## 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
