| * Classes for matching character sequences against patterns specified by regular |
| * expressions. |
| * |
| * <p> An instance of the {@link java.util.regex.Pattern} class represents a |
| * regular expression that is specified in string form in a syntax similar to |
| * that used by Perl. |
| * |
| * <p> Instances of the {@link java.util.regex.Matcher} class are used to match |
| * character sequences against a given pattern. Input is provided to matchers via |
| * the {@link java.lang.CharSequence} interface in order to support matching |
| * against characters from a wide variety of input sources. </p> |
| * |
| * <p> Unless otherwise noted, passing a <tt>null</tt> argument to a method |
| * in any class or interface in this package will cause a |
| * {@link java.lang.NullPointerException NullPointerException} to be thrown. |
