TAO中 “>>=“预算符 的含义

[fp2001]

TAO中的">>="运算符的含义是什么？好象不是右移吧？

我在程序中定义了

navigatingEvent* navigating;
//其结构如下：
struct  navigatingEvent
{
  typedef navigatingEvent_var _var_type;
  typedef navigatingEvent_out _out_type;
  
  
  ::CORBA::Double ifheading;
  ::CORBA::Double ifvertiangle;
  ::CORBA::Double ifhoriangle;
  ::CORBA::Double ibheading;
  ::CORBA::Double ibvertiangle;
  ::CORBA::Double ibhoriangle;
  ::CORBA::Double relativespeed;
  ::CORBA::Double absolutespeed;
  ::CORBA::Double northspeed;
  ::CORBA::Double eastspeed;
  ::CORBA::Double longitude;
  ::CORBA::Double latitude;
  ::CORBA::Double anglespeedx;
  ::CORBA::Double anglespeedy;
  ::CORBA::Double anglespeedz;
  ::CORBA::Double hacceleration;
  ::CORBA::Double vertipitchangle;
  ::CORBA::Double horipitchangle;
  ::CORBA::Double ifupdowndist;
  ::CORBA::Double ifupdownspeed;
  ::CORBA::Double ibupdowndist;
  ::CORBA::Double ibupdownspeed;
  ::CORBA::Double depth;
  ::CORBA::Double distance;
  ::CORBA::ULong status;
};
//同时有一个定义
const CORBA::Any &event

if(event >>= navigating）//报错

/*
navigatingEventConsumer.cpp:33: error: no match for 'operator>>=' in 'event >>= navigating'
d:/ACE_wrappers/TAO/tao/AnyTypeCode/Any.h:137: note: candidates are: CORBA::Boolean CORBA::Any::operator>>=(ACE_InputCDR::to_boolean) const
*/

但是如果我把
if(event >>= navigating）
改为
if(event >>= navigating->ifheading）//随便应用一个成员
却可以通过。
我只想if(event >>= navigating）这么操作，不知道如何更改？

注意数据类型!!!

[baihacker]

event >>= (int)navigating;

好像event >>= navigating->ifheading右边是double,照理说也应该不能通过...不知道你这里的Double是不是double

楼上的可否说的清楚点啊？给个方法啊

[fp2001]

后面还有很多类似这样干的错误我没有贴出来

CORBA::Boolean CORBA::Any::operator>>=(ACE_InputCDR::to_octet) const
d:/ACE_wrappers/TAO/tao/AnyTypeCode/Any.h:139: note: CORBA::Boolean CORBA::Any::operator>>=(ACE_InputCDR::to_char) const
d:/ACE_wrappers/TAO/tao/AnyTypeCode/Any.h:140: note: CORBA::Boolean CORBA::Any::operator>>=(ACE_InputCDR::to_wchar) const
d:/ACE_wrappers/TAO/tao/AnyTypeCode/Any.h:141: note: CORBA::Boolean CORBA::Any::operator>>=(ACE_InputCDR::to_string) const
d:/ACE_wrappers/TAO/tao/AnyTypeCode/Any.h:142: note: CORBA::Boolean CORBA::Any::operator>>=(ACE_InputCDR::to_wstring) const

改成event >>= (int)navigating; 也不行啊，结构体变量这么可以转换成int类型呢？

自己提供对应的类型转换操作.

晕,自己根据所要的进行重载就行了.

还是有点不太懂啊....
楼上的能不能在细点？偶是新人，谢谢哈~~~
