编译器内联的getter和setter的概率 [英] Probability of getters and setters getting inlined by the compiler

问题描述

我的问题很简单：

问： getter / setter方法将被编译器Java？（显然没有明确的答案，但其他信息将不胜感激）

Q: What is the chance that a getter / setter method will get inlined by the compiler in Java?
(Obviously there isn't a definite answer to this, but other information would be appreciated)

额外：理解总是有机会编译器（标准和JIT）将决定一个方法内联，并且当涉及到getters和setters这通常是程序员想要的。

Extra: I understand there is always a chance the compiler (Standard and JIT) will decide to make a method inline, and when it comes to getters and setters this is usually what the programmer wants.

提前感谢。

推荐答案

对优化可以有微不足道的影响，
作为优化发生在运行时。

The compiler (javac) tend to have negligible impact on optimization, as optimization happens at run time.

从JIT是的，它可能会内联迟到或迟到代码的使用有多重，因此可以首先看到函数调用开销，但是当getter / setter被频繁调用时，它被内联。

As of the JIT yes,it will probably inline either sooner or later.depending on how heavily the code is used, so a function call overhead may be seen at first, but when the getter/setter has been called sufficiently often then it is inlined.
