Interface Console

All Known Implementing Classes:

JLineConsole, PlainConsole

public interface Console

A class named in configuration as the value of python.console must implement this interface, and provide a constructor with a single String argument, to be acceptable during initialization of the interpreter. The argument to the constructor names the encoding in use on the console. Such a class may provide line editing and history recall to an interactive console. A default implementation (that does not provide any such facilities) is available as PlainConsole.
