```
public class ActorMaterializer$
extends java.lang.Object
```
Scala API: Creates an ActorMaterializer that can materialize stream blueprints as running streams.
The required ActorRefFactory (which can be either an ActorSystem or an ActorContext) will be used to create one actor that in turn creates actors for the transformation steps.
The materializer's ActorMaterializerSettings will be obtained from the configuration of the context's underlying ActorSystem.
The namePrefix is used as the first part of the names of the actors running the processing steps. The default namePrefix is "flow". The actor names are built up of namePrefix-flowNumber-flowStepNumber-stepName.

public ActorMaterializer apply(scala.Option<ActorMaterializerSettings> materializerSettings,
                               scala.Option<java.lang.String> namePrefix,

                               ActorRefFactory context)
```
    Scala API: Creates an ActorMaterializer that can materialize stream blueprints as running streams.
    The required ActorRefFactory (which can be either an ActorSystem or an ActorContext) will be used to create these actors, therefore it is *forbidden* to pass this object to another actor if the factory is an ActorContext.
    The namePrefix is used as the first part of the names of the actors running the processing steps. The default namePrefix is "flow". The actor names are built up of namePrefix-flowNumber-flowStepNumber-stepName.
    
    Parameters:
    
    materializerSettings - (undocumented)
    
    namePrefix - (undocumented)
    
    context - (undocumented)
    
    Returns:

    Java API: Creates an ActorMaterializer that can materialize stream blueprints as running streams.
    The required ActorRefFactory (which can be either an ActorSystem or an ActorContext) will be used to create these actors, therefore it is *forbidden* to pass this object to another actor if the factory is an ActorContext.
    Defaults the actor name prefix used to name actors running the processing steps to "flow". The actor names are built up of namePrefix-flowNumber-flowStepNumber-stepName.
