com.supermap.dtf.feature
类 DatasetGridFeatureCollection
- java.lang.Object
-
- com.supermap.dtf.feature.DatasetFeatureCollection
-
- com.supermap.dtf.feature.DatasetGridFeatureCollection
-
- 所有已实现的接口:
- IFeatureCollection, IProjectionTransformation, Iterable<IFeature>
public class DatasetGridFeatureCollection extends DatasetFeatureCollection
栅格数据集FC,栅格数据集本身不存储字段，所以额外声明个类用来存储一部分字段信息，重写迭代器的逻辑
只有一个 feature
