@Generated(value="OracleSDKGenerator", comments="API Version: 20180418") public class StreamAsyncClient extends Object implements StreamAsync
Async client implementation for Stream service.
There are two ways to use async client: 1. Use AsyncHandler: using AsyncHandler, if the response to the call is an InputStream
, like getObject Api in object storage service, developers need to process the stream in AsyncHandler, and not anywhere else, because the stream will be closed right after the AsyncHandler is invoked.
2. Use Java Future: using Java Future, developers need to close the stream after they are done with the Java Future.
Accessing the result should be done in a mutually exclusive manner, either through the Future or the AsyncHandler, but not both. If the Future is used, the caller should pass in null as the AsyncHandler. If the AsyncHandler is used, it is still safe to use the Future to determine whether or not the request was completed via Future.isDone/isCancelled.

public void setEndpoint(String endpoint)
StreamAsync
Sets the endpoint to call (ex, https://www.example.com).

in interface StreamAsync
endpoint
- The endpoint of the serice.public void setRegion(Region region)
StreamAsync
Sets the region to call (ex, Region.US_PHOENIX_1).
Note, this will call setEndpoint
after resolving the endpoint. If the service is not available in this region, however, an IllegalArgumentException will be raised.
setRegion
in interface StreamAsync
region
- The region of the service.public void setRegion(String regionId)
StreamAsync
Sets the region to call (ex, ‘us-phoenix-1’).
Note, this will first try to map the region ID to a known Region and call setRegion
.
If no known Region could be determined, it will create an endpoint based on the default endpoint format (Region.formatDefaultRegionEndpoint(Service, String)
and then call setEndpoint
.

public Future<ConsumerCommitResponse> consumerCommit(ConsumerCommitRequest request, AsyncHandler<ConsumerCommitRequest,ConsumerCommitResponse> handler)
StreamAsync
Provides a mechanism to manually commit offsets, if not using commit-on-get consumer semantics. This commits offsets assicated with the provided cursor, extends the timeout on each of the affected partitions, and returns an updated cursor.

request
- The request object containing the details to sendhandler
- The request handler to invoke upon completion, may be null.public Future<ConsumerHeartbeatResponse> consumerHeartbeat(ConsumerHeartbeatRequest request, AsyncHandler<ConsumerHeartbeatRequest,ConsumerHeartbeatResponse> handler)

request
- The request object containing the details to sendhandler
- The request handler to invoke upon completion, may be null.public Future<CreateCursorResponse> createCursor(CreateCursorRequest request, AsyncHandler<CreateCursorRequest,CreateCursorResponse> handler)
StreamAsync
Creates a cursor. Cursors are used to consume a stream, starting from a specific point in the partition and going forward from there. You can create a cursor based on an offset, a time, the trim horizon, or the most recent message in the stream. As the oldest message inside the retention period boundary, using the trim horizon effectively lets you consume all messages in the stream. A cursor based on the most recent message allows consumption of only messages that are added to the stream after you create the cursor. Cursors expire five minutes after you receive them from the service.

request
- The request object containing the details to sendhandler
- The request handler to invoke upon completion, may be null.public Future<GetMessagesResponse> getMessages(GetMessagesRequest request, AsyncHandler<GetMessagesRequest,GetMessagesResponse> handler)
StreamAsync
Returns messages from the specified stream using the specified cursor as the starting point for consumption. By default, the number of messages returned is undefined, but the service returns as many as possible. To get messages, you must first obtain a cursor using the createCursor
operation. In the response, retrieve the value of the ‘opc-next-cursor’ header to pass as a parameter to get the next batch of messages in the stream.

in interface StreamAsync
request
- The request object containing the details to sendhandler
- The request handler to invoke upon completion, may be null.public Future<PutMessagesResponse> putMessages(PutMessagesRequest request, AsyncHandler<PutMessagesRequest,PutMessagesResponse> handler)
StreamAsync
Emits messages to a stream. There’s no limit to the number of messages in a request, but the total size of a message or request must be 1 MiB or less. The service calculates the partition ID from the message key and stores messages that share a key on the same partition. If a message does not contain a key or if the key is null, the service generates a message key for you. The partition ID cannot be passed as a parameter.
