IGTLDevice overwrites the device name set in the message
Closed, WontfixPublic


I figured out that the IGTLDevice overwrites the device name set in the message itself. That was probably programmed by myself because I did not understand it better. There is no good reason why you should overwrite this.

Imagin you have two different kind of messages that you set different names ("TransformMessage1", "PositionMessage1"). The receiver will not see this names but the device that sent it, e.g. "IGTLServer".

I suggest that we adapt the current version from

// add the name of this device to the message

to something like this

std::string mergedNames = msg->GetDeviceName() + " sent by " + this->GetName());
msg->SetDeviceName( mergedNames.c_str() );

You find this in
unsigned int mitk::IGTLDevice::SendMessagePrivate(igtl::MessageBase::Pointer msg,

igtl::Socket::Pointer socket)
