setEndpoint

public void setEndpoint(String endpoint)

Description copied from class: AmazonWebServiceClient

Overrides the default endpoint for this client. Callers can use this method to control which AWS region they want to work with.

This method is not threadsafe. Endpoints should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit.

Callers can pass in just the endpoint (ex: "ec2.amazonaws.com") or a full URL, including the protocol (ex: "https://ec2.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912

Specified by:

setEndpoint in interface AWSLogs

Overrides:

setEndpoint in class AmazonWebServiceClient

Parameters:

endpoint - The endpoint (ex: "ec2.amazonaws.com") or a full URL, including the protocol (ex: "https://ec2.amazonaws.com") of the region specific AWS endpoint this client will communicate with.

setEndpoint

public void setEndpoint(String endpoint,
               String serviceName,
               String regionId)
                 throws IllegalArgumentException

Description copied from class: AmazonWebServiceClient

An internal method that is not expected to be normally called except for AWS internal development purposes.

Overrides the default endpoint for this client ("http://dynamodb.us-east-1.amazonaws.com/") and explicitly provides an AWS region ID and AWS service name to use when the client calculates a signature for requests. In almost all cases, this region ID and service name are automatically determined from the endpoint, and callers should use the simpler one-argument form of setEndpoint instead of this method.

Callers can pass in just the endpoint (ex: "dynamodb.us-east-1.amazonaws.com/") or a full URL, including the protocol (ex: "http://dynamodb.us-east-1.amazonaws.com/"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912

Overrides:

setEndpoint in class AmazonWebServiceClient

Parameters:

endpoint - The endpoint (ex: "dynamodb.us-east-1.amazonaws.com/") or a full URL, including the protocol (ex: "http://dynamodb.us-east-1.amazonaws.com/") of the region specific AWS endpoint this client will communicate with.

serviceName - This parameter is ignored.

regionId - The ID of the region in which this service resides AND the overriding region for signing purposes.

Throws:

IllegalArgumentException - If any problems are detected with the specified endpoint.

getCachedResponseMetadata

public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

Specified by:

getCachedResponseMetadata in interface AWSLogs

Parameters:

request - The originally executed request

Returns:

The response metadata for the specified request, or null if none is available.
