1、使用句柄访问方式 如果使用句柄访问方式,Java堆中会划分出一块内存来作为句柄池,reference中存储的就是对象的句柄地址,而句柄中包含了对象实例数据和类型数据各自的具体地址信息。使用句柄方式最大的好处就是reference中存储的是稳定的句柄地址,在对象被移动(垃圾收集时移动对象是非常普遍的行为)时只会改变句柄中的实...

动态链接(Dynamic Linking) 概念 动态链接、方法返回地址、附加信息 : 有些地方被称为帧数据区 每一个栈帧内部都包含一个指向运行时常量池中该栈帧所属方法的引用。包含这个引用的目的就是为了支持当前方法的代码能够实现动态链接(Dynamic Linking)。比如:invokedynamic指令 在Java源文件被编译到字节码文件中时,所有的...
Linking involves not only the replacement of symbolic references with direct ones, it also involves checking for correctness and permission. As mentioned in Chapter 7, "The Lifetime of a Class," the checking of symbolic references for existence and access permission (one aspect of the full verifi...
The linker forobjects. A dynamic linker is a main objects when using Dynalink, it coordinates linking of call sites with linkers of available language runtimes that are represented byobjects (you only need to deal with these if you are yourself implementing a language runtime with its own objec...
动态链接(Dynamic Linking) 每一个栈帧内部都包含一个指向运行时常量池或该栈帧所属方法的引用。包含这个引用的目的就是为了支持当前方法的代码能够实现动态链接。比如invokedynamic指令 在Java源文件被编译成字节码文件中时,所有的变量和方法引用都作为符号引用(symbolic Refenrence)保存在class文件的常量池里。比如:描述...
Language runtime implementors will normally implement the linking logic for their own language as one or more GuardingDynamicLinker classes. They will typically set them as prioritized linkers in the DynamicLinkerFactory they configure for themselves, and maybe also set some as fallback linkers to ...
