public abstract class ExceptionTableSensitiveMethodVisitor extends org.objectweb.asm.MethodVisitor
A MethodVisitor that adds a callback after visiting the exception table of a method.

  • Field Details

    • trigger

      private boolean trigger
      true if the exception table callback was already triggered.

  • Constructor Details

    • ExceptionTableSensitiveMethodVisitor

      protected ExceptionTableSensitiveMethodVisitor(int api, org.objectweb.asm.MethodVisitor methodVisitor)
      Creates an exception table sensitive method visitor.
      Parameters:
      api - The ASM API version.
      methodVisitor - The delegating method visitor.

  • Method Details

    • considerEndOfExceptionTable

      private void considerEndOfExceptionTable()
      Considers if the end of the exception table was reached.

    • onAfterExceptionTable

      protected abstract void onAfterExceptionTable()
      Invoked after the exception table was visited. Typically, the exception table is visited by ASM at the beginning of a method. It is however possible that a user adds exception table entries at a later point. Normally, this is however not meaningful use of ASM.
