如何在Beam2.0中获取复合PTransform中的PipelineOptions？

import org.apache.beam.sdk.options.PipelineOptions;
import org.apache.beam.sdk.options.PipelineOptionsFactory;
import org.apache.beam.sdk.transforms.DoFn;
import org.apache.beam.sdk.transforms.PTransform;
import org.apache.beam.sdk.values.PCollection;

public class MyCompositeTransform extends PTransform<PCollection<String>, PCollection<String>> {

  public static class MyOptions extends PipelineOptions {
    // 定义复合PTransform所需的选项
    // ...
  }

  public static MyOptions getOptions(PipelineOptions options) {
    // 根据传入的PipelineOptions对象创建新的选项对象
    MyOptions myOptions = PipelineOptionsFactory.as(MyOptions.class);
    // 设置复合PTransform所需的选项
    // ...
    return myOptions;
  }

  @Setup
  public void setup() {
    // 在这里获取PipelineOptions并设置复合PTransform所需的选项
    MyOptions myOptions = getOptions(getPipeline().getOptions());
    // ...
  }

  @Override
  public PCollection<String> expand(PCollection<String> input) {
    // 在这里可以通过getPipeline().getOptions()获取PipelineOptions对象
    MyOptions myOptions = getPipeline().getOptions().as(MyOptions.class);
    // 使用PipelineOptions对象执行复合PTransform的逻辑
    // ...
    return output;
  }
}
