph filterImpactedNodes(Graph graph,
                                 Node changedNode)

Forward graph of impact analysis. Collect impacted nodes from a changed node. Set changedNode status to Status.CHANGED and impacted nodes status to Status.IMPACTED

Parameters:

graph -

changedNode -

Returns:

sub graph which contains only changed node and impacted nodes

filterImpactingNodes

public Graph filterImpactingNodes(Graph graph,
                                  String targetNodeName)

Backward graph of impact analysis. Collect impacting nodes from a target node. Set targetNode status to Status.IMPACTED and impacting nodes status to Status.IMPACTING

Parameters:

graph -

name - of targetNode (= rule name)

Returns:

sub graph which contains only target node and impacting nodes

filterImpactingNodes

public Graph filterImpactingNodes(Graph graph,
                                  Node targetNode)

Backward graph of impact analysis. Collect impacting nodes from a target node. Set targetNode status to Status.TARGET and impacting nodes status to Status.IMPACTING

Parameters:

graph -

targetNode -

Returns:

sub graph which contains only target node and impacting nodes
