    The Scala Reflection API (located in scala-reflect.jar).

    In Scala 2.10.0, the Scala Reflection API and its implementation have an "experimental" status. This means that the API and the docs are not complete and can be changed in binary- and source-incompatible manner in 2.10.1. This also means that the implementation has some known issues.

    The following types are the backbone of the Scala Reflection API, and serve as a good starting point for information about Scala Reflection:

    This trait defines symbols and operations on them.

    Symbols are used to establish bindings between a name and the entity it refers to, such as a class or a method. Anything you define and can give a name to in Scala has an associated symbol.

    Symbols contain all available information about the declaration of an entity (class/object/trait etc.) or a member (vals/vars/defs etc.), and as such are an integral abstraction central to both runtime reflection and macros.

    A symbol can provide a wealth of information ranging from the basic name method available on all symbols to other, more involved, concepts such as getting the baseClasses from ClassSymbol. Other common use cases of symbols include inspecting members' signatures, getting type parameters of a class, getting the parameter type of a method or finding out the type of a field.

    Example usage of runtime reflection; getting a method's type signature:

    scala> import scala.reflect.runtime.universe._
import scala.reflect.runtime.universe._

scala> class C[T] { def test[U](x: T)(y: U): Int = ??? }
defined class C

scala> val test = typeOf[C[Int]].member(TermName("test")).asMethod
test: reflect.runtime.universe.MethodSymbol = method test

scala> test.info
res0: reflect.runtime.universe.Type = [U](x: T)(y: U)scala.Int

    Symbols are organized in a hierarchy. For example, a symbol that represents a parameter of a method is owned by the corresponding method symbol, a method symbol is owned by its enclosing class, a class is owned by a containing package and so on.

    Certain types of tree nodes, such as Ident (references to identifiers) and Select (references to members) expose method symbol to obtain the symbol that represents their declaration. During the typechecking phase, the compiler looks up the symbol based on the name and scope and sets the symbol field of tree nodes.

    For more information about Symbol usage and attached intricacies, see the Reflection Guide: Symbols

MethodSymbolApi

trait MethodSymbolApi extends Universe.TermSymbolApi

The API of method symbols. The main source of information about symbols is the Symbols page.

Class Symbol defines isXXX test methods such as isPublic or isFinal, params and returnType methods for method symbols, baseClasses for class symbols and so on. Some of these methods don't make sense for certain subclasses of Symbol and return NoSymbol, Nil or other empty values.

    The type signature of this symbol.

    This method always returns signatures in the most generic way possible, even if the underlying symbol is obtained from an instantiation of a generic type. For example, signature of the method def map[B](f: (A) => B): List[B], which refers to the type parameter A of the declaring class List[A], will always feature A, regardless of whether map is loaded from the List[_] or from List[Int]. To get a signature with type parameters appropriately instantiated, one should use infoIn.

    Set when symbol has a modifier of the form private[X] or protected[X], NoSymbol otherwise.

    Access level encoding: there are three scala flags (PRIVATE, PROTECTED, and LOCAL) which combine with value privateWithin (the "foo" in private[foo]) to define from where an entity can be accessed. The meanings are as follows:

    PRIVATE access restricted to class only. PROTECTED access restricted to class and subclasses only. LOCAL can only be set in conjunction with PRIVATE or PROTECTED. Further restricts access to the same object instance.

    In addition, privateWithin can be used to set a visibility barrier. When set, everything contained in the named enclosing package or class has access. It is incompatible with PRIVATE or LOCAL, but is additive with PROTECTED (i.e. if either the flags or privateWithin allow access, then it is allowed.)

    The java access levels translate as follows:

    java private: isPrivate && (privateWithin == NoSymbol) java package: !isPrivate && !isProtected && (privateWithin == enclosingPackage) java protected: isProtected && (privateWithin == enclosingPackage) java public: !isPrivate && !isProtected && (privateWithin == NoSymbol)
