/**
|

|
|
* 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 {@code null} argument to a
|
||
|
|
* method in any class or interface in this package will cause a
|
||
|
|
* {@link java.lang.NullPointerException NullPointerException} to be
|
||
|
|
* thrown.
