包路径：org.geotools.data.Query
类名称：Query
方法名：setStartIndex

Query.setStartIndex介绍

[英]Set the index of the first feature to retrieve. This can be used in conjuction with #setMaxFeatures(int) to 'page' through a feature data source.
[中]设置要检索的第一个要素的索引。这可以与#setMaxFeatures（int）结合使用，通过功能数据源“分页”。

query.getMaxFeatures() == Integer.MAX_VALUE ? null : query.getMaxFeatures();
  query.setStartIndex(null);
  query.setMaxFeatures(Query.DEFAULT_MAX);
} else {
      query.getMaxFeatures() == Integer.MAX_VALUE ? null : query.getMaxFeatures();
  query.setStartIndex(null);
  query.setMaxFeatures(Query.DEFAULT_MAX);
