Modifier and Type	Method and Description
static Collection<CommunicationSummaryStatistics>	buildCommunicationSummaryTree(Collection<CommunicationSummaryStatistics> nodes) This method returns the supplied list of flat nodes as a set of tree structures with related nodes.
protected static Collection<CommunicationSummaryStatistics>	getRootCommunicationSummaryNodes(Map<String,CommunicationSummaryStatistics> nodeMap) This method returns the subset of supplied nodes that are root nodes.
protected static void	initCommunicationSummaryTreeNode(CommunicationSummaryStatistics node, Map<String,CommunicationSummaryStatistics> nodeMap, List<String> usedIds) This method recursively builds the communication summary tree, using the supplied node map, taking copies of each node to ensure the original list is not modified as some of the nodes may be shared between multiple trees.

Method Detail

buildCommunicationSummaryTree

public static Collection<CommunicationSummaryStatistics> buildCommunicationSummaryTree(Collection<CommunicationSummaryStatistics> nodes)

This method returns the supplied list of flat nodes as a set of tree structures with related nodes.

Parameters:

nodes - The collection of nodes represented as a flat list

Returns:

The nodes returns as a collection of independent tree structures

initCommunicationSummaryTreeNode

protected static void initCommunicationSummaryTreeNode(CommunicationSummaryStatistics node,
                                                       Map<String,CommunicationSummaryStatistics> nodeMap,
                                                       List<String> usedIds)

This method recursively builds the communication summary tree, using the supplied node map, taking copies of each node to ensure the original list is not modified as some of the nodes may be shared between multiple trees. If a node is add to the tree, its id will be added to the 'used' list, to ensure that repetitions are only handled by a link (not including the sub-tree multiple times).

Parameters:

node - The current node

nodeMap - The map of possible nodes

usedIds - The list of node ids already included in the tree

getRootCommunicationSummaryNodes

protected static Collection<CommunicationSummaryStatistics> getRootCommunicationSummaryNodes(Map<String,CommunicationSummaryStatistics> nodeMap)

This method returns the subset of supplied nodes that are root nodes.

Parameters:

nodeMap - The map of all nodes

Returns:

The list of root nodes
