def allPaths[A](tree: Tree[A]): List[List[A]]

Attributes

Returns

all the paths from root to leaves

Inherited from:
Trees
def bottomUp[A, B](t: Tree[A], f: (A, LazyList[B]) => B): Tree[B]

map a Tree from leaves to root by replacing each node with the result of a function taking that node and the mapping of all its children.

map a Tree from leaves to root by replacing each node with the result of a function taking that node and the mapping of all its children.

This is used in JUnit to map a Tree[Description] where no Description objects are related to a Tree[Description] where each node returns the children nodes on the "getChildren" method
