@Generated(value="jsii-pacmak/1.119.0 (build 1634eac)", date="2025-11-20T23:37:22.706Z") @Stability(Stable) public class CfnFunctionDefinition extends CfnResource implements IInspectable, IFunctionDefinitionRef, ITaggable
The AWS::Greengrass::FunctionDefinition resource represents a function definition for AWS IoT Greengrass .

Function definitions are used to organize your function definition versions.

Function definitions can reference multiple function definition versions. All function definition versions must be associated with a function definition. Each function definition version can contain one or more functions.

When you create a function definition, you can optionally include an initial function definition version. To associate a function definition version later, create an AWS::Greengrass::FunctionDefinitionVersion resource and specify the ID of this function definition.

After you create the function definition version that contains the functions you want to deploy, you must add it to your group version. For more information, see AWS::Greengrass::Group .

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
