Constructor Detail

AmazonWebServiceClient

public AmazonWebServiceClient(ClientConfiguration clientConfiguration)

Constructs a new AmazonWebServiceClient object using the specified configuration.

Parameters:

clientConfiguration - The client configuration for this client.

AmazonWebServiceClient

public AmazonWebServiceClient(ClientConfiguration clientConfiguration,
                              RequestMetricCollector requestMetricCollector)

Constructs a new AmazonWebServiceClient object using the specified configuration and request metric collector.

Parameters:

clientConfiguration - The client configuration for this client.

requestMetricCollector - optional request metric collector to be used at the http client level; can be null.

Method Detail

setEndpoint

@Deprecated
public void setEndpoint(String endpoint)
                             throws IllegalArgumentException

Deprecated. use AwsClientBuilder.setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));

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.

setEndpoint

@Deprecated
public void setEndpoint(String endpoint,
                                    String serviceName,
                                    String regionId)

Deprecated. Please use the client builders instead. The AwsClientBuilder.withEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) method on the builder allows setting both endpoint and signing region. See Creating Service Clients for more information.

Allows specifying the endpoint along with signing information (service name and signing region). This method will overwrite any information set previously by any set/with/configure Region/Endpoint methods.

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

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.

getSignerByURI

public Signer getSignerByURI(URI uri)

Returns the signer based on the given URI and the current AWS client configuration. Currently only the SQS client can have different region on a per request basis. For other AWS clients, the region remains the same on a per AWS client level.

Note, however, the signer returned for S3 is incomplete at this stage as the information on the S3 bucket and key is not yet known.

setRegion

@Deprecated
public void setRegion(Region region)
                           throws IllegalArgumentException

Deprecated. use AwsClientBuilder.setRegion(String)

An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

This method is not threadsafe. A region 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 or retrying.

By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.

Parameters:

region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region.

Throws:

IllegalArgumentException - If the given region is null, or if this service isn't available in the given region. See Region.isServiceSupported(String)

See Also:

Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)

configureRegion

@Deprecated
public final void configureRegion(Regions region)

Deprecated. use AwsClientBuilder.setRegion(String)

Convenient method for setting region.

Parameters:

region - region to set to; must not be null.

See Also:

setRegion(Region)

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

@Deprecated
public void addRequestHandler(RequestHandler requestHandler)

Deprecated. by addRequestHandler(RequestHandler2). 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.

addRequestHandler

@Deprecated
public void addRequestHandler(RequestHandler2 requestHandler2)

Deprecated. use AwsClientBuilder.withRequestHandlers(RequestHandler2...)

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

Parameters:

requestHandler2 - The new handler to add to the current list of request handlers.

removeRequestHandler

@Deprecated
public void removeRequestHandler(RequestHandler requestHandler)

Deprecated. use AwsClientBuilder.withRequestHandlers(RequestHandler2...)

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.

removeRequestHandler

@Deprecated
public void removeRequestHandler(RequestHandler2 requestHandler2)

Deprecated. use AwsClientBuilder.withRequestHandlers(RequestHandler2...)

setTimeOffset

public void setTimeOffset(int timeOffset)

Sets the optional value for time offset for this client. This value will be applied to all requests processed through this client. Value is in seconds, positive values imply the current clock is "fast", negative values imply clock is slow.

Parameters:

timeOffset - The optional value for time offset (in seconds) for this client.

withTimeOffset

public AmazonWebServiceClient withTimeOffset(int timeOffset)

Sets the optional value for time offset for this client. This value will be applied to all requests processed through this client. Value is in seconds, positive values imply the current clock is "fast", negative values imply clock is slow.

Parameters:

timeOffset - The optional value for time offset (in seconds) for this client.

Returns:

the updated web service client

getTimeOffset

public int getTimeOffset()

Returns the optional value for time offset for this client. This value will be applied to all requests processed through this client. Value is in seconds, positive values imply the current clock is "fast", negative values imply clock is slow.

Returns:

The optional value for time offset (in seconds) for this client.

getRequestMetricsCollector

public RequestMetricCollector getRequestMetricsCollector()

Returns the client specific RequestMetricCollector; or null if there is none.

getServiceName

public String getServiceName()

Returns the service abbreviation for this service, used for identifying service endpoints by region, identifying the necessary signer, etc. Used to be call "getServiceAbbreviation".

getEndpointPrefix

public String getEndpointPrefix()

Returns:

the service name that should be used when computing the region endpoints. This method returns the value of the regionMetadataServiceName configuration in the internal config file if such configuration is specified for the current client, otherwise it returns the same service name that is used for request signing.

setServiceNameIntern
