Methods

atomicPhase_

▸ Protected atomicPhase_<TResult, TError>(work, isolationOrErrorHandler?, maybeErrorHandlerOrDontFail?): Promise<TResult>

Wraps some work within a transactional block. If the service already has a transaction manager attached this will be reused, otherwise a new transaction manager is created.

Type parameters

Name
TResult
TError

Parameters

Name	Type	Description
work	(transactionManager: EntityManager) => Promise<TResult>	the transactional work to be done
isolationOrErrorHandler?	IsolationLevel | (error: TError) => Promise<void | TResult>	the isolation level to be used for the work.
maybeErrorHandlerOrDontFail?	(error: TError) => Promise<void | TResult>	Potential error handler

Returns

Promise<TResult>

the result of the transactional work
