Class XThis 
java.lang.Object
bsh.This
bsh.XThis
- All Implemented Interfaces:
- java.lang.Runnable, java.io.Serializable
- class XThis
- extends This
XThis is a dynamically loaded extension which extends This.java and adds
support for the generalized interface proxy mechanism introduced in
JDK1.3. XThis allows bsh scripted objects to implement arbitrary
interfaces (be arbitrary event listener types).
Note: This module relies on new features of JDK1.3 and will not compile
with JDK1.2 or lower. For those environments simply do not compile this
class.
Eventually XThis should become simply This, but for backward compatability
we will maintain This without requiring support for the proxy mechanism.
XThis stands for "eXtended This" (I had to call it something).

toString
public java.lang.String toString()
- Description copied from class:
java.lang.Object
- Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into System.out.println() 55
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a java.lang.RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use "null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
