Interface CommandLineRedirection

public interface CommandLineRedirection

Redirection for handling of entered command lines. Normally, entered command lines are parsed and handled immediately by the appropriate handlers. An implementation of this interface (once registered to the CommandContext), will be intervening after the parsing step and will be taking the handling of the command lines from that point. Until it decides to unregister from the CommandContext.
