DataEndpoint<T>
DataStreams	DataStreams.DataStreamDecoder treats multiple ByteStrings as a single input stream decoding values with the supplied iterator.
DataStreams.DataStreamDecoder<T>	An adapter which converts an InputStream to a PrefetchableIterator of T values using the specified Coder.
DataStreams.ElementDelimitedOutputStream	An adapter which wraps an DataStreams.OutputChunkConsumer as an OutputStream.
DataStreams.OutputChunkConsumer<T>	A callback which is invoked whenever the DataStreams.outbound(org.apache.beam.sdk.fn.stream.DataStreams.OutputChunkConsumer<org.apache.beam.vendor.grpc.v1p48p1.com.google.protobuf.ByteString>) OutputStream becomes full.
DecodingFnDataReceiver<T>	A receiver of encoded data, decoding it and passing it onto a downstream consumer.
DirectStreamObserver<T>	A StreamObserver which uses synchronization on the underlying CallStreamObserver to provide thread safety.
EncodedBoundedWindow	An encoded BoundedWindow used within Runners to track window information without needing to decode the window.
EncodedBoundedWindow.Coder	An EncodedBoundedWindow.Coder for EncodedBoundedWindows.
FnDataReceiver<T>	A receiver of streamed data.
FnService	An interface sharing common behavior with services used during execution of user Fns.
ForwardingClientResponseObserver<ReqT,RespT>	A ClientResponseObserver which delegates all StreamObserver calls.

JvmInitializers	Helpers for executing JvmInitializer implementations.
LogicalEndpoint	A logical endpoint is a pair of an instruction ID corresponding to the BeamFnApi.ProcessBundleRequest and the transform within the processing graph.
ManagedChannelFactory	A Factory which creates ManagedChannel instances.
OutboundObserverFactory	Creates factories which determine an underlying StreamObserver implementation to use in to interact with fn execution APIs.
OutboundObserverFactory.BasicFactory<ReqT,RespT>	Creates an outbound observer for the given inbound observer.
PrefetchableIterable<T>	An Iterable that returns PrefetchableIterators.
PrefetchableIterables	This class contains static utility functions that operate on or return objects of type PrefetchableIterable.
PrefetchableIterables.Default<T>	A default implementation that caches an iterator to be returned when PrefetchableIterables.Default.prefetch() is invoked.
PrefetchableIterator<T>	Iterator that supports prefetching the next set of records.
PrefetchableIterators
RemoteGrpcPortRead	An execution-time only RunnerApi.PTransform which represents an SDK harness reading from a BeamFnApi.RemoteGrpcPort.
RemoteGrpcPortWrite	An execution-time only RunnerApi.PTransform which represents a write from within an SDK harness to a BeamFnApi.RemoteGrpcPort.
RestrictionTrackers	Support utilities for interacting with RestrictionTrackers.
RestrictionTrackers.ClaimObserver<PositionT>	Interface allowing a runner to observe the calls to RestrictionTracker.tryClaim(PositionT).
ServerFactory	A gRPC server factory.
ServerFactory.InetSocketAddressServerFactory	Creates a gRPC Server using the default server factory.
ServerFactory.UrlFactory	Factory that constructs client-accessible URLs from a local server address and port.
SocketAddressFactory	Creates a SocketAddress based upon a supplied string.
SynchronizedStreamObserver<V>	A StreamObserver which provides synchronous access access to an underlying StreamObserver.
