getUnionOfAllGraphs

public AGGraph getUnionOfAllGraphs()

Returns the union of all graphs (includes default graph). Add operations on this graph are housed in the default graph.

Returns:

the union of all graphs.

createUnion

public AGGraphUnion createUnion(AGGraph... graphs)

Returns a graph that is the union of specified graphs. By convention, the first graph mentioned will be used for add operations on the union. All other operations will apply to all graphs in the union. If no graphs are supplied, the union of all graphs is assumed, and add operations apply to the default graph.

Parameters:

graphs - the graphs in the union

Returns:

the union of the specified graphs
