Deletes the specified Lambda function code and configuration.

When you delete a function the associated access policy is also deleted. You will need to delete the event source mappings explicitly.

This operation requires permission for the lambda:DeleteFunction action.

Parameters:
deleteFunctionRequest Container for the necessary parameters to execute the DeleteFunction service method on AWSLambda.
Throws:
com.amazonaws.services.lambda.model.ServiceException
com.amazonaws.services.lambda.model.ResourceNotFoundException
com.amazonaws.services.lambda.model.TooManyRequestsException
com.amazonaws.AmazonClientException If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
com.amazonaws.AmazonServiceException If an error response is returned by AWSLambda indicating either a problem with the data in the request, or a server side issue.

Adds a permission to the access policy associated with the specified AWS Lambda function. In a "push event" model, the access policy attached to the Lambda function grants Amazon S3 or a user application permission for the Lambda lambda:Invoke action. For information about the push model, see AWS Lambda: How it Works . Each Lambda function has one access policy associated with it. You can use the AddPermission API to add a permission to the policy. You have one access policy but it can have multiple permission statements.

This operation requires permission for the lambda:AddPermission action.

Parameters:
addPermissionRequest Container for the necessary parameters to execute the AddPermission service method on AWSLambda.
Returns:
The response from the AddPermission service method, as returned by AWSLambda.

You can remove individual permissions from an access policy associated with a Lambda function by providing a Statement ID.

Note that removal of a permission will cause an active event source to lose permission to the function.

You need permission for the lambda:RemovePermission action.

This operation requires permission for the lambda:CreateFunction action.

Parameters:
createFunctionRequest Container for the necessary parameters to execute the CreateFunction service method on AWSLambda.
Returns:

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 is the pull model, where AWS Lambda invokes the function. For more information, go to AWS Lambda: How it Works in the AWS Lambda Developer Guide .

This association between an Amazon Kinesis stream and a Lambda function is called the event source mapping. You provide the configuration information (for example, which stream to read from and which Lambda function to invoke) for the event source mapping 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.

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.

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