Can the straight lines of the graph in the following code be changed to polylines using the Fluent Builder API?Make the image more beautiful?
code:
BpmnModelInstance modelInstance = Bpmn.createProcess()
.startEvent()
.userTask()
.parallelGateway(“fork”)
.serviceTask()
.parallelGateway(“join”)
.moveToNode(“fork”)
.userTask()
.connectTo(“join”)
.moveToNode(“fork”)
.scriptTask()
.connectTo(“join”)
.endEvent()
.done();
