[gme-users] Creation of a Connection

[Kevin Smyth]

The ConnectionEnds in Connection::create represent the source and
destination of the connection. BON::FCO inherits from ConnectionEnd. For
example:

 

BON::Atom srcClass, dstClass;

Connection conn = Connection::create(BON::Model(currentFCO), srcClass,
dstClass, "Association");

 

For the UML paradigm, ConnectionEnds are equivalent to FCOs, since the
UML paradigm has no refports.

 

An example of a BON2 interpreter is under C:\Program
Files\GME\Paradigms\SF\BON2SFInterpreter, but this interpreter does not
modify the model.

Subject: [gme-users] Creation of a Connection

 

Hello,

 

I am trying to create a Connection from a plug-in, and I've got a
question about the required attributes.

 

I'm using GME 9.12.15, and what I'm trying to do is to mimic a user's
operation that creates an Association or a Composition Connection in the
UML editor that comes with GME.

 

Below is what I've tried. If it is a completely wrong way to do this,
please guide me to the right way ...

 

 

I was able to create other objects by a line of code like:

 

>> Atom atom (Atom::create(m, type));

 

where m is the parent model and type is the metatype of the new Atom.

 

I was able to update its relative ID, name, and attributes later to have
the Atom that I wanted.

 

Now, I'm trying to create a Connection through a similar way, but I
don't know what to pass as attributes to the creator function.

 

Connection Connection::create( const Model& parent, const ConnectionEnd&
srcEnd, const ConnectionEnd& dstEnd, const MON::Connection& meta, const
std::string& strRole )

 

Above is one of the creators of Connection. There are a number of them,
and all of them require a pair of ConnectionEnds as attributes. I don't
get what they are...

 

If there is a piece of example code, would you please let me know where
it is? Or, please let me know what ConnectionEnds are to use this
function to create a Connection.

 

Thank you very much.

 

~Jae
