  86. case class Constant extends internal.SymbolTable.ConstantApi with Product with Serializable

    This "virtual" case class represents the reflection interface for literal expressions which can not be further broken down or evaluated, such as "true", "0", "classOf[List]".

    This "virtual" case class represents the reflection interface for literal expressions which can not be further broken down or evaluated, such as "true", "0", "classOf[List]". Such values become parts of the Scala abstract syntax tree representing the program. The constants correspond to section 6.24 "Constant Expressions" of the Scala language specification.

    Such constants are used to represent literals in abstract syntax trees (the scala.reflect.api.Trees#Literal node) and literal arguments for Java class file annotations (the scala.reflect.api.Annotations#LiteralArgument class).

    Constants can be matched against and can be constructed directly, as if they were case classes:

    assert(Constant(true).value == true)
    Constant(true) match {
      case Constant(s: String) =>  println("A string: " + s)
      case Constant(b: Boolean) => println("A boolean value: " + b)
      case Constant(x) =>          println("Something else: " + x)
    }

    Constant instances can wrap certain kinds of these expressions:

    1. Literals of primitive value classes (Byte, Short, Int, Long, Float, Double, Char, Boolean and Unit) - represented directly as the corresponding type
    2. String literals - represented as instances of the String.
    3. References to classes, typically constructed with scala.Predef#classOf - represented as types.
    4. References to enumeration values - represented as symbols.

    Class references are represented as instances of scala.reflect.api.Types#Type (because when the Scala compiler processes a class reference, the underlying runtime class might not yet have been compiled). To convert such a reference to a runtime class, one should use the runtimeClass method of a mirror such as RuntimeMirror (the simplest way to get such a mirror is using scala.reflect.runtime.currentMirror).

    Enumeration value references are represented as instances of scala.reflect.api.Symbols#Symbol, which on JVM point to methods that return underlying enum values. To inspect an underlying enumeration or to get runtime value of a reference to an enum, one should use a scala.reflect.api.Mirrors#RuntimeMirror (the simplest way to get such a mirror is again scala.reflect.runtime.package#currentMirror).

    Usage example:

    enum JavaSimpleEnumeration { FOO, BAR }
    
    import java.lang.annotation.*;
    @Retention(RetentionPolicy.RUNTIME)
    @Target({ElementType.TYPE})
    public @interface JavaSimpleAnnotation {
      Class<?> classRef();
      JavaSimpleEnumeration enumRef();
    }
    
    @JavaSimpleAnnotation(
      classRef = JavaAnnottee.class,
      enumRef = JavaSimpleEnumeration.BAR
    )
    public class JavaAnnottee {}
    import scala.reflect.runtime.universe._
    import scala.reflect.runtime.{currentMirror => cm}
    
    object Test extends App {
      val jann = typeOf[JavaAnnottee].typeSymbol.annotations(0).javaArgs
      def jarg(name: String) = jann(newTermName(name)) match {
        // Constant is always wrapped into a Literal or LiteralArgument tree node
        case LiteralArgument(ct: Constant) => value
        case _ => sys.error("Not a constant")
      }
    
      val classRef = jarg("classRef").value.asInstanceOf[Type]
                                             // ideally one should match instead of casting
      println(showRaw(classRef))             // TypeRef(ThisType(), JavaAnnottee, List())
      println(cm.runtimeClass(classRef))     // class JavaAnnottee
    
      val enumRef = jarg("enumRef").value.asInstanceOf[Symbol]
                                             // ideally one should match instead of casting
      println(enumRef)                       // value BAR
    
      val siblings = enumRef.owner.typeSignature.declarations
      val enumValues = siblings.filter(sym => sym.isVal && sym.isPublic)
      println(enumValues)                    // Scope{

                                             // }
    
      // doesn't work because of https://issues.scala-lang.org/browse/SI-6459
      // val enumValue = mirror.reflectField(enumRef.asTerm).get
      val enumClass = cm.runtimeClass(enumRef.owner.asClass)
      val enumValue = enumClass.getDeclaredField(enumRef.name.toString).get(null)

    A type function or the type of a polymorphic value (and thus of kind *).

