IWorkflowBpmnInterconnection (formcycle: bom 8.4.0 API)

```
public interface IWorkflowBpmnInterconnection
```
A BPMN interconnection between WorkflowBpmnPointRef. Many interconnections together make up a single BpmnEdge. The first element of an interconnection chain that starts a BPMN edge and the last element that ends the BPMN must always be FlowNodeRef. Intermediate elements may be StructuredPartRef.
During the resolution phase at the end of a BPMN diagram creation process, all interconnection elements are assembled into a chain of interconnections, by building an interconnection graph with the (source, target) as edges. The graph is used to link the target of one interconnection element to the source of the next interconnection element. Each chain (=connected component in the interconnection graph) then becomes a single BPMN edge in the final BPMN diagram.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`IWorkflowBpmnInterconnectionData`	`edgeData()`	Additional data for the interconnection that aids in creating the `BPMN edge`.

- Method Detail
  - edgeData
```
IWorkflowBpmnInterconnectionData edgeData()
```
    Additional data for the interconnection that aids in creating the BPMN edge.
    
    Returns:
    
    The additional data for the interconnection.
  - source
```
WorkflowBpmnPointRef source()
```
    The source point of the interconnection. When the source point is a WorkflowBpmnPointRef.FlowNodeRef, it is the start of an interconnection chain that will eventually become a BPMN edge. When it is a WorkflowBpmnPointRef.StructuredPartRef, it must connect to the target() of another interconnection.
    
    Returns:
    
    The source point of the interconnection.
  - target
```
WorkflowBpmnPointRef target()
```
    The target point of the interconnection. When the target point is a WorkflowBpmnPointRef.FlowNodeRef, it is the end of an interconnection chain that will eventually become a BPMN edge. When it is a WorkflowBpmnPointRef.StructuredPartRef, it must connect to the source() of another interconnection that will continue the chain.
    
    Returns:
    
    The target point of the interconnection.
