Interface HttpExecuteInterceptor

All Known Implementing Classes:
BasicAuthentication
public interface HttpExecuteInterceptor
HTTP request execute interceptor to intercept the start of HttpRequest.execute() before executing the HTTP request.

For example, this might be used to sign a request for OAuth: 

 public class OAuthSigner implements HttpExecuteInterceptor {
   public void intercept(HttpRequest request) throws IOException {
     // sign request...
   }
 }

Sample usage with a request factory: 

 public static HttpRequestFactory createRequestFactory(HttpTransport transport) {
   final OAuthSigner signer = new OAuthSigner(...);
   return transport.createRequestFactory(new HttpRequestInitializer() {
     public void initialize(HttpRequest request) {
       request.setInterceptor(signer);
     }
   });
 }

More complex usage example: 

 public static HttpRequestFactory createRequestFactory2(HttpTransport transport) {
   final OAuthSigner signer = new OAuthSigner(...);
   return transport.createRequestFactory(new HttpRequestInitializer() {
     public void initialize(HttpRequest request) {
       request.setInterceptor(new HttpExecuteInterceptor() {
         public void intercept(HttpRequest request) throws IOException {
           signer.intercept(request);
         }
       });
     }
   });
 }

Implementations should normally be thread-safe.
