SparkILoop

class SparkILoop extends LoopCommands with Logging

The Scala interactive shell. It provides a read-eval-print loop around the Interpreter class. After instantiation, clients should call the main() method.

If no in0 is specified, then input will come from the console, and the class will attempt to provide input editing feature such as input history.
