- Constructor Detail
  - AmazonWebServiceClient
```
public AmazonWebServiceClient(LegacyClientConfiguration clientConfiguration)
```
    Constructs a new AmazonWebServiceClient object using the specified configuration.
    
    Parameters:
    
    clientConfiguration - The client configuration for this client.
  - AmazonWebServiceClient
```
public AmazonWebServiceClient(LegacyClientConfiguration 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.

  - 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 LegacyClientConfiguration 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.
  - 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(Region)
    
    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 LegacyClientConfiguration supplied at construction.
    
    Parameters:
    
    region - The of this client will communicate with. See Region.of(String) for accessing a given of.
    
    Throws:
    
    IllegalArgumentException - If the given of is null, or if this service isn't available in the given of. See Region#getRegionMetadata() isServiceSupported(String)}

  - 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.
  - 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.
  - 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.
  - 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 is the values 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.
    
    Returns:
    
    the service name
  - setServiceNameIntern
```
public final void setServiceNameIntern(String serviceName)
```
    An internal method used to explicitly override the service name computed by the default implementation. This method is not expected to be normally called except for AWS internal development purposes.
  - getSignerRegionOverride
```
public final String getSignerRegionOverride()
```
    Returns the signer region override.
  - setSignerRegionOverride
```
public final void setSignerRegionOverride(String signerRegionOverride)
```
    An internal method used to explicitly override the internal signer region computed by the default implementation. This method is not expected to be normally called except for AWS internal development purposes.
  - withRegion
```
@Deprecated
public <T extends AmazonWebServiceClient> T withRegion(Region region)
```
    Deprecated. use AwsClientBuilder.withRegion(Region) for example: AmazonSNSClient.builder().withRegion(region).build();
    
    Fluent method for setRegion(Region).
    Example: AmazonDynamoDBClient client = new AmazonDynamoDBClient(...).<AmazonDynamoDBClient>withRegion(...);

    setRegion(Region)
  - withEndpoint
```
@Deprecated
public <T extends AmazonWebServiceClient> T withEndpoint(String endpoint)
```
    Deprecated. use AwsClientBuilder.withEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: AmazonSNSClient.builder() .withEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion)).build();
    
    Fluent method for setEndpoint(String).
    Example: AmazonDynamoDBClient client = new AmazonDynamoDBClient(...).<AmazonDynamoDBClient>withEndPoint(...);
    
    See Also:
    
    setEndpoint(String)
  - makeImmutable
```
@Deprecated
public final void makeImmutable()

    Deprecated.
    
    Internal only API to lock a client's mutable methods. Only intended for use by the fluent builders.
