Transactor

suspend fun inTransaction(): Boolean

Returns true if this connection has an active transaction, otherwise false.

suspend fun <R : Any?> withTransaction(
    type: Transactor.SQLiteTransactionType,
    block: suspend TransactionScope<R>.() -> R
): R

Begins a transaction and runs the block within the transaction. If block fails to complete normally i.e., an exception is thrown, or TransactionScope.rollback is invoked then the transaction will be rollback, otherwise it is committed.

If inTransaction returns true and this function is invoked it is the equivalent of starting a nested transaction as if TransactionScope.withNestedTransaction was invoked and the type of the transaction will be ignored since its type will be inherited from the parent transaction.

suspend fun <R : Any?> Transactor.deferredTransaction(block: suspend TransactionScope<R>.() -> R): R

suspend fun <R : Any?> Transactor.exclusiveTransaction(block: suspend TransactionScope<R>.() -> R): R

Performs a SQLiteTransactionType.EXCLUSIVE within the block.

suspend fun <R : Any?> Transactor.immediateTransaction(block: suspend TransactionScope<R>.() -> R): R

Performs a SQLiteTransactionType.IMMEDIATE within the block.
