我怎样才能在java中获得bigquery表模式

假设我有这个myTableBQ 中的表：

[
  {"name": "executionId", "type": "STRING"},
  {"name":"metadata", "type":"record","fields":[
    {"name":"fileName", "type":"STRING"},
    {"name":"fileType", "type":"STRING"},
    {"name":"errors", "type":"STRING"}
  ]}
]

现在我正在尝试在我的代码中获取表架构。 这是我尝试使用这个的example https://github.com/GoogleCloudPlatform/google-cloud-java/blob/master/google-cloud-examples/src/main/java/com/google/cloud/examples/bigquery/snippets/BigQuerySnippets.java:

import com.google.cloud.examples.bigquery.snippets.*;

public class MyClass {
    public static void main(String[] args) throws Exception {
        BigQuery bigquery = BigQueryOptions.getDefaultInstance().getService();
        BigQuerySnippets bigQuerySnippets = new BigQuerySnippets(bigquery);
        Table table = bigQuerySnippets.getTable("MY_DATASET", "myTable");

现在我该如何继续？ 做table有这个方法吗？

Table http://googlecloudplatform.github.io/google-cloud-java/0.8.0/apidocs/com/google/cloud/bigquery/Table.html延伸表信息 http://googlecloudplatform.github.io/google-cloud-java/0.8.0/apidocs/com/google/cloud/bigquery/TableInfo.html，这样你就可以得到表定义 http://googlecloudplatform.github.io/google-cloud-java/0.8.0/apidocs/?com/google/cloud/bigquery/package-summary.html来自 TableInfo 和Schema http://googlecloudplatform.github.io/google-cloud-java/0.8.0/apidocs/com/google/cloud/bigquery/Schema.html从表定义：

Schema schema = table.getDefinition().getSchema();
