Abstract base class for ClientHttpRequestFactory implementations that decorate another request factory.
Author:Arjen Poutsma
Since:3.1
/** * Abstract base class for {@link ClientHttpRequestFactory} implementations * that decorate another request factory. * * @author Arjen Poutsma * @since 3.1 */
public abstract class AbstractClientHttpRequestFactoryWrapper implements ClientHttpRequestFactory { private final ClientHttpRequestFactory requestFactory;
Create a AbstractClientHttpRequestFactoryWrapper wrapping the given request factory.
Params:
  • requestFactory – the request factory to be wrapped
/** * Create a {@code AbstractClientHttpRequestFactoryWrapper} wrapping the given request factory. * @param requestFactory the request factory to be wrapped */

This implementation simply calls createRequest(URI, HttpMethod, ClientHttpRequestFactory) with the wrapped request factory provided to the constructor.

@Override public final ClientHttpRequest createRequest(URI uri, HttpMethod httpMethod) throws IOException { return createRequest(uri, httpMethod, this.requestFactory); }
Create a new ClientHttpRequest for the specified URI and HTTP method by using the passed-on request factory.

Called from createRequest(URI, HttpMethod).

Params:
  • uri – the URI to create a request for
  • httpMethod – the HTTP method to execute
  • requestFactory – the wrapped request factory
Throws:
Returns:the created request
