◆ visitInvariantEntry()

void xrpl::VaultDeposit::visitInvariantEntry ( bool isDelete,
SLE::const_ref before,
SLE::const_ref after )
overridevirtual

Inspect a single ledger entry modified by this transaction.

Called once for every SLE created, modified, or deleted by the transaction, before finalizeInvariants. Implementations should accumulate whatever state they need to verify transaction-specific post-conditions.

Parameters
isDeletetrue if the entry was erased from the ledger.
beforethe entry's state before the transaction (nullptr for newly created entries).
afterthe entry's state as supplied by the apply logic for this transaction. For deletions, this is the SLE being erased and is not guaranteed to be null; callers must use isDelete rather than after == nullptr to detect deletions.

Implements xrpl::Transactor.

◆ finalizeInvariants()

nodiscardoverridevirtual

Check transaction-specific post-conditions after all entries have been visited.

Called once after every modified ledger entry has been passed to visitInvariantEntry. Returns true if all transaction-specific invariants hold, or false to fail the transaction with tecINVARIANT_FAILED.

Parameters
txthe transaction being applied.
resultthe tentative TER result so far.
feethe fee consumed by the transaction.
viewread-only view of the ledger after the transaction.
jjournal for logging invariant failures.
Returns
true if all invariants pass; false otherwise.

◆ checkInvariants()

TER xrpl::Transactor::checkInvariants ( TER result,

nodiscardinherited

Check all invariants for the current transaction.

Runs transaction-specific invariants first (visitInvariantEntry + finalizeInvariants), then protocol-level invariants. Both layers always run; the worst failure code is returned.

Parameters
resultthe tentative TER from transaction processing.
feethe fee consumed by the transaction.
Returns
the final TER after all invariant checks.

◆ checkGranularSemantics()

NotTEC xrpl::Transactor::checkGranularSemantics ( ReadView const & view,
STTx const & tx,
std::unordered_set< GranularPermissionType > const & heldGranularPermissions )
staticinherited

This function can be overridden to introduce additional semantic constraints beyond the granular template validation for granular permissions.

It is called by the base invokeCheckPermission method only after the transaction has successfully passed checkGranularSandbox.

Definition at line 238 of file Transactor.h.

◆ invokeCheckPermission()

template<class T>
NotTEC xrpl::Transactor::invokeCheckPermission ( ReadView const & view,
STTx const & tx )
staticinherited

Checks whether the transaction is authorized to be executed by the delegated account.

This function enforces the strict permission check hierarchy. It is explicitly designed NOT to be overridden. Derived transactors must instead implement checkGranularSemantics to add custom validation logic for granular permissions.

The evaluation proceeds as follows:

  • If transaction-level permission is granted, the function immediately returns tesSUCCESS.
  • If transaction-level permission is not granted, the function checks whether the transaction matches the granular permission template defined in permissions.macro. If it does, it then calls checkGranularSemantics to perform any additional, fine-grained validation.
