Method Detail

builder

public static AWSLambdaClientBuilder builder()

addPermission

public AddPermissionResult addPermission(AddPermissionRequest request)

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 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.

For information about the push model, see AWS Lambda: How it Works.

If you are using versioning, the permissions you add are specific to the Lambda function version or alias you specify in the AddPermission request via the Qualifier parameter. For more information about versioning, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:AddPermission action.

Specified by:

addPermission in interface AWSLambda

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

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.

createEventSourceMapping

public CreateEventSourceMappingResult createEventSourceMapping(CreateEventSourceMappingRequest request)

Identifies a stream as an event source for a Lambda function. It can be either an Amazon Kinesis stream or an Amazon DynamoDB stream. AWS Lambda invokes the specified function when records are posted to the stream.

This association between a stream source and a Lambda function is called the event source mapping.

This event source mapping is relevant only in the AWS Lambda pull model, where AWS Lambda invokes the function. For more information, see AWS Lambda: How it Works in the AWS Lambda Developer Guide.

You provide mapping information (for example, which stream to read from and which Lambda function to invoke) in the request body.

Each event source, such as an Amazon Kinesis or a DynamoDB stream, can be associated with multiple AWS Lambda function. A given Lambda function can be associated with multiple AWS event sources.

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.

Returns a list of event source mappings you created using the CreateEventSourceMapping (see CreateEventSourceMapping).

For each mapping, the API returns configuration information. You can optionally specify filters to retrieve specific event source mappings.

If you are using the versioning feature, you can get list of event source mappings for a specific Lambda function version or an alias as described in the FunctionName parameter. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

This operation requires permission for the lambda:ListEventSourceMappings action.

Specified by:

listEventSourceMappings in interface AWSLambda

Parameters:

listEventSourceMappingsRequest -

Returns:

Result of the ListEventSourceMappings 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.

updateEventSourceMapping

public UpdateEventSourceMappingResult updateEventSourceMapping(UpdateEventSourceMappingRequest request)

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 are using the versioning feature, you can update the event source mapping to map to a specific Lambda function version or alias as described in the FunctionName parameter. For information about the versioning feature, see AWS Lambda Function Versioning and Aliases.

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.

Specified by:

updateEventSourceMapping in interface AWSLambda

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.

getCachedResponseMetadata

public 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 the request.

Specified by:

getCachedResponseMetadata in interface AWSLambda

Parameters:

request - The originally executed request

Returns:

The response metadata for the specified request, or null if none is available.
