    EXPERIMENTAL

    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:

    EXPERIMENTAL

    The trait that defines flag sets and operations on them.

    Flags are used to provide modifiers for abstract syntax trees that represent definitions via the flags field of scala.reflect.api.Trees#Modifiers. Trees that accept modifiers are:

    For example, to create a class named C one would write something like:

    ClassDef(Modifiers(NoFlags), TypeName("C"), Nil, ...)

    Here, the flag set is empty.

    To make C private, one would write something like:

    ClassDef(Modifiers(PRIVATE), TypeName("C"), Nil, ...)

    Flags can also be combined with the vertical bar operator (|). For example, a private final class is written something like:

    ClassDef(Modifiers(PRIVATE | FINAL), TypeName("C"), Nil, ...)

    The list of all available flags is defined in scala.reflect.api.FlagSets#FlagValues, available via scala.reflect.api.FlagSets#Flag. (Typically one writes a wildcard import for this, e.g. import scala.reflect.runtime.universe.Flag._).

    Definition trees are compiled down to symbols, so flags on modifiers of these trees are transformed into flags on the resulting symbols. Unlike trees, symbols don't expose flags, but rather provide isXXX test methods (e.g. isFinal can be used to test finality). These test methods might require an upcast with asTerm, asType or asClass as some flags only make sense for certain kinds of symbols.

    Of Note: This part of the Reflection API is being considered as a candidate for redesign. It is quite possible that in future releases of the reflection API, flag sets could be replaced with something else.
