DataPropagationProvider (Helidon Project 2.6.9 API)

Type Parameters:

T - an actual type of the data which will be propagated

All Known Implementing Classes:

JaegerDataPropagationProvider, JulMdcPropagator, Slf4jMdcPropagator
```
public interface DataPropagationProvider<T>
```
This is an SPI provider which helps user to propagate values from one thread to another. Every provider has its method data() invoked before thread switch, to obtain value for propagation. After the thread is switched, the new thread executes propagateData(Object) to propagate data.
