Constructor Detail

AmazonWebServiceClient

public AmazonWebServiceClient(ClientConfiguration clientConfiguration)

Constructs a new AmazonWebServiceClient object using the specified configuration.

Parameters:

clientConfiguration - The client configuration for this client.

Method Detail

setEndpoint

public void setEndpoint(String endpoint)
                 throws IllegalArgumentException

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

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.

Throws:

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

setConfiguration

public void setConfiguration(ClientConfiguration clientConfiguration)

shutdown

public void shutdown()

Shuts down this 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 should not be used to make any more requests.

addRequestHandler

public void addRequestHandler(RequestHandler requestHandler)

Appends a request handler to the list of registered handlers that are run as part of a request's lifecycle.

Parameters:

requestHandler - The new handler to add to the current list of request handlers.

removeRequestHandler

public void removeRequestHandler(RequestHandler requestHandler)

Removes a request handler from the list of registered handlers that are run as part of a request's lifecycle.

Parameters:

requestHandler - The handler to remove from the current list of request handlers.