    Before the introduction of NullaryMethodType, a polymorphic nullary method (e.g, def isInstanceOf[T]: Boolean) used to be typed as PolyType(tps, restpe), and a monomorphic one as PolyType(Nil, restpe) This is now: PolyType(tps, NullaryMethodType(restpe)) and NullaryMethodType(restpe) by symmetry to MethodTypes: PolyType(tps, MethodType(params, restpe)) and MethodType(params, restpe)

    Thus, a PolyType(tps, TypeRef(...)) unambiguously indicates a type function (which results from eta-expanding a type constructor alias). Similarly, PolyType(tps, ClassInfoType(...)) is a type constructor.

  413. case class UnApply extends internal.SymbolTable.Tree with internal.SymbolTable.TermTree with internal.SymbolTable.UnApplyApi with Product with Serializable

    Used to represent unapply methods in pattern matching.

    Used to represent unapply methods in pattern matching.

    For example:

    2 match { case Foo(x) => x }

    Is represented as:

    Match(
    Literal(Constant(2)),
    List(
      CaseDef(
        UnApply(
          // a dummy node that carries the type of unapplication to patmat
          // the  here doesn't have an underlying symbol
          // it only has a type assigned, therefore after `resetAllAttrs` this tree is no longer typeable
          Apply(Select(Ident(Foo), newTermName("unapply")), List(Ident(newTermName("")))),
          // arguments of the unapply => nothing synthetic here
          List(Bind(newTermName("x"), Ident(nme.WILDCARD)))),
        EmptyTree,
        Ident(newTermName("x")))))

    Introduced by typer. Eliminated by compiler phases patmat (in the new pattern matcher of 2.10) or explicitouter (in the old pre-2.10 pattern matcher).

    Check well-kindedness of type application (assumes arities are already checked) -- @M

    This check is also performed when abstract type members become concrete (aka a "type alias") -- then tparams.length==1 (checked one type member at a time -- in that case, prefix is the name of the type alias)

    Type application is just like value application: it's "contravariant" in the sense that the type parameters of the supplied type arguments must conform to the type parameters of the required type parameters:

    • their bounds must be less strict
    • variances must match (here, variances are absolute, the variance of a type parameter does not influence the variance of its higher-order parameters)
    • @M TODO: are these conditions correct,sufficient&necessary?

    e.g. class Iterable[t, m[+x <: t]] --> the application Iterable[Int, List] is okay, since List's type parameter is also covariant and its bounds are weaker than <: Int

  362. 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.

    A creator for existential types. This generates:

    tpe1 where { tparams }

    where tpe1 is the result of extrapolating tpe with respect 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.

    The abstraction drops all type parameters that are not directly or indirectly referenced by type tpe1. If there are no remaining type parameters, simply returns result type tpe.

    Given a set rawSyms of term- and type-symbols, and a type tp, produce a set of fresh type parameters and a type so that it can be abstracted to an existential type. Every type symbol T in rawSyms is mapped to a clone. Every term symbol x of type T in rawSyms is given an associated type symbol of the following form:

    type x.type <: T with Singleton

    The name of the type parameter is x.type, to produce nice diagnostics. The Singleton parent ensures that the type parameter is still seen as a stable type. Type symbols in rawSyms are fully replaced by the new symbols. Term symbols are also replaced, except for term symbols of an Ident tree, where only the type of the Ident is changed.

    SLS 3.

    SLS 3.2, Value Types Is the given type definitely a value type? A true result means it verifiably is, but a false result does not mean it is not, only that it cannot be assured. To avoid false positives, this defaults to false, but since Type is not sealed, one should take a false answer with a grain of salt. This method may be primarily useful as documentation; it is likely that !isNonValueType(tp) will serve better than isValueType(tp).

    The raw to existential map converts a raw type to an existential type. It is necessary because we might have read a raw type of a parameterized Java class from a class file.

    Unlike compiler universes, reflective universes can auto-initialize symbols on flag requests.

    scalac wasn't designed with such auto-initialization in mind, and quite often it makes assumptions that flag requests won't cause initialization. Therefore enabling auto-init leads to cyclic errors. We could probably fix those, but at the moment it's too risky.

    Reflective universes share codebase with scalac, but their surface is much smaller, which means less assumptions. These assumptions are taken care of in this overriden shouldTriggerCompleter method.
