public class Version
extends QualifiedFunctionBase
implements IVersion

Tag the current state of a Function with a Version number.

Avoid using this resource directly. If you need a Version object, use function.currentVersion instead. That will add a Version object to your template, and make sure the Version is invalidated whenever the Function object changes. If you use the Version resource directly, you are responsible for making sure it is invalidated (by changing its logical ID) whenever necessary.

Version resources can then be used in Alias resources to refer to a particular deployment of a Lambda.

If you want to ensure that you're associating the right version with the right deployment, specify the codeSha256 property while creating the `Version.

Example:

 CfnParametersCode lambdaCode = Code.fromCfnParameters();
 Function func = Function.Builder.create(this, "Lambda")
         .code(lambdaCode)
         .handler("index.handler")
         .runtime(Runtime.NODEJS_14_X)
         .build();
 // used to make sure each CDK synthesis produces a different Version
 Version version = func.getCurrentVersion();
 Alias alias = Alias.Builder.create(this, "LambdaAlias")
         .aliasName("Prod")
         .version(version)
         .build();
 LambdaDeploymentGroup.Builder.create(this, "DeploymentGroup")
         .alias(alias)
         .deploymentConfig(LambdaDeploymentConfig.LINEAR_10PERCENT_EVERY_1MINUTE)
         .build();
