Using a regular expression engine, it is easy to test if a string matches the pattern.
通过使用正则表达式引擎，很容易测试出字符串是否与模式匹配。
The regular expression engine has a simple and clean interface, which basically requires you to learn two new classes and one new interface.
该正则表达式引擎有一个简单且清晰的接口，它主要要求您了解两个新类和一个新接口。
Looking at just the leaf node, this resembles the source code to a fair extend. Next this is translated into the machine code of the regular expression engine.
它的叶子节点就好像一种略加扩展的源代码，而下一步便是把它转换为正则表达式引擎所使用的机器码。
If you are using a regular expression pattern that has already been defined in another static method call, the regular expression engine will retrieve it from the cache.
如果您使用其他静态方法呼叫中已定义的规则运算式模式，规则运算式引擎就会从快取中撷取这个规则运算式模式。
Unicode character class specifiers, arbitrary code execution inside a pattern, flag toggles, conditional expressions, and many other features were added to the regular expression engine.
Unicode字符集、模式内任意代码操作、flagtoggles、条件表达式以及其他特征都被添加到正则表达式库中。
This package offers an engine that performs operations on character sequences by interpreting patterns, a pattern being a compiled expression of a regular expression.
该包提供了一个引擎，可以通过解释模式对字符序列执行操作，即模式成为正则表达式的编译表达式。
One of the reasons I decided to develop XI now was to experiment with the new regular expression (regex) engine that's built into JDK 1.4.
我决定现在开发XI的原因之一是想要用已构建到JD K 1.4中的新的正则表达式(regex)引擎进行实验。
