Method Detail

createUnionGraph

public static CyNetwork createUnionGraph(List networkList,
                                         boolean copyView,
                                         String title)

Create a new graph which is the union of multiple graphs. The union graph is created by applying the set union on both the edges and the nodes.

Parameters:

networkList - A list containing all of the networks.

copyView - Flag indicates whether view information should be copied to the new view

title - The title of the new network

Returns:

A cyNetwork which is the union of the input graphs

createIntersectionGraph

public static CyNetwork createIntersectionGraph(List networkList,
                                                boolean copyView,
                                                String title)

Create a new graph which is the intersection of multiple graphs. The intersection graph is created by applying the set intersection on both the edges and the nodes.

Parameters:

networkList - A list containing all of the networks.

copyView - Flag indicates whether view information should be copied to the new view

title - The title of the new network

Returns:

A cyNetwork which is the intersection of the input graphs

createDifferenceGraph

public static CyNetwork createDifferenceGraph(List networkList,
                                              boolean copyView,
                                              String title)

Create a new graph which is the difference of multiple graphs. Note that this is not the symmetric difference. The second graph in the list (and the third and the fourth ... ) are subtracted from the first graph. Here, we can not directly apply the set difference on the nodes and edge sets and get a valid graph. Therefore, we apply the difference operation on the edge sets firsts and add those nodes in the node difference set which are required for those edges to exist.

Parameters:

networkList - A list containing all of the networks.

copyView - Flag indicates whether view information should be copied to the new view

title - The title of the new network

Returns:

A cyNetwork which is the difference of the input graphs
