| * UncheckedRE is a subclass of RE that allows programmers an easier means |
| * of programmatically precompiling regular expressions. It is constructed |
| * and used in exactly the same manner as an instance of the RE class; the |
| * only difference is that its constructors do not throw REException. |
| * Instead, if a syntax error is encountered during construction, a |
| * RuntimeException will be thrown. |
| * <P> |
| * Note that this makes UncheckedRE dangerous if constructed with |
| * dynamic data. Do not use UncheckedRE unless you are completely sure |
| * that all input being passed to it contains valid, well-formed |
| * regular expressions for the syntax specified. |
