From source file:org.apache.http.impl.client.cache.CachingHttpClient.java

public <T> T execute(HttpHost target, HttpRequest request, ResponseHandler<? extends T> responseHandler,
        HttpContext context) throws IOException {
    HttpResponse resp = execute(target, request, context);
    return responseHandler.handleResponse(resp);
}

}

From source file:org.apache.http.impl.client.CloseableHttpClient.java

/**
 * Executes a request using the default context and processes the
 * response using the given response handler. The content entity associated
 * with the response is fully consumed and the underlying connection is
 * released back to the connection manager automatically in all cases
 * relieving individual {@link ResponseHandler}s from having to manage
 * resource deallocation internally.//from w  w  w  .  ja  v a  2 s .  c  om
 *
 * @param target    the target host for the request.
 *                  Implementations may accept <code>null</code>
 *                  if they can still determine a route, for example
 *                  to a default target or by inspecting the request.
 * @param request   the request to execute
 * @param responseHandler the response handler
 * @param context   the context to use for the execution, or
 *                  <code>null</code> to use the default context
 *
 * @return  the response object as generated by the response handler.
 * @throws IOException in case of a problem or the connection was aborted
 * @throws ClientProtocolException in case of an http protocol error
