- io.opentelemetry.context.propagation.DefaultContextPropagators

All Implemented Interfaces:

ContextPropagators
```
final class DefaultContextPropagators
extends java.lang.Object
implements ContextPropagators
```
DefaultContextPropagators is the default, built-in implementation of ContextPropagators.
All the registered propagators are stored internally as a simple list, and are invoked synchronically upon injection and extraction.
The propagation fields retrieved from all registered propagators are de-duplicated.
