Class COM.stevesoft.pat.Transformer

java.lang.Object
  |
  +--COM.stevesoft.pat.Transformer

public class Transformer

extends java.lang.Object

This feature can be used to prevent transformations from occurring in certain regions. For example, if I add the rule s'//.*'$&' and then add the rule s/hello/goodbye/ the Transformer will replace "hello" with "goodbye" except when it occurs inside a double-slash style of comment. The transformation on the comment goes first, does nothing, and precludes transformation on the same region of text as the s/hello/goodbye/ rule.

So far, at least, this class does not have the capability of turning into a giant robot :-)
