@Generated(value="jsii-pacmak/1.118.0 (build 02eec31)", date="2025-11-10T13:40:08.774Z") @Stability(Stable) public class CfnVersion extends CfnResource implements IInspectable, IVersionRef
The AWS::Lambda::Version resource creates a version from the current code and configuration of a function. Use versions to create a snapshot of your function code and configuration that doesn't change.

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.*;
 CfnVersion cfnVersion = CfnVersion.Builder.create(this, "MyCfnVersion")
         .functionName("functionName")
         // the properties below are optional
         .codeSha256("codeSha256")
         .description("description")
         .provisionedConcurrencyConfig(ProvisionedConcurrencyConfigurationProperty.builder()
                 .provisionedConcurrentExecutions(123)
                 .build())
         .runtimePolicy(RuntimePolicyProperty.builder()
                 .updateRuntimeOn("updateRuntimeOn")
                 // the properties below are optional
                 .runtimeVersionArn("runtimeVersionArn")
                 .build())
         .build();
