abstract type TermTree >: Null <: Universe.TermTreeApi with Universe.Tree

A tree for a term. Not all trees representing terms are TermTrees; use isTerm to reliably identify terms.

  21. abstract def symbol: Universe.Symbol

    Symbol of the tree.

    Symbol of the tree.

    For most trees symbol is null. In SymTrees, it is overridden and implemented with a var, initialized to NoSymbol.

    Trees which are not SymTrees but which carry symbols do so by overriding def symbol to forward it elsewhere. Examples:

    • Super(qual, _) has qual's symbol,
    • Apply(fun, args) has fun's symbol,
    • TypeApply(fun, args) has fun's symbol,
    • AppliedTypeTree(tpt, args) has tpt's symbol,
    • TypeTree(tpe) has tpe's typeSymbol, if tpe != null.

    TreeApi
  22. abstract def tpe: Universe.Type

    Type of the tree.

    Type of the tree.

    Upon creation most trees have their tpe set to null. Types are typically assigned to trees during typechecking. Some node factory methods set tpe immediately after creation.

    When the typechecker encounters a tree with a non-null tpe, it will assume it to be correct and not check it again. This means one has to be careful not to erase the tpe field of subtrees.
