Detailed Description

template<class Peer>
class ripple::test::csf::TrustGraph< Peer >

Trust graph.

Trust is a directed relationship from a node i to node j. If node i trusts node j, then node i has node j in its UNL. This class wraps a digraph representing the trust relationships for all peers in the simulation.
