使用参数创建实例

如果通过 com.sun.star.lang.XMultiComponentFactory:createInstanceWithArgumentsAndContext() 和 com.sun.star.lang.XMultiServiceFactory:createInstanceWithArguments() 传送参数来提出服务，则服务必须实现 com.sun.star.lang.XInitialization 接口。第二个服务 my_module.MyService2 将实现它，并将单个字符串作为参数。

  // XInitialization implementation
  void MyService2Impl::initialize( Sequence< Any > const & args )
      throw (Exception)
  {
      if (1 != args.getLength())
      {
          throw lang::IllegalArgumentException(
              OUString( RTL_CONSTASCII_USTRINGPARAM("give a string instanciating this component!") ),
              (::cppu::OWeakObject *)this, // resolve to XInterface reference
              0 ); // argument pos
      }
      if (! (args[ 0 ] >>= m_arg))
      {
          throw lang::IllegalArgumentException(
              OUString( RTL_CONSTASCII_USTRINGPARAM("no string given as argument!") ),
              (::cppu::OWeakObject *)this, // resolve to XInterface reference
              0 ); // argument pos
      }
  }
