All Superinterfaces:

AsyncCloseable, AutoCloseable, GracefulAutoCloseable, HttpRequester, HttpRequestFactory, ListenableAsyncCloseable

public interface HttpClient
extends HttpRequester, GracefulAutoCloseable

Provides a means to issue requests against HTTP service. The implementation is free to maintain a collection of HttpConnection instances and distribute calls to request(HttpRequest) amongst this collection.

Method Detail

request

Single<HttpResponse> request(HttpRequest request)

Send a request.

Parameters:

request - the request to send.

Returns:

The response.

reserveConnection

Single<ReservedHttpConnection> reserveConnection(HttpRequestMetaData metaData)

Reserve an HttpConnection based on provided HttpRequestMetaData.

Parameters:

metaData - Allows the underlying layers to know what HttpConnections are valid to reserve for future requests with the same HttpRequestMetaData. For example this may provide some insight into shard or other info.

Returns:

a Single that provides the ReservedHttpConnection upon completion.

reserveConnection

Single<ReservedHttpConnection> reserveConnection(HttpExecutionStrategy strategy,
                                                 HttpRequestMetaData metaData)

Reserve an HttpConnection based on provided HttpRequestMetaData.

Note: reserved connections may not be restricted by the max pipelined requests count.

Parameters:

strategy - HttpExecutionStrategy to use.

metaData - Allows the underlying layers to know what HttpConnections are valid to reserve for future requests with the same HttpRequestMetaData. For example this may provide some insight into shard or other info.

Returns:

a Single that provides the ReservedHttpConnection upon completion.

asStreamingClient

StreamingHttpClient asStreamingClient()

Convert this HttpClient to the StreamingHttpClient API.

Returns:

a StreamingHttpClient representation of this HttpClient.

asBlockingStreamingClient

default BlockingStreamingHttpClient asBlockingStreamingClient()

Convert this HttpClient to the BlockingStreamingHttpClient API.

Returns:

a BlockingStreamingHttpClient representation of this HttpClient.

asBlockingClient

default BlockingHttpClient asBlockingClient()

Convert this HttpClient to the BlockingHttpClient API.

Returns:

a BlockingHttpClient representation of this HttpClient.
