- akka.stream.SystemMaterializer$

All Implemented Interfaces:

ExtensionId<SystemMaterializer>, ExtensionIdProvider
```
public class SystemMaterializer$
extends java.lang.Object
implements ExtensionId<SystemMaterializer>, ExtensionIdProvider
```
The system materializer is a default materializer to use for most cases running streams, it is a single instance per actor system that is tied to the lifecycle of that system.
Not intended to be manually used in user code.
