```
public class Null
extends AbstractSink
```
Actor that gobbles up all tokens, like '/dev/null' in Unix.

Input/output:
- accepts:
```
   adams.flow.core.Unknown
```
Valid options are:
```
-D (property: debug)
         If set to true, scheme may output additional info to the console.
 
```
```
-name <java.lang.String> (property: name)
         The name of the actor.
         default: Null
 
```
```
-annotation <adams.core.base.BaseString> [-annotation ...] (property: annotations)
         The annotations to attach to this actor.
 
```
```
-skip (property: skip)
         If set to true, transformation is skipped and the input token is just forwarded
          as it is.
