BreadthFirstTraversalSearch

public BreadthFirstTraversalSearch(ArgumentsBundle bundle)

Public constructor for initializing the BreadthFirstTraversalSearch with default conditions.

Parameters:

bundle - the ArgumentsBundle containing the instantiation arguments.

Method Details

toString

public String toString()

Overrides:

toString in class Object

process

public ArrayList<Graph> process(Graph graph)

Processes data.
Finds most Subgraphs by performing a breadth first search on the node tree. It is unknown if it finds all or only most of the subgraphs due to the nature of the algorithm. It is expected, however, that it would miss certain node groupings.

Parameters:

graph - the Graph object to search through.

Returns:

the Graph array holding all found subgraphs.

searchNode

private Graph searchNode(Graph graph,
 Node node)

Helper method to search for the SubGraphs in Breadth First Search. Creates and manages a queue of nodes to search through. Is called on each node in the tree.

Parameters:

graph - the Graph object to search through.

node - the node to use as the root.

Returns:

the Graph object representing the found subgraph.

setComparator

private void setComparator()
