# update(_:with:eventHandler:)

Updates a transformer with a new sequence of examples.

## Declaration

```swift
func update<InputSequence, FeatureSequence>(_ transformer: inout PreprocessingUpdatableSupervisedTemporalEstimator<Preprocessor, Estimator>.Transformer, with input: InputSequence, eventHandler: EventHandler? = nil) async throws where InputSequence : Sequence, FeatureSequence : TemporalSequence, Preprocessor.Input == FeatureSequence.Feature, InputSequence.Element == AnnotatedFeature<FeatureSequence, Estimator.Annotation>
```

## Parameters

- `transformer`: A transformer to update.
- `input`: A sequence of examples.
- `eventHandler`: An event handler.
