With the new interface modeling functionality, it is possible to model the interfaces of the processes and connecting the connectors to specific interfaces of the process when a process is used on a diagram. For this purpose, there is a new property in process step and element types called "Interface relations" and a new behavior "Allow attached interfaces" that enables defining the interface relations. There are separate input and output interface relations that can be defined. The "Interface element" behavior found in previous versions of QPR Suite has now been renamed to "Cross-model interface" behavior.

 

Process steps and element types have new interface-specific behavior options "Input interface" and "Output interface", which are used for modeling the interfaces of processes and when the process is used on a diagram, the connectors can be connected to specific interfaces of the process.

 

 

Here, a subprocess element has two attached interfaces, an input one and an output one:

 

 

The input and output interfaces are shown on the 'Subprocess Element' diagram:

 

 

From the Diagram View Settings, it is also possible to define whether interfaces are hidden or shown on the diagram.
