Method Detail

unmutableGraph

public static Graph unmutableGraph(Graph g)

synchronizedGraph

public static Graph synchronizedGraph(Graph g)

Synchronizes a graph. The returned graph can be accessed and modified by several threads. You lose genericity in methods returning edge or node because each element (graph, nodes and edges) is wrapped into a synchronized wrapper which breaks original elements class.

Parameters:

g - the graph to synchronize

Returns:

a synchronized wrapper for g

merge

public static Graph merge(Graph... graphs)

Merge several graphs in one. A new graph is created, that will contain the result. The method will try to create a graph of the same class that the first graph to merge (it needs to have a constructor with a String). Else, a MultiGraph is used.

Parameters:

graphs - graphs to merge

Returns:

merge result

mergeIn

public static void mergeIn(Graph result,
           Graph... graphs)

Merge several graphs in one. The first parameter is the graph in which the other graphs will be merged.

Parameters:

result - destination graph.

graphs - all graphs that will be merged in result.

clone

public static Graph clone(Graph g)

Clone a given graph with same node/edge structure and same attributes.

Parameters:

g - the graph to clone

Returns:

a copy of g

copyAttributes

public static void copyAttributes(Element source,
                  Element target)

Parameters:

source -

target -
