This is demonstrated using the ExceptionHandler class, which again adopts a singleton design pattern.
使用exceptionhandler类可以展示这一点，该类也采用了singleton设计模式。
A simple optimization to this code would be to apply the Singleton design pattern to class Empty, because every instance of Empty is identical.
这段代码的一个简单优化是对empty类应用同一个设计类型，因为每一个Empty的实例都是同样的。
Hence, SignalTranslator adopts a singleton design pattern.
因此，SignalTranslator采用了singleton设计模式。
You will design the object as a singleton (this design pattern will limit this object to a single instance) and have the appropriate retrieve and store methods to manipulate the cache.
您将把对象设计为一个单子实例 （singleton）（这个设计模式将把这个对象限制在一个单个实例中）并使用合适的检索和存储方法对高速缓存进行操作。
The singleton is a useful design pattern for allowing only one instance of your class, but common mistakes can inadvertently allow more than one instance to be created.
单例模式是一种非常有用的设计模式，它允许你的类对外只提供一个实例，但是常犯的错误在于不止一个实例被创建。
Since it is thread safe by design, you might cache it in a public static final variable, or wrap it in a singleton pattern after creation for later access.
因为根据设计它是线程安全的，创建它之后可以把它缓存在一个公共静态最终变量中，或者包装在单实例模式中以供以后访问。
Don't over - "design pattern" applications - Sometimes it's just easier to write a simple algorithm than it is to incorporate a singleton or facade pattern.
不要过于注重程序的“设计模式”。有时候，写一个简单的算法，要比引入某种模式更容易。
The singleton pattern is probably one of the most often used OOP design patterns; it restricts the number of object instances of a class to one.
单例模式可能是最常用的OOP设计模式之一了；它限制了一个类的对象实例数只能为1。
