public class InputReader

extends java.io.BufferedReader

implements InputSupplier, java.lang.Runnable

The basic user input reader in the console version of omegahat that is parameterized by a PromptSource and allows listeners (such as an Evaluator, command auditor, history list, etc.) to register and be notified of new input. This is frequently run in a different thread.
