java到scala转换 - r-tree的通用类型丢失？

Question

我想用https://github.com/davidmoten/rtree创建

RTree<String, Point> tree = RTree.create(); 
tree = tree.add("someStuff", Geometries.point(10,20)); 

斯卡拉我试图

val tree = RTree.create // note no generics here. Unsure how to add them 
tree.add("someStuff", Geometries.point(10,20)) 

这导致 cannot resolve symbol 'add' when trying to compile the Scala code。

Answer 1

这应该修复它：

val tree: RTree[String, Point] = RTree.create[String, Point]() 
tree.add("someStuff", Geometries.point(10,20))
