void xrpl::OrderBookDBImpl::setup ( std::shared_ptr< ReadView const > const & ledger )

overridevirtual

Initialize or update the order book database with a new ledger.

This method should be called when a new ledger is accepted to update the order book database with the current state of all order books.

Parameters

ledger

The ledger to scan for order books

Implements xrpl::OrderBookDB.

getBooksByTakerPays()

std::vector< Book > xrpl::OrderBookDBImpl::getBooksByTakerPays ( Asset const & asset, std::optional< Domain > const & domain = std::nullopt )

overridevirtual

Get all order books that want a specific issue.

Returns a list of all order books where the taker pays the specified issue. This is useful for pathfinding to find all possible next hops from a given currency.

Parameters

asset	The asset to search for
domain	Optional domain restriction for the order book

Returns

Vector of books that want this issue

Implements xrpl::OrderBookDB.

getBookSize()

int xrpl::OrderBookDBImpl::getBookSize ( Asset const & asset, std::optional< Domain > const & domain = std::nullopt )

overridevirtual

Get the count of order books that want a specific issue.

Parameters

asset	The asset to search for
domain	Optional domain restriction for the order book

Returns

Number of books that want this issue

Implements xrpl::OrderBookDB.

Definition at line 281 of file OrderBookDBImpl.cpp.

isBookToXRP()

bool xrpl::OrderBookDBImpl::isBookToXRP ( Asset const & asset, std::optional< Domain > const & domain = std::nullopt )

overridevirtual

Check if an order book to XRP exists for the given issue.

Parameters

asset	The asset to check
domain	Optional domain restriction for the order book

Returns

true if a book from this issue to XRP exists

Implements xrpl::OrderBookDB.
