public abstract class BidiStreamingCallable<RequestT,ResponseT>

A BidiStreamingCallable is an immutable object which is capable of making RPC calls to bidirectional streaming API methods. Not all transports support streaming.

It is considered advanced usage for a user to create a BidiStreamingCallable themselves. This class is intended to be created by a generated client class, and configured by instances of StreamingCallSettings.Builder which are exposed through the client settings class.

Methods

bidiStreamingCall(ApiStreamObserver<ResponseT> responseObserver) (deprecated)

public ApiStreamObserver<RequestT> bidiStreamingCall(ApiStreamObserver<ResponseT> responseObserver)

(deprecated) Please use #splitCall(ResponseObserver) instead.

Conduct a bidirectional streaming call

Parameter

Name	Description
responseObserver	ApiStreamObserver<ResponseT> ApiStreamObserver to observe the streaming responses

Returns

Type	Description
ApiStreamObserver<RequestT>	ApiStreamObserver which is used for making streaming requests.

bidiStreamingCall(ApiStreamObserver<ResponseT> responseObserver, ApiCallContext context) (deprecated)

public ApiStreamObserver<RequestT> bidiStreamingCall(ApiStreamObserver<ResponseT> responseObserver, ApiCallContext context)

(deprecated) Please use #splitCall(ResponseObserver, ApiCallContext) instead.

Conduct a bidirectional streaming call with the given ApiCallContext.

Parameters

Name	Description
responseObserver	ApiStreamObserver<ResponseT> ApiStreamObserver to observe the streaming responses
context	ApiCallContext ApiCallContext to provide context information for the RPC call.

Returns

Type	Description
ApiStreamObserver<RequestT>	ApiStreamObserver which is used for making streaming requests.

call()

public BidiStream<RequestT,ResponseT> call()

Send requests and iterate over server responses.

This returns a live stream that must either be fully consumed or cancelled. Example usage:

 BidiStream

Returns

Type	Description
BidiStream<RequestT,ResponseT>

call(ApiCallContext context)

public BidiStream<RequestT,ResponseT> call(ApiCallContext context)

Send requests and iterate over server responses.

This returns a live stream that must either be fully consumed or cancelled.

Parameter

Name	Description
context	ApiCallContext

Returns

Type	Description
BidiStream<RequestT,ResponseT>

call(BidiStreamObserver<RequestT,ResponseT> bidiObserver)

public void call(BidiStreamObserver<RequestT,ResponseT> bidiObserver)

Listens to server responses and send requests when the network is free. Example usage:

 final Iterator

Parameter

Name	Description
bidiObserver	BidiStreamObserver<RequestT,ResponseT>

call(BidiStreamObserver<RequestT,ResponseT> bidiObserver, ApiCallContext context)

public void call(BidiStreamObserver<RequestT,ResponseT> bidiObserver, ApiCallContext context)

Listens to server responses and send requests when the network is free.

Parameters

Name	Description
bidiObserver	BidiStreamObserver<RequestT,ResponseT>
context	ApiCallContext

internalCall(ResponseObserver<ResponseT> responseObserver, ClientStreamReadyObserver<RequestT> onReady, ApiCallContext context)

public abstract ClientStream<RequestT> internalCall(ResponseObserver<ResponseT> responseObserver, ClientStreamReadyObserver<RequestT> onReady, ApiCallContext context)

The "base" method from which other forms of calls are derived. Most users will not need to call this method directly.

However, it is public, since library authors might want to call this method in adaptor classes.

Parameters

Name	Description
responseObserver	ResponseObserver<ResponseT>
onReady	ClientStreamReadyObserver<RequestT>
context	ApiCallContext

Returns

Type	Description
ClientStream<RequestT>

splitCall(ResponseObserver<ResponseT> responseObserver)

public ClientStream<RequestT> splitCall(ResponseObserver<ResponseT> responseObserver)

Send requests to the server and listens to responses.

Example usage:

 ResponseObserver

Parameter

Name	Description
responseObserver	ResponseObserver<ResponseT>

Returns

Type	Description
ClientStream<RequestT>

splitCall(ResponseObserver<ResponseT> responseObserver, ApiCallContext context)

public ClientStream<RequestT> splitCall(ResponseObserver<ResponseT> responseObserver, ApiCallContext context)

Send requests to the server and listens to responses.

Parameters

Name	Description
responseObserver	ResponseObserver<ResponseT>
context	ApiCallContext

Returns

Type	Description
ClientStream<RequestT>

withDefaultCallContext(ApiCallContext defaultCallContext)

public BidiStreamingCallable<RequestT,ResponseT> withDefaultCallContext(ApiCallContext defaultCallContext)

Returns a new BidiStreamingCallable with an ApiCallContext that is used as a default when none is supplied in individual calls.

Parameter

Name	Description
defaultCallContext	ApiCallContext the default ApiCallContext.

Returns

Type	Description
BidiStreamingCallable<RequestT,ResponseT>
