- Field Detail
  - ENDPOINT_PREFIX
```
static final String ENDPOINT_PREFIX
```
    The region metadata service name for computing region endpoints. You can use this value to retrieve metadata (such as supported regions) of the service.

  - 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.

  - addLayerVersionPermission
```
AddLayerVersionPermissionResult addLayerVersionPermission(AddLayerVersionPermissionRequest addLayerVersionPermissionRequest)
```
    Adds permissions to the resource-based policy of a version of an AWS Lambda layer. Use this action to grant layer usage permission to other accounts. You can grant permission to a single account, all AWS accounts, or all accounts in an organization.
    
    To revoke permission, call RemoveLayerVersionPermission with the statement ID that you specified when you added it.
    
    Parameters:
    
    addLayerVersionPermissionRequest -
    
    Returns:
    
    Result of the AddLayerVersionPermission 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.
    
    TooManyRequestsException - Request throughput limit exceeded.
    
    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 - The permissions policy for the resource is too large. Learn more
    
    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.

    AWS API Documentation
  - addPermission
```
AddPermissionResult addPermission(AddPermissionRequest addPermissionRequest)
```
    Grants an AWS service or another account permission to use a function. You can apply the policy at the function level, or specify a qualifier to restrict access to a single version or alias. If you use a qualifier, the invoker must use the full Amazon Resource Name (ARN) of that version or alias to invoke the function.
    
    To grant permission to another account, specify the account ID as the Principal. For AWS services, the principal is a domain-style identifier defined by the service, like s3.amazonaws.com or sns.amazonaws.com. For AWS services, you can also specify the ARN or owning account of the associated resource as the SourceArn or SourceAccount. If you grant permission to a service principal without specifying the source, other accounts could potentially configure resources in their account to invoke your Lambda function.
    
    This action adds a statement to a resource-based permission policy for the function. For more information about function policies, see Lambda Function Policies.
    
    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 - The permissions policy for the resource is too large. Learn more
    
    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 for a Lambda function version. Use aliases to provide clients with a function identifier that you can update to invoke a different version.
    
    You can also map an alias to split invocation requests between two versions. Use the RoutingConfig parameter to specify a second version and the percentage of invocation requests that it receives.
    
    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.

    See Also:
    
    AWS API Documentation
  - createEventSourceMapping
```
CreateEventSourceMappingResult createEventSourceMapping(CreateEventSourceMappingRequest createEventSourceMappingRequest)
```
    Creates a mapping between an event source and an AWS Lambda function. Lambda reads items from the event source and triggers the function.
    
    For details about each event source type, see the following topics.
    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.

    AWS API Documentation
  - createFunction
```
CreateFunctionResult createFunction(CreateFunctionRequest createFunctionRequest)
```
    Creates a Lambda function. To create a function, you need a deployment package and an execution role. The deployment package contains your function code. The execution role grants the function permission to use AWS services, such as Amazon CloudWatch Logs for log streaming and AWS X-Ray for request tracing.
    
    A function has an unpublished version, and can have published versions and aliases. The unpublished version changes when you update your function's code and configuration. A published version is a snapshot of your function code and configuration that can't be changed. An alias is a named resource that maps to a version, and can be changed to map to a different version. Use the Publish parameter to create version 1 of your function from its initial configuration.
    
    The other parameters let you configure version-specific and function-level settings. You can modify version-specific settings later with UpdateFunctionConfiguration. Function-level settings apply to both the unpublished and published versions of the function, and include tags (TagResource) and per-function concurrency limits (PutFunctionConcurrency).
    
    If another account or an AWS service invokes your function, use AddPermission to grant permission by creating a resource-based IAM policy. You can grant permissions at the function level, on a version, or on an alias.
    
    To invoke your function directly, use Invoke. To invoke your function in response to events in other AWS services, create an event source mapping (CreateEventSourceMapping), or configure a function trigger in the other service. For more information, see Invoking Functions.
    
    Parameters:
    
    createFunctionRequest -
    
    Returns:
    
    Result of the CreateFunction 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.
    
    ResourceNotFoundException - The resource (for example, a Lambda function or access policy statement) specified in the request does not exist.
    
    ResourceConflictException - The resource already exists.
    
    TooManyRequestsException - Request throughput limit exceeded.
    
    CodeStorageExceededException - You have exceeded your maximum total code size per account. Learn more

  - invoke
```
InvokeResult invoke(InvokeRequest invokeRequest)
```
    Invokes a Lambda function. You can invoke a function synchronously (and wait for the response), or asynchronously. To invoke a function asynchronously, set InvocationType to Event.
    
    For synchronous invocation, details about the function response, including errors, are included in the response body and headers. For either invocation type, you can find more information in the execution log and trace. To record function errors for asynchronous invocations, configure your function with a dead letter queue.
    
    When an error occurs, your function may be invoked multiple times. Retry behavior varies by error type, client, event source, and invocation type. For example, if you invoke a function asynchronously and it returns an error, Lambda executes the function up to two more times. For more information, see Retry Behavior.
    
    The status code in the API response doesn't reflect function errors. Error codes are reserved for errors that prevent your function from executing, such as permissions errors, limit errors, or issues with your function's code and configuration. For example, Lambda returns TooManyRequestsException if executing the function would cause you to exceed a concurrency limit at either the account level ( ConcurrentInvocationLimitExceeded) or function level ( ReservedFunctionConcurrentInvocationLimitExceeded).
    
    For functions with a long timeout, your client might be disconnected during synchronous invocation while it waits for a response. Configure your HTTP client, SDK, firewall, proxy, or operating system to allow for long connections with timeout or keep-alive settings.
    
    This operation requires permission for the lambda:InvokeFunction action.
    
    Parameters:
    
    invokeRequest -
    
    Returns:
    
    Result of the Invoke operation returned by the service.

  - putFunctionConcurrency
```
PutFunctionConcurrencyResult putFunctionConcurrency(PutFunctionConcurrencyRequest putFunctionConcurrencyRequest)
```
    Sets the maximum number of simultaneous executions for a function, and reserves capacity for that concurrency level.
    
    Concurrency settings apply to the function as a whole, including all published versions and the unpublished version. Reserving concurrency both ensures that your function has capacity to process the specified number of events simultaneously, and prevents it from scaling beyond that level. Use GetFunction to see the current setting for a function.
    
    Use GetAccountSettings to see your regional concurrency limit. You can reserve concurrency for as many functions as you like, as long as you leave at least 100 simultaneous executions unreserved for functions that aren't configured with a per-function limit. For more information, see Managing Concurrency.

    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.
    
    CodeStorageExceededException - You have exceeded your maximum total code size per account. Learn more
    
    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.

  - updateFunctionConfiguration
```
UpdateFunctionConfigurationResult updateFunctionConfiguration(UpdateFunctionConfigurationRequest updateFunctionConfigurationRequest)
```
    Modify the version-specific settings of a Lambda function.
    
    These settings can vary between versions of a function and are locked when you publish a version. You can't modify the configuration of a published version, only the unpublished version.
    
    To configure function concurrency, use PutFunctionConcurrency. To grant invoke permissions to an account or AWS service, use AddPermission.
    
    Parameters:
    
    updateFunctionConfigurationRequest -
    
    Returns:
    
    Result of the UpdateFunctionConfiguration 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.
    
    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.

  - 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.
