lookup()

std::optional< Ledger > xrpl::test::csf::LedgerOracle::lookup ( Ledger::ID const & id ) const

nodiscard

Find the ledger with the given ID.

Definition at line 124 of file ledgers.cpp.

accept() [1/2]

Ledger xrpl::test::csf::LedgerOracle::accept	(	Ledger const &	curr,
		TxSetType const &	txs,
		NetClock::duration	closeTimeResolution,
		NetClock::time_point const &	consensusCloseTime )

Accept the given txs and generate a new ledger.

Parameters

curr	The current ledger
txs	The transactions to apply to the current ledger
closeTimeResolution	Resolution used in determining close time
consensusCloseTime	The consensus agreed close time, no valid time if 0

accept() [2/2]

Ledger xrpl::test::csf::LedgerOracle::accept	(	Ledger const &	curr,
		Tx	tx )

branches()

std::size_t xrpl::test::csf::LedgerOracle::branches ( std::set< Ledger > const & ledgers )

static

Determine the number of distinct branches for the set of ledgers.

Ledgers A and B are on different branches if A != B, A is not an ancestor of B and B is not an ancestor of A, e.g.

/--> A O --> B
