# Universe

#### abstract class Universe extends api.Universe

The refinement of scala.reflect.api.Universe for the use by macro writers.

This universe provides mutability for reflection artifacts (e.g. macros can change types of compiler trees, add annotation to symbols representing definitions, etc) and exposes some internal compiler functionality such as `Symbol.deSkolemize` or `Tree.attachments`.

     where `tpe1` is the result of extrapolating `tpe` with regard to `tparams`. Extrapolating means that type variables in `tparams` occurring in covariant positions are replaced by upper bounds, (minus any SingletonClass markers), type variables in `tparams` occurring in contravariant positions are replaced by upper bounds, provided the resulting type is legal with regard to stability, and does not contain any type variable in `tparams`.

21. #### final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

    Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

    The `eq` method implements an equivalence relation on non-null instances of `AnyRef`, and has three additional properties:

    - It is consistent: for any non-null instances `x` and `y` of type `AnyRef`, multiple invocations of `x.eq(y)` consistently returns `true` or consistently returns `false`.
    - For any non-null instance `x` of type `AnyRef`, `x.eq(null)` and `null.eq(x)` returns `false`.
    - `null.eq(null)` returns `true`.

    When overriding the `equals` or `hashCode` methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (`o1 eq o2`), they should be equal to each other (`o1 == o2`) and they should hash to the same value (`o1.hashCode == o2.hashCode`).

    returns

      `true` if the argument is a reference to the receiver object; `false` otherwise.

    Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression `1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

30. #### def manifestToTypeTag[T](mirror: Any, manifest: Manifest[T]): api.Universe.TypeTag[T]

    Convert a scala.reflect.Manifest to a scala.reflect.api.TypeTags#TypeTag.

    Convert a scala.reflect.Manifest to a scala.reflect.api.TypeTags#TypeTag.

    Compiler usually generates these conversions automatically, when a manifest for a type `T` is in scope, and an implicit of type `TypeTag[T]` is requested, but this method can also be called manually. For example:

        manifestToTypeTag(scala.reflect.runtime.currentMirror, implicitly[Manifest[String]])

34. #### def reify[T](expr: T): Expr[T]

    Use `refiy` to produce the abstract syntax tree representing a given Scala expression.

    Use `refiy` to produce the abstract syntax tree representing a given Scala expression.

    For example:

        val five = reify{ 5 }    // Literal(Constant(5))
        reify{ 2 + 4 }           // Apply( Select( Literal(Constant(2)), newTermName("$plus")), List( Literal(Constant(4)) ) )
        reify{ five.splice + 4 } // Apply( Select( Literal(Constant(5)), newTermName("$plus")), List( Literal(Constant(4)) ) )

    The produced tree is path dependent on the Universe `reify` was called from.

    Use scala.reflect.api.Exprs#Expr.splice to embed an existing expression into a `reify` call. Use Expr to turn a Tree into an expression that can be spliced.

### API

The methods available for each reflection entity, without the implementation. Since the reflection entities are later overridden by runtime reflection and macros, their API counterparts guarantee a minimum set of methods that are implemented.

### Extractors

Extractors provide the machinery necessary to allow pattern matching and construction of reflection entities that is similar to case classes, although the entities are only abstract types that are later overridden.

### Tags

Implicit values that provide `ClassTags` for the reflection classes. These are abstract in the interface but are later filled in to provide ClassTags for the either the runtime reflection or macros entities, depending on the use.
