定义常量指针的语句格式为:const类型 * 变量 (或 类型 const * 变量) 如: int i = 3; int j = 5; constint * p= &i; 则: p = &j; /* 正确,p可以被重新赋值 */ *p = j; /* 错误,因为他改变的是p所指向的变量的值。*/
被存储对象的常量指针。
XMLStreamReader 接口基本上定义了基于指针的 API(虽然标记常量在其超类型 XMLStreamConstants 接口中定义)。
The XMLStreamReader interface essentially defines the cursor-based API (though the token constants are defined in its super-type, interface XMLStreamConstants).
常量池引用被与指向内部数据结构的指针取代,成功的或者某种工作方式会被一种简单的形式替代。
Constant pool references are replaced with Pointers to internal data structures, operations that always succeed or always work a certain way are replaced with simpler forms.
