[tao-users] How to use a customed StructuredEvent which gener ated from IDL file bewteen publisher and subscriber by Notifycation Servi ces?

[techabc]

the problem solved according to the changelog:

USER VISIBLE CHANGES BETWEEN TAO-2.4.1 and TAO-2.4.2
====================================================

. Fixed some problems with versioned namespaces in the
  tao_idl generated code

. Removed the non-const Any extraction operators which
  are deprecated within the IDL to C++ specification
  for a long time. Reduces footprint and simplifies the
  code. Make sure you are using 'const Foo*' as extraction
  type for Foo instead of 'Foo*'.

>> The remainder_of_body has the type “any”. So you can push what you want

>> For instance if you define in your idl file something as:
>>
>>
>>
>> Typedef long MotionCommand
>>
>> Typdef sequence<MotionCommand> MCmdSeq
>>
>>
>>
>> You then declare in your implementation class a variable of that type:
>>
>>
>>
>> McmdSeq m_cmd;
>>
>>
>>
>> //example
>>
>> m_cmd .length(2);
>>
>> m_cmd[0] = 10;
>>
>> m_cmd[0] = 20;
>>
>>
>>
>> And push it into the event in the supplier:
>>
>>
>>
>> event.remainder_of_body <<= m_cmd
>>
>>
>>
>> then you send the data by using:
>>
>>
>>
>> supplier_1_->send_event (event); // in the subscribe example
>>
>>
>>
>> that will call:
>>
>>
>>
>> proxy_consumer->push_structured_event (event);
>>
>>
>>
>> in the consumer you will do the reverse operation
>>
>>
>>
>> event.remainder_of_body >>= m_cmd;
>>
>>
>>
>> The <<= and >>= conversion operators are generated by the idl compiler.
>>
>>
>>
>> Hope this will help you.
