Scala example source code file (SymbolTable.scala)

This example Scala source code file (SymbolTable.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Scala source code examples by using tags.

All credit for the original source code belongs to scala-lang.org; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

The SymbolTable.scala Scala example source code

/**
 *  This symbol table trait fills in the definitions so that class information is obtained by refection.
 *  It can be used either from a reflexive universe (class scala.reflect.runtime.JavaUniverse), or else from
 *  a runtime compiler that uses reflection to get a class information (class scala.tools.reflect.ReflectGlobal)

  /** Declares that this is a runtime reflection universe.
   *
   *  This means that we can make certain assumptions to optimize the universe.
   *  For example, we may auto-initialize symbols on flag and annotation requests
   *  (see `shouldTriggerCompleter` below for more details).
   *
   *  On the other hand, this also means that usage scenarios of the universe
   *  will differ from the conventional ones. For example, we have to do additional cleanup
   *  in order to prevent memory leaks: http://groups.google.com/group/scala-internals/browse_thread/thread/eabcf3d406dab8b2.
