Class DefaultMemberInvoker

java.lang.Object

io.fluxzero.common.reflection.DefaultMemberInvoker

All Implemented Interfaces:

MemberInvoker

public class DefaultMemberInvoker
extends Object
implements MemberInvoker

Default implementation of MemberInvoker using high-performance method handle-based invocation.

This implementation attempts to convert reflective member access into a compiled lambda expression via LambdaMetafactory and MethodHandle, avoiding the overhead of standard Java reflection.

Key Features

• Caches compiled lambda invokers for reuse
• Falls back to reflection if lambda creation is not possible
• Supports methods, constructors, and fields (read/write)
• Supports up to 10 parameters per method (beyond which it falls back)

Usage example:

Method m = MyClass.class.getDeclaredMethod("doSomething", String.class);
MemberInvoker invoker = DefaultMemberInvoker.asInvoker(m);
Object result = invoker.invoke(myInstance, "value");
