- Field Detail
  - ENDPOINT_PREFIX
```
static final String ENDPOINT_PREFIX

  - setEndpoint
```
@Deprecated
void setEndpoint(String endpoint)
```
    Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
    
    Overrides the default endpoint for this client ("lambda.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.
    Callers can pass in just the endpoint (ex: "lambda.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "lambda.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: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
    This method is not threadsafe. An endpoint 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.
    
    Parameters:
    
    endpoint - The endpoint (ex: "lambda.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "lambda.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
  - setRegion
```
@Deprecated
void setRegion(Region region)
```
    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.
    By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.
    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.
    
    Parameters:
    
    region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.
    
    See Also:
    
    Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration), Region.isServiceSupported(String)
  - addPermission
```
AddPermissionResult addPermission(AddPermissionRequest addPermissionRequest)
```
    Adds a permission to the resource policy associated with the specified AWS Lambda function. You use resource policies to grant permissions to event sources that use the push model. In a push model, event sources (such as Amazon S3 and custom applications) invoke your Lambda function. Each permission you add to the resource policy allows an event source permission to invoke the Lambda function.
    
    Permissions apply to the Amazon Resource Name (ARN) used to invoke the function, which can be unqualified (the unpublished version of the function), or include a version or alias. If a client uses a version or alias to invoke a function, use the Qualifier parameter to apply permissions to that ARN. For more information about versioning, see AWS Lambda Function Versioning and Aliases.
    
    This operation requires permission for the lambda:AddPermission action.
    
    Parameters:
    
    addPermissionRequest -
    
    Returns:
    
    Result of the AddPermission operation returned by the service.
    
    Throws:
    
    ServiceException - The AWS Lambda service encountered an internal error.
    
    ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
    
    ResourceConflictException - The resource already exists.
    
    InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.
    
    PolicyLengthExceededException - Lambda function access policy is limited to 20 KB.
    
    TooManyRequestsException - Request throughput limit exceeded
    
    PreconditionFailedException - The RevisionId provided does not match the latest RevisionId for the Lambda function or alias. Call the GetFunction or the GetAlias API to retrieve the latest RevisionId for your resource.

  - createAlias
```
CreateAliasResult createAlias(CreateAliasRequest createAliasRequest)
```
    Creates an alias that points to the specified Lambda function version. For more information, see Introduction to AWS Lambda Aliases.
    
    Alias names are unique for a given function. This requires permission for the lambda:CreateAlias action.
    
    Parameters:
    
    createAliasRequest -
    
    Returns:
    
    Result of the CreateAlias operation returned by the service.
    
    Throws:
    
    ServiceException - The AWS Lambda service encountered an internal error.
    
    ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
    
    ResourceConflictException - The resource already exists.
    
    InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.
    
    TooManyRequestsException - Request throughput limit exceeded

    AWS API Documentation
  - createEventSourceMapping
```
CreateEventSourceMappingResult createEventSourceMapping(CreateEventSourceMappingRequest createEventSourceMappingRequest)
```
    Identifies a poll-based event source for a Lambda function. It can be either an Amazon Kinesis or DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the event source.
    
    This association between a poll-based source and a Lambda function is called the event source mapping.
    
    You provide mapping information (for example, which stream or SQS queue to read from and which Lambda function to invoke) in the request body.
    
    Amazon Kinesis or DynamoDB stream event sources can be associated with multiple AWS Lambda functions and a given Lambda function can be associated with multiple AWS event sources. For Amazon SQS, you can configure multiple queues as event sources for a single Lambda function, but an SQS queue can be mapped only to a single Lambda function.
    
    You can configure an SQS queue in an account separate from your Lambda function's account. Also the queue needs to reside in the same AWS region as your function.
    
    If you are using versioning, you can specify a specific function version or an alias via the function name parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases.
    
    This operation requires permission for the lambda:CreateEventSourceMapping action.
    
    Parameters:
    
    createEventSourceMappingRequest -
    
    Returns:
    
    Result of the CreateEventSourceMapping operation returned by the service.
    
    Throws:
    
    ServiceException - The AWS Lambda service encountered an internal error.
    
    InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.
    
    ResourceConflictException - The resource already exists.
    
    TooManyRequestsException - Request throughput limit exceeded
    
    ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.

When you remove permissions, disable the event source mapping or trigger configuration first to avoid errors.
    
    Permissions apply to the Amazon Resource Name (ARN) used to invoke the function, which can be unqualified (the unpublished version of the function), or include a version or alias. If a client uses a version or alias to invoke a function, use the Qualifier parameter to apply permissions to that ARN. For more information about versioning, see AWS Lambda Function Versioning and Aliases.
    
    You need permission for the lambda:RemovePermission action.
    
    Parameters:

  - updateEventSourceMapping
```
UpdateEventSourceMappingResult updateEventSourceMapping(UpdateEventSourceMappingRequest updateEventSourceMappingRequest)
```
    You can update an event source mapping. This is useful if you want to change the parameters of the existing mapping without losing your position in the stream. You can change which function will receive the stream records, but to change the stream itself, you must create a new mapping.
    
    If you disable the event source mapping, AWS Lambda stops polling. If you enable again, it will resume polling from the time it had stopped polling, so you don't lose processing of any records. However, if you delete event source mapping and create it again, it will reset.
    
    This operation requires permission for the lambda:UpdateEventSourceMapping action.
    
    Parameters:
    
    updateEventSourceMappingRequest -
    
    Returns:
    
    Result of the UpdateEventSourceMapping operation returned by the service.
    
    Throws:
    
    ServiceException - The AWS Lambda service encountered an internal error.
    
    ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
    
    InvalidParameterValueException - One of the parameters in the request is invalid. For example, if you provided an IAM role for AWS Lambda to assume in the CreateFunction or the UpdateFunctionConfiguration API, that AWS Lambda is unable to assume you will get this exception.
    
    TooManyRequestsException - Request throughput limit exceeded
    
    ResourceConflictException - The resource already exists.
    
    ResourceInUseException - The operation conflicts with the resource's availability. For example, you attempted to update an EventSoure Mapping in CREATING, or tried to delete a EventSoure mapping currently in the UPDATING state.

  - shutdown
```
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.
  - getCachedResponseMetadata
```
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 a request.
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
