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:createWriter
[英]Returns an index writer to perform batched write operations for the given data type name. It assumes the type has already been used previously or added using addType and assumes one or more indices have been provided for this type.
[中]返回索引编写器,以对给定的数据类型名称执行批处理写入操作。它假定以前已经使用过该类型或使用addType添加过该类型,并假定已为此类型提供了一个或多个索引。
