Type Members
- type Expr[+T] = Universe.Expr[T]
Expr wraps an abstract syntax tree and tags it with its type.
- type Modifiers = Universe.Modifiers
The type of tree modifiers.
- type Name = Universe.Name
The abstract type of names.
- type Position = Universe.Position
Defines a universe-specific notion of positions.
- type Scope = Universe.Scope
The base type of all scopes.
- type Symbol = Universe.Symbol
The type of symbols representing declarations.
- type TermName = Universe.TermName
The abstract type of names representing terms.
- type Tree = Universe.Tree
The type of Scala abstract syntax trees.
- type Type = Universe.Type
The type of Scala types, and also Scala type signatures.

Abstract Value Members
- abstract def Expr[T](tree: blackbox.Context.Tree)(implicit arg0: blackbox.Context.WeakTypeTag[T]): blackbox.Context.Expr[T]
A shorthand to create an expr.
A shorthand to create an expr.
Unlike the conventional expr factory, which requires a scala.reflect.api.TreeCreator, this one accepts a regular tree, but the resulting exprs are unable of being migrated to other universes/mirrors (the functionality normally not needed for macros, since there is only one compile-time universe and only one compile-time mirror).
- abstract def TypeTag[T](tpe: blackbox.Context.Type): blackbox.Context.TypeTag[T]
A shorthand to create a type tag.
A shorthand to create a type tag.
