DirectStreamObserver (fn-execution 2.44.0 API)

java.lang.Object
- org.apache.beam.sdk.fn.stream.DirectStreamObserver<T>

All Implemented Interfaces:

org.apache.beam.vendor.grpc.v1p48p1.io.grpc.stub.StreamObserver<T>
```
@ThreadSafe
public final class DirectStreamObserver<T>
extends java.lang.Object
implements org.apache.beam.vendor.grpc.v1p48p1.io.grpc.stub.StreamObserver<T>
```
A StreamObserver which uses synchronization on the underlying CallStreamObserver to provide thread safety.
Flow control with the underlying CallStreamObserver is handled with a Phaser which waits for advancement of the phase if the CallStreamObserver is not ready. Creator is expected to advance the Phaser whenever the underlying CallStreamObserver becomes ready.
