Interface HttpClientTransport

All Superinterfaces:

ClientConnectionFactory

All Known Implementing Classes:

AbstractHttpClientTransport, HttpClientTransportOverFCGI, HttpClientTransportOverHTTP, HttpClientTransportOverHTTP2

public interface HttpClientTransport
extends ClientConnectionFactory

HttpClientTransport represents what transport implementations should provide in order to plug-in a different transport for HttpClient.

While the HttpClient APIs define the HTTP semantic (request, response, headers, etc.) how a HTTP exchange is carried over the network depends on implementations of this class.

The default implementation uses the HTTP protocol to carry over the network the HTTP exchange, but the HTTP exchange may also be carried using the FCGI protocol, the HTTP/2 protocol or, in future, other protocols.

Method Detail

setHttpClient

void setHttpClient(HttpClient client)

Sets the HttpClient instance on this transport.

This is needed because of a chicken-egg problem: in order to create the HttpClient a HttpClientTransport is needed, that therefore cannot have a reference yet to the HttpClient.

Parameters:

client - the HttpClient that uses this transport.

newHttpDestination

HttpDestination newHttpDestination(Origin origin)

Creates a new, transport-specific, HttpDestination object.

HttpDestination controls the destination-connection cardinality: protocols like HTTP have 1-N cardinality, while multiplexed protocols like HTTP/2 have a 1-1 cardinality.

Parameters:

origin - the destination origin

Returns:

a new, transport-specific, HttpDestination object

connect

void connect(InetSocketAddress address,
             Map<String,Object> context)

Establishes a physical connection to the given address.

Parameters:

address - the address to connect to

context - the context information to establish the connection
