visitEntry()

void xrpl::ValidMPTTransfer::visitEntry	(	bool	isDelete,
		std::shared_ptr< SLE const > const &	before,
		std::shared_ptr< SLE const > const &	after )

Track MPT balance changes and deleted authorization state.

Parameters

isDelete	Whether the ledger entry is being deleted.
before	The ledger entry before transaction application.
after	The ledger entry after transaction application.

Definition at line 774 of file MPTInvariant.cpp.

finalize()

bool xrpl::ValidMPTTransfer::finalize	(	STTx const &	tx,
		TER const	result,
		XRPAmount const	fee,
		ReadView const &	view,
		beast::Journal const &	j )

Verify MPT transfer authorization invariants.

Parameters

tx	The transaction being checked.
result	The transaction result code.
fee	The fee charged by the transaction.
view	The ledger view after transaction application.
j	Journal used for diagnostics.

Returns

true if the invariant checks pass, otherwise false.

Definition at line 833 of file MPTInvariant.cpp.

isAuthorized()

bool xrpl::ValidMPTTransfer::isAuthorized ( ReadView const & view, MPTID const & mptid, AccountID const & holder, bool requireAuth ) const

nodiscardprivate

Check whether a holder is authorized to send or receive an MPToken.

Deleted MPToken SLEs are no longer present in the view by the time finalize() runs, so their authorization state is captured during visitEntry() and stored in deletedAuthorized_. For deleted MPTokens, returns true if reqAuth is false or lsfMPTAuthorized was set at deletion. For existing MPTokens, returns the result of requireAuth().

Parameters

view	The ledger view after transaction application.
mptid	The MPToken issuance ID.
holder	The holder account being checked.
requireAuth	Whether the issuance requires explicit authorization.

Returns

true if the holder is authorized, otherwise false.
