java.lang.Object
  java.io.Reader
      com.metamatrix.script.shell.ReaderInterceptor

All Implemented Interfaces:

java.io.Closeable, java.lang.Readable

public class ReaderInterceptor
extends java.io.Reader

This class used in conjunction with BeanShell, to hijack the System.in and write a wrapper on top it,so that any commands entered in its console be passed through this code before any thing else happens. This will let us write code such as "select * from foo" on the bean shell command line, and we can intercept and issue right beanshell command to execute the same.
