Method Detail

getResponseMetadataForRequest

@Deprecated
public ResponseMetadata getResponseMetadataForRequest(AmazonWebServiceRequest request)

Deprecated. ResponseMetadata cache can hold up to 50 requests and responses in memory and will cause memory issue. This method now always returns null.

Returns additional response metadata for an executed request. Response metadata isn't considered part of the standard results returned by an operation, so it's accessed instead through this diagnostic interface. Response metadata is typically used for troubleshooting issues with AWS support staff when services aren't acting as expected.

Parameters:

request - A previously executed AmazonWebServiceRequest object, whose response metadata is desired.

Returns:

The response metadata for the specified request, otherwise null if there is no response metadata available for the request.

execute

public <T> Response<T> execute(Request<?> request,
                               HttpResponseHandler<AmazonWebServiceResponse<T>> responseHandler,
                               HttpResponseHandler<AmazonServiceException> errorResponseHandler,
                               ExecutionContext executionContext)
                        throws AmazonClientException,
                               AmazonServiceException

Executes the request and returns the result.

Parameters:

request - The AmazonWebServices request to send to the remote server

responseHandler - A response handler to accept a successful response from the remote server

errorResponseHandler - A response handler to accept an unsuccessful response from the remote server

executionContext - Additional information about the context of this web service call

Throws:

AmazonClientException

AmazonServiceException

shutdown

public void shutdown()

Shuts down this HTTP client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it cannot be used to make more requests.

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

getRequestMetricCollector

public RequestMetricCollector getRequestMetricCollector()

Returns the http client specific request metric collector; or null if there is none.
