Java 之 invokedynamic

简述

Add a new bytecode, invokedynamic, that supports efficient and flexible execution of method invocations in the absence of static type information.

-- JSR 292 - Description

 

First let us describe invokedynamic. It is a 5-byte instruction similar to invokeinterface, but it has no built-in scope, receiver, or dispatch behavior. 

-- Bytecodes meet Combinators: invokedynamic on the JVM

调用

Part 1. method handles

Part 2. Method handles can be constructed, combined, and invoked in all kinds of useful patterns.

Part 3: a bootstrap method (BSM)
