[omniORB] RE: omniORB-list Digest, Vol 78, Issue 1

[Amit Kumar]

Hi All,

I have got the solution to my problem. The idl compilation has to be done
with -Wba option. That generates the corresponding overloaded operator code
for >>=. For a quick reference you may visit the section 11.1.3  "Inserting
and Extracting Constructed Types from an Any" in the link
http://omniorb.sourceforge.net/omni41/omniORB/omniORB011.html 

Greetings,
Amit

Hello All,

 

I am passing a structure as "any" argument in a function. Also, I am trying
to extract the same within the function body. But I am getting error at the
compilation time itself. Details as follows:

 

 //Function Body

 void myFunction(CORBA::Any& data)

{

   Information * localInfo; // "Information" is a structure defined in the
IDL .  "ID" and "name" are the two members of this structure.

   list<CORBA::Any*> myList;

   myList.push_back(new CORBA::Any(data)); //I am storing the data in a list
for some other use

   myList.front() >>=  localInfo;

}

 

 

I am getting following compilation error for the function.

 

error: invalid operands of types `CORBA::Any*' and `Information*' to binary
`operator>>'

in evaluation of `operator>>=(class CORBA::Any*, struct Information*)'

 

 

I am using the structure and function call as below:

 

 long ID_No = 10;

 CORBA::Any myName;

 myName <<= "Amit" ;    

 Information * myInfo;  // "Information" is a structure defined in the IDL .
"ID" and "name" are the two members of this structure.

 myInfo->ID = (CORBA::ULong) ID_No;

 myInfo->raw_data = myName;

 CORBA::Any myAny;

 myAny <<= myInfo;

 myFunction(myAny); //Function call

 

Please help me to resolve this issue.

 

Thanks and Regards,

Amit
