    • isWrapperFor

      default boolean isWrapperFor(Class<?> iface)
      Tests if this object instance is of the base- or subclass of the iface class. This method is typically used to identify an instance known as an instance of an interface, and the caller wishes to verify if it's really an implementation of a class that in turn implements or specifies the interface iface.
      Parameters:
      iface - The class to check.
      Returns:
      true if the iface class is assignable from this instance class.
