Hi, How can I deactivate RT-component from within the program? For example,
from onExecute, or from other method. An illustrative case is that a user
input toggled a bool variable, which is being checked in onExecute to decide
if to deactivate (NOT exit) the component. Hope to get some help. Thanks.
Hong

Hi,
Are you asking whether the component deactivates itself? Or do you
want to trigger this from outside the component?
You have a choice of using a service port for the trigger, or you can
use a property value that you check from within the onExecute
function.
Cheers,
Hajime

Hello,
This is an example code in C++.
ReturnCode_t RTObject_impl::onExecute(RTC::UniqueId ec_id)
{
: // you code
if (gotoInactiveState)
{
RTC::ExecutionContext_var ec = get_context(ec_id);
if (CORBA::is_nil(ec))
{
ec->deactivate_component(::RTC::RTObject::_duplicate(getObjRef()));
}
}
: // your code
return RTC::RTC_OK;
}
In the next execution tick, onDeactivated() will be called and
RTC will be in the INACTIVE state.
From OpenRTM-aist-1.1.0, getExecutionContext(), deactivate(),
activate() and reset() functions are introduced in DataflowComponentBase.
Best regards,
Noriaki ANDO

Thank you very much, Ando-san, Hajime-san.I had to invert the condition to !CORBA::is_nil(ec) to make it work.Hope I am not doing anything wrong. I don't exactly get the meaning of CORBA::is_null(obj), however the document says it checks if the obj is nil.

Hello
Oh! It's my mistake.
CORBA::is_nil(object) means the object's reference is invalid.
# It's almost same as null pointer in C/C++ or Java.
If CORBA::is_nil(object) == true, you cannot call any operations of the object.

Thank you very much, Ando-san, Hajime-san.
I had to invert the condition to !CORBA::is_nil(ec) to make it work. Hope I am not doing anything wrong. I don't exactly get the meaning of CORBA::is_null(obj), however the document says it checks if the obj is nil.
Regards Hong PS. Apology for the mess of the posts, still getting accustomed to the forum. I hope this one goes to the right place.
