  The main REPL related classes and values are as follows.

  The main REPL related classes and values are as follows. In addition to standard compiler classes Global and Settings, there are:

  History: an interface for session history. Completion: an interface for tab completion. ILoop (formerly InterpreterLoop): The umbrella class for a session. IMain (formerly Interpreter): Handles the evolving state of the session and handles submitting code to the compiler and handling the output. InteractiveReader: how ILoop obtains input. History: an interface for session history. Completion: an interface for tab completion. Power: a repository for more advanced/experimental features.

  ILoop contains { in: InteractiveReader, intp: IMain, settings: Settings, power: Power } InteractiveReader contains { history: History, completion: Completion } IMain contains { global: Global }

1.  abstract class ExtendedThreadMxBean extends ThreadMXBean
   Annotations
     @SuppressWarnings()
2.  class ExternalToolHook extends AnyRef

   This is an external tool hook, it allows an external tool such as YourKit or JProfiler to instrument a particular phase of the compiler.

   This is an external tool hook, it allows an external tool such as YourKit or JProfiler to instrument a particular phase of the compiler. Profilers have hooks to allow starting and stopping profiling on a given method invocation.

   To use add -Yprofile-external-tool (defaults to typer) or -Yprofile-external-tool:<phase> (for a specific compiler phase) to the compiler flags.

   'before' will be called at the start of the target phase and 'after' at the end, allowing custom profiling to be triggered.

7.  sealed abstract class Profiler extends AnyRef
8.  trait ProfilerPlugin extends AnyRef

   Specifies a plugin to the profiler.

   Specifies a plugin to the profiler. This is generated via the ServiceLoader. See java.util.ServiceLoader javadoc for configuration information

   Note: this must generate a java interface only

9.  trait ProfilerPluginRun extends AnyRef

   Generated by ProfilerPlugin, the plugin information for a single run of the compiler
