io.earcam.instrumental.proxy.handler

Class NoopInvocationHandler

java.lang.Object

io.earcam.instrumental.proxy.handler.NoopInvocationHandler

All Implemented Interfaces:

Serializable, InvocationHandler

public class NoopInvocationHandler
extends Object
implements InvocationHandler, Serializable

Use the static instance NOOP_INVOCATION_HANDLER. Create instances only where you want/need the Object.toString() to be distinct. If near-NOOP functionality required, then compose NOOP_INVOCATION_HANDLER as the delegate for PartialInvocationHandler. Not quite NOOP: 1. honours equals by reference of proxy 2. honours hashCode as system identity of proxy 3. toString outputs system identity of proxy and this instance of NoopInvocationHandler 4. returns default values for primitives and null for Objects 5. Does NOT honour default methods on interfaces - this is achievable via composition with the PartialInvocationHandler
