MakeTxGraph()

std::unique_ptr< TxGraph > MakeTxGraph ( unsigned max_cluster_count, uint64_t max_cluster_size, uint64_t acceptable_cost, const std::function< std::strong_ordering(const TxGraph::Ref &, const TxGraph::Ref &)> & fallback_order )

noexcept

Construct a new TxGraph with the specified limit on the number of transactions within a cluster, and on the sum of transaction sizes within a cluster.

• max_cluster_count cannot exceed MAX_CLUSTER_COUNT_LIMIT.
• acceptable_cost controls how much linearization optimization work will be performed per cluster before they are considered to be of acceptable quality.
• fallback_order determines how to break tie-breaks between transactions: fallback_order(a, b) < 0 means a is "better" than b, and will (in case of ties) be placed first. This ordering must be stable over the transactions' lifetimes.
