Annotation Type SystemDoFnInternal

@Documented
 @Retention(value=RUNTIME)
 @Target(value=TYPE)
public @interface SystemDoFnInternal

Annotation to mark DoFns as an internal component of the Dataflow SDK.

Currently, the only effect of this is to mark any aggregators reported by an annotated DoFn as a system counter (as opposed to a user counter).

This is internal to the Dataflow SDK.
