Interface HttpClient

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 Summary

default BlockingHttpClient	asBlockingClient() Convert this HttpClient to the BlockingHttpClient API.
default BlockingStreamingHttpClient	asBlockingStreamingClient() Convert this HttpClient to the BlockingStreamingHttpClient API.
StreamingHttpClient	asStreamingClient() Convert this HttpClient to the StreamingHttpClient API.
default void	close()
default void	closeGracefully()
Single<HttpResponse>	request(HttpRequest request) Send a request.
default Single<ReservedHttpConnection>	reserveConnection(HttpExecutionStrategy strategy, HttpRequestMetaData metaData) Deprecated. Use reserveConnection(HttpRequestMetaData). If an HttpExecutionStrategy needs to be altered, provide a value for HttpContextKeys.HTTP_EXECUTION_STRATEGY_KEY in the request context.

Method Detail

request

Single<HttpResponse> request(HttpRequest request)

Send a request.

Specified by:

request in interface HttpRequester

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

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

Deprecated. Use reserveConnection(HttpRequestMetaData). If an HttpExecutionStrategy needs to be altered, provide a value for HttpContextKeys.HTTP_EXECUTION_STRATEGY_KEY in the request context.

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.

close

default void close()
            throws Exception

Specified by:

close in interface AutoCloseable

Throws:

Exception

closeGracefully

default void closeGracefully()
                      throws Exception

Specified by:

closeGracefully in interface GracefulAutoCloseable

Throws:

Exception
