# Beethoven: A library for making Java bytecode instrumentation easier
|
|
|
|
The point of this library is to offer a simple, annotation-driven way to instrument classes.
|
|
What this means is that a user of this library should never have to see
|
|
so much as a byte. Everything should be abstracted to the level of classes,
|
|
methods and fields.
|
|
|
|
## Version 2
|
|
|
|
### Implemented
|
|
|
|
* Per-instruction method frame state analysis tools
|
|
|
|
* Method insertion
|
|
|
|
* Method replacement
|
|
|
|
* In-place method appending
|
|
* Accepting return value as argument
|
|
* Overwriting return value
|
|
|
|
* In-place method prepending
|
|
|
|
* Automatic injection of INVOKEDYNAMIC lambda targets
|
|
|
|
### TODO
|
|
|
|
* Better tests
|
|
|
|
* Execution path optimization (e.g. remove unnecessary GOTOs) |
