Class ByteBuddyPatchRegistry

java.lang.Object

me.tamkungz.nilkit.tooling.bytebuddy.ByteBuddyPatchRegistry

public final class ByteBuddyPatchRegistry
extends Object

Composes and installs ByteBuddyPatch instances.

Two execution paths are supported:

• NilLoader pre-load transformation, requiring no self-attach.
• Instrumentation/AgentBuilder with retransformation for already loaded classes.

This makes the same patch definition usable both like a traditional Mixin (before class definition) and like a runtime agent when Instrumentation exists.

Method Details

register

public ByteBuddyPatchRegistry register(ByteBuddyPatch patch)

unregister

public boolean unregister(String id)

clear

public void clear()

snapshot

public List<ByteBuddyPatch> snapshot()

isEmpty

public boolean isEmpty()

installNilLoaderBridge

public void installNilLoaderBridge()

Installs one catch-all NilLoader transformer. Register this during premain/hijack, before NilLoader closes transformer registration.

Patches themselves remain dynamic: a patch registered later still affects classes that have not yet been defined.

transformBytes

public byte[] transformBytes(ClassLoader loader,
 String binaryClassName,
 byte[] originalBytes)

Transforms a raw class file without loading the class. Useful for NilLoader and for tests/tools that patch byte arrays directly.

installOn

public ByteBuddyPatchRegistry.Installation installOn(Instrumentation instrumentation)

Installs all registered patches as one retransformation-capable Byte Buddy agent. The returned handle can later be reset.
