Value Members

  1. final def :@(newType: Type): Self

    Return this Node with a Type assigned (if no other type has been seen for it yet) or a typed copy.

    Return this Node with a Type assigned (if no other type has been seen for it yet) or a typed copy.

  2. def childNames: Vector[String]

    Names for the child nodes to show in AST dumps.

    Names for the child nodes to show in AST dumps. Defaults to a numbered sequence starting at 0 but can be overridden by subclasses to produce more suitable names.

    OptionFold → Node
  3. lazy val children: ConstArray[Node]

    All child nodes of this node.

    All child nodes of this node. Must be implemented by subclasses.

  4. def childrenForeach[R](f: (Node) => R): Unit

    Apply a side-effecting function to all direct children from left to right.

    Apply a side-effecting function to all direct children from left to right. Note that

    n.childrenForeach(f)

    is equivalent to 

    n.children.foreach(f)

    but can be implemented more efficiently in Node subclasses.

  9. def hasType: Boolean

    Check if this node has a type without marking the type as seen.

  10. val ifEmpty: Node
  11. final def infer(scope: Scope = Map.empty, typeChildren: Boolean = false): Self

    Rebuild this node and all children with their computed type.

    Rebuild this node and all children with their computed type. If this node already has a type, the children are only type-checked again if typeChildren is true. if retype is also true, the existing type of this node is replaced. If this node does not yet have a type, the types of all children are computed first.

  12. val map: Node
  13. def mapChildren(f: (Node) => Node, keepType: Boolean = false): Self

    Apply a mapping function to all children of this node and recreate the node with the new children.

    Apply a mapping function to all children of this node and recreate the node with the new children. If all new children are identical to the old ones, this node is returned. If keepType is true, the type of this node is kept even when the children have changed.
