org.multiverse.instrumentation
Class PreventReinstrumentationInstrumentationPhase

java.lang.Object
  org.multiverse.instrumentation.AbstractInstrumentationPhase
      org.multiverse.instrumentation.PreventReinstrumentationInstrumentationPhase

All Implemented Interfaces:

InstrumentationPhase

public class PreventReinstrumentationInstrumentationPhase
extends AbstractInstrumentationPhase

A control flow InstrumentationPhase responsible for preventing that a class already has been instrumented:

1. If the class already is instrumented, it checks if the compiler name and version match. If not, an error is thrown. Multiverse compilation is not backwards compatible yet.
2. InstrumentationStamp with a instrumentorName and instrumentorVersion based on the provided compiler. So next time this class is going to be re-instrumented, the multiverse instrumentation is skipped or an error is thrown if the instrumentorName/instrumentorVersion don't match.
