Create bytebuddy interface for safe bytecode manipulation between multiple processors #10

Closed Dragovorn closed 3 years ago

ByteBuddy manipulation should be allowed by all annotation processors, the pre-requisite to this is to allow processors to safely edit potentially the same method. This should be done by adding a new step to all of the annotation processors with some way of providing 'advice' or direct changes to incoming bytebuddy operation on the associated class. Desired flow:

Run Class Level Annotations
Run Field Level Annotations
Run Method Level Annotations
Construct Wrapped Class

A thought on method wrapping compatibility-- when producing wrapped methods it may be possible to generate a method interceptor at runtime and to use that to 'stitch' together multiple method interceptor classes in bytebuddy, the performance and memory impact of this will have to be scrutinized though.

This might be possible by using a custom delegator engine that acts as a middleman, i.e. WinryDelegator, which then has delegators registered to it, which are then executed on delegation.
