Type Members

  1. implicit class CleanedTree[A] extends AnyRef

    This implicit can be used to remove None nodes in a Tree

  2. implicit class TreeLocx[T] extends AnyRef

    Implicit definition to add more functionalities to the TreeLoc class

  3. implicit class Treex[A] extends AnyRef

    Implicit definition to add more functionalities to the Tree trait

  5. def bottomUp[A, B](t: Tree[A], f: (A, Stream[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

  6. def clean[A](t: Tree[Option[A]])(implicit initial: A): Tree[A]

    remove None nodes from a tree

  20. def prune[A](t: Tree[A], f: (Tree[A]) ⇒ Option[A])(implicit initial: A): Tree[A]

    remove nodes from a tree if they are None according to a function f

  21. def prune[A, B](t: Tree[A], f: (A) ⇒ Option[B]): Option[Tree[B]]

    remove nodes from a tree if they are None according to a function f

  22. def size[A](t: TreeLoc[A]): Int
