接口 IFeatureCollection
-
- 所有已知实现类:
- DatasetFeatureCollection, DatasetGridFeatureCollection, I3SFeatureCollction, ModelFeatureCollection, OSGBFeatureCollection, PointCloudFeatureCollection, S3MFeatureCollection, ThreeDTilesFeatureCollection
public interface IFeatureCollection extends Iterable<IFeature>
FeatureCollection 表示同一类型要素的集合。
IFeatureCollection 其中 Feature 的属性信息应该是一致的,为了方便描述要素或要素集的结构,新增加类型 Schema-要素集结构描述,需要和内部要素的结构一致- 作者:
