-/**
- * An REMatchEnumeration enumerates regular expression matches over a
- * given input text.  You obtain a reference to an enumeration using
- * the <code>getMatchEnumeration()</code> methods on an instance of
- * RE. 
- *
- * <P>
- *
- * REMatchEnumeration does lazy computation; that is, it will not
- * search for a match until it needs to.  If you'd rather just get all
- * the matches at once in a big array, use the
- * <code>getAllMatches()</code> methods on RE.  However, using an
- * enumeration can help speed performance when the entire text does
- * not need to be searched immediately.
- *
- * <P>
- * 
- * The enumerated type is especially useful when searching on a Reader
- * or InputStream, because the InputStream read position cannot be
- * guaranteed after calling <code>getMatch()</code> (see the
- * description of that method for an explanation of why).  Enumeration
- * also saves a lot of overhead required when calling
- * <code>getMatch()</code> multiple times.
