@Generated(value="jsii-pacmak/1.97.0 (build 729de35)", date="2024-04-24T21:00:24.306Z") @Stability(Stable) public class App extends Stage
A construct which represents an entire CDK app. This construct is normally the root of the construct tree.

You would normally define an App instance in your program's entrypoint, then define constructs where the app is used as the parent scope.

After all the child constructs are defined within the app, you should call app.synth() which will emit a "cloud assembly" from this app into the directory specified by outdir. Cloud assemblies includes artifacts such as CloudFormation templates and assets that are needed to deploy this app into the AWS cloud.

Example: 

 import software.amazon.awscdk.*;
 import software.amazon.awscdk.services.s3.*;
 IBucket bucket;
 App app = new App();
 Stack stack = new Stack(app, "Stack");
 Table.Builder.create(stack, "Table")
         .partitionKey(Attribute.builder()
                 .name("id")
                 .type(AttributeType.STRING)
                 .build())
         .importSource(ImportSourceSpecification.builder()
                 .compressionType(InputCompressionType.GZIP)
                 .inputFormat(InputFormat.csv(CsvOptions.builder()
                         .delimiter(",")
                         .headerList(List.of("id", "name"))
                         .build()))
                 .bucket(bucket)
                 .keyPrefix("prefix")
                 .build())
         .build();
