public class Duration
extends software.amazon.jsii.JsiiObject

Represents a length of time.

The amount can be specified either as a literal value (e.g: 10) which cannot be negative, or as an unresolved number token.

When the amount is passed as a token, unit conversion is not possible.

Example:

 import software.amazon.awscdk.services.lambda.*;
 Function fn = Function.Builder.create(this, "MyFunc")
         .runtime(Runtime.NODEJS_12_X)
         .handler("index.handler")
         .code(Code.fromInline("exports.handler = handler.toString()"))
         .build();
 Rule rule = Rule.Builder.create(this, "rule")
         .eventPattern(EventPattern.builder()
                 .source(List.of("aws.ec2"))
                 .build())
         .build();
 Queue queue = new Queue(this, "Queue");
 rule.addTarget(LambdaFunction.Builder.create(fn)
         .deadLetterQueue(queue) // Optional: add a dead letter queue
         .maxEventAge(Duration.hours(2)) // Optional: set the maxEventAge retry policy
         .retryAttempts(2)
         .build());
