本文整理了Java中org.locationtech.geowave.core.store.api.DataStore.query()方法的一些代码示例,展示了DataStore.query()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。DataStore.query()方法的具体详情如下:
包路径:org.locationtech.geowave.core.store.api.DataStore
类名称:DataStore
方法名:query

DataStore.query介绍

[英]Returns all data in this data store that matches the query parameter. All data that matches the query will be returned as an instance of the native data type. The Iterator must be closed when it is no longer needed - this wraps the underlying scanner implementation and closes underlying resources.
[中]返回此数据存储中与查询参数匹配的所有数据。与查询匹配的所有数据都将作为本机数据类型的实例返回。当不再需要迭代器时,必须关闭迭代器-这将包装底层扫描程序实现并关闭底层资源。
