  • Method Details

    • getContext

      @MaybeNull @Enhance private static Object getContext()
      A proxy for java.security.AccessController#getContext that is activated if available.
      Returns:
      The current access control context or null if the current VM does not support it.

    • doPrivileged

      @Enhance private static <T> T doPrivileged(PrivilegedAction<T> action, @MaybeNull Object context)
      A proxy for java.security.AccessController#doPrivileged that is activated if available.
      Type Parameters:
      T - The type of the action's resolved value.
      Parameters:
      action - The action to execute from a privileged context.
      context - The access control context or null if the current VM does not support it.
      Returns:
      The action's resolved value.

    • readResolve

      private Object readResolve()
      Resolves this instance after deserialization to assure the access control context is set.
      Returns:
      A resolved instance of this instance that includes an appropriate access control context.

    • onLoad

      public void onLoad(Class<?> type)
      Callback that is invoked on the creation of an instrumented type. If the loaded type initializer is alive, this method should be implemented empty instead of throwing an exception.
      Specified by:
      onLoad in interface LoadedTypeInitializer
      Parameters:
      type - The manifestation of the instrumented type.

    • isAlive

      public boolean isAlive()
      Indicates if this initializer is alive and needs to be invoked. This is only meant as a mark. A loaded type initializer that is not alive might still be called and must therefore not throw an exception but rather provide an empty implementation.
      Specified by:
      isAlive in interface LoadedTypeInitializer
      Returns:
      true if this initializer is alive.
