Get a combined fragment and operands

To get a combined fragment, use the Fragments property of the ISequenceDiagram object. To get an operand, use the Operands property of the IFragmentShape object.

public void GetFragments(ICommandContext c, ICommandParams p)
{
    ISequenceDiagram sequenceDiagram = c.App.Workspace.CurrentEditor as ISequenceDiagram;
    if (sequenceDiagram == null) return;

    //Get composite fragments
    var fragments = sequenceDiagram.Fragments;

    var no = 1;
    foreach (IFragmentShape fragment in fragments)
    {
        c.App.Output.WriteLine("sample", $"{no}th composite fragment : {fragment.Text}");
        no++;

        //Get operands
        var operands = fragment.Operands;

        foreach (IOperandShape operand in operands)
        {
            c.App.Output.WriteLine("sample", $" operand : {operand.Guard}");
        }
    }
}

About models

For models of composite fragments and operands, we do not provide a dedicated type, so you need to operate them with the IModel type.
