我在java中使用aws cdk
给定以下使用内在函数的yaml输入！裁判

Parameters:

    EnvironmentName:
        Description: An environment name that will be prefixed to resource names
        Type: String

    VpcCIDR: 
        Description: Please enter the IP range (CIDR notation) for this VPC
        Type: String
        Default: 10.0.0.0/16
Resources:

    VPC: 
        Type: AWS::EC2::VPC
        Properties:
            CidrBlock: !Ref VpcCIDR
            EnableDnsHostnames: true
            Tags: 
                - Key: Name 
                  Value: !Ref EnvironmentName

使用以下aws cdk代码，c.getcidrblock（）返回${token[vpccidr.ref.79]}
如何获得值10.0.0.0/16？

public HelloCdkStack(final Construct scope, final String id, final StackProps props) throws IOException {
    super(scope, id, props);

    CfnInclude template = CfnInclude.Builder.create(this, "Template")
            .templateFile("/home/vmdovs/NetBeansProjects/cf-import/contentTests/KirillosExamples/yaml2/ExampleFullWithSelectTest.yml")
            .build();

    List<IConstruct> lic = template.getNode().getChildren();
    Iterator<IConstruct> itIC = lic.iterator();

    while (itIC.hasNext()) {

        IConstruct IC = itIC.next();

        if (IC instanceof CfnVPC) {
            System.out.println("IC is instanceof of CfnVPC");
            CfnVPC C = (CfnVPC)IC;
            System.out.println("cidr: " + C.getCidrBlock());

        }
    }
}
