[Ace-users] Re: [ciao-users] Question about creation of facet servant and executor

[Sowayan, Abdullah (N-DUA)]

Santos,

I don't know 100% the answer to your question. But I think every time the container get a request to obtain an object reference to the facet, it will call into your get_foo_facet () method.

Personally speaking, I think you're just asking for trouble here. I usually instantiate the facet into a CCM_IFooFacet_var type (say my_foo_var), and do the following in the get_foo_facet() method

::App::CCM_IFooFacet_ptr Foo_exec_i::get_foo_facet ()
  {
    // Your code here.
   return ::App::CCM_IFooFacet::_duplicate(my_foo_var.in());
  }

That way, everything is clear and safe. There will be one instantiation for the Foo Facet.

Thanks,
Abdul

    SYNOPSIS: Question about creation of facet servant and executor
[Brief description of the problem]

    DESCRIPTION:
[Detailed description of problem.  Don't just say "<blah> doesn't work, here's a fix," explain what our program does to get to the <blah> state. ]

Hi,

I would appreciatte if you can help me clarifying some doubts about facet objects behavior. The get_facet_name in the component executor returns to the container an facet executor. If in my component executor I have a method implemented like that: 

::App::CCM_IFooFacet_ptr Foo_exec_i::get_foo_facet ()
  {
    // Your code here.
   return ( new IFooFacet_exec_i () );
  }

And If I have two receptacles connected to the same component facet by DAnCE using the following deployment content: 

<connection>
    <name>foo_client1</name>
    <internalEndpoint>
      <portName>foo_facet</portName>
      <kind>Facet</kind>
      <instance>Foo-idd</instance> 
    </internalEndpoint>
    <internalEndpoint>
      <portName>foo_rec</portName>
      <kind>SimplexReceptacle</kind>
      <instance>Client1-idd</instance> 
    </internalEndpoint>
  </connection>

<connection>
    <name>foo_client2</name>
    <internalEndpoint>
      <portName>foo_facet</portName>
      <kind>Facet</kind> 
      <instance>Foo-idd</instance>
    </internalEndpoint>
    <internalEndpoint>
      <portName>foo_rec</portName>
      <kind>SimplexReceptacle</kind>
      <instance>Client2-idd</instance>
    </internalEndpoint>
  </connection>

Will I have two diferent servants for the same facet? Will the reference received by the Client1 receptacle point to a different object than that received by Client2? Will it be created one IfooFacet_exec_i executor for each connection? 

Thank you very much.

Santos
