如何能说明从 Java的code条条形码中能否确定一个地方变量? (与商法协会有关)
原标题:How can one tell if a local variable is final from Java bytecode? (Related to BCEL)

哪里有信息,例如,如果一个地方变量是“最终”储存在 Java的编码? 我知道,就田地(全球变量)和方法而言,这些变量和方法见于门槛值,但在地方变量表中看不到等值。

我对这个问题很感兴趣,因为我正在利用商法来检查当地变量是否为最终变量,并且已经找到了在门槛值班的田地、方法和班子。

提前感谢。

最佳回答

汇编者对当地变数的确定性进行了核对,没有将这种变数归入星码。 这一信息在操作时间上是需要的,因此,储存在星号上。

The JVM treats final and non-final local variables in the same way.

问题回答

Short answer - you can t. The final access flag for local variables only tells compiler that variable value can t be reassigned. See section 4.7.13 of the JVM specification.

我不相信你能够确定地方变量的<代码>final;可以通过与<代码>final关键词和比较附则的小型方法加以证明。
