effectiveMembership

public OPMGraph effectiveMembership(OPMGraph g)

Returns a graph with the same structure, in which the * effective membership of all nodes has been computed. The function returns an entirely new graph, without modifying the original.

accountMembership

public Accounts accountMembership(ArtifactRef aid,
                                  OPMGraph g)

view

public OPMGraph view(OPMGraph g,
                     Accounts accs)

legalAccount

public boolean legalAccount(OPMGraph g)

intersection

public OPMGraph intersection(OPMGraph g1,
                             OPMGraph g2)
