vector of messages in inet

[matin]

hi all,

i need to create a vector of messages that is shared between all nodes.(global) therefore i wrote the following code:

in my BasicApp.h:

static std::list<PublicationMsg*> tranmitionPubMsgArray;

in my BasicApp.cc:

Define_Module(BasicApp);

PublicationMsg* BasicApp::tranmitionPubMsgArray;

....

but when i build my simulation,this errors appears:

Error1:  'BasicApp::tranmitionPubMsgArray' has a previous declaration as 'std::list<PublicationMsg*> BasicApp::tranmitionPubMsgArray'

Error2: declaration of 'std::list<PublicationMsg*> BasicApp::tranmitionPubMsgArray' outside of class is not definition [-fpermissive]

Error3: conflicting declaration 'PublicationMsg* BasicApp::tranmitionPubMsgArray'

what is the problem? please guide me. thanks in advance.

[matin]

please any one help me. thanks.

Matin,

    remove the last line of your code ("PublicationMsg* BasicApp::

tranmitionPubMsgArray") and test, please

Matin,

   you are correct. I just forgot to test referecing the list.

 In your BasicApp.cc put this:

std::list<PublicationMsg*> BasicApp::tranmitionPubMsgArray;

thanks a lot. it is correct. thanks.

excuse me how can i read the messages in this list? i can read the message in vector (e.g. tranmitionPubMsgArray[a]->getDestAddress()) 

but i dont now how can i read the elements in the list. thanks for your helps.

thanks a lot. it is correct. thanks.

To iterate over a list you can use either the for_each statement [using functors (C++03) or closures (C++11)] [1] or using a default for statement like below

for(std::list<PublicationMsg*>::iterator i = tranmitionPubMsgArray.begin(); i != tranmitionPubMsgArray.end(); i++) {

    // 'i' is a reference to each position of PublicationMsg*

}
