Abstract: The Java 7 platform includes the invokedynamic opcode in its virtual machine, a feature that lets programmers define, and dynamically change, the linkage of method call sites and thereby ...
The release also enables invokedynamic optimization by default, a JVM feature long supported by JRuby but previously disabled for most use cases due to overhead concerns. "JRuby 10 runs with full ...
图片 没有无源之水,Java语言层面的特性,除非是纯语法糖,不然一定离不开特定JVM特性的支撑。Lambda是Java8语言特性,那支撑它的便是JVM invokedynamic指令。 上述4种字节码指令各自有不同的使用场景,但是有一个共同的特点:目标方法一定需要在【编译期】确定。
Kotlinx-metadata-jvm 库: kotlinx-metadata-jvm 库现已进入稳定状态 Lambda 函数: Kotlin 2.0.0 引入了一种使用生成 lambda 函数的新默认方法“invokedynamic”,可生成更小的二进制文件。 使用 Apple 平台上的标记(signposts)监控 Kotlin / Native 中的 GC 性能: 以前,开发者只能 ...

我说。 同样的代码,在 Java 11 的环境下,字节码指令是这样的: 看标号为 29 的这行,字节码指令为 invokedynamic,该指令允许由应用级的代码来决定方法解析,所谓的应用级的代码其实是一个方法——被称为引导方法(Bootstrap Method),简称 BSM,BSM 会返回一个 CallSite ...
