@Generated(value="jsii-pacmak/1.94.0 (build b380f01)", date="2024-02-23T02:06:34.448Z") @Stability(Stable) public class CfnEventSourceMapping extends CfnResource implements IInspectable
The AWS::Lambda::EventSourceMapping resource 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. In particular, each of the topics describes the required and optional parameters for the specific event source.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.lambda.*;
 CfnEventSourceMapping cfnEventSourceMapping = CfnEventSourceMapping.Builder.create(this, "MyCfnEventSourceMapping")
