Class Advice.Dispatcher.Inlining.Resolved.AdviceMethodInliner.ExceptionTableSubstitutor

  • Enclosing class:
    Advice.Dispatcher.Inlining.Resolved.AdviceMethodInliner
    protected class Advice.Dispatcher.Inlining.Resolved.AdviceMethodInliner.ExceptionTableSubstitutor
extends org.objectweb.asm.MethodVisitor
    A label substitutor allows to visit an advice method a second time after the exception handlers were already written. Doing so, this visitor substitutes all labels that were already created during the first visit to keep the mapping consistent. It is not required to resolve labels for non-code instructions as meta information is not propagated to the target method visitor for advice code.
