[jbpm-dev] build a process with groovy

I wrote a very easy groovy class to build a pvm process, it's funny. - class: import groovy.util.BuilderSupport; /** * ProcessBuilder * @author Kent Chen * */ public class ProcessBuilder extends BuilderSupport { def processDefinition def unsuredFlows = [] def createNode(Object name) { return createNode(name, null, null) } def createNode(Object name, Object value) { return createNode(name, null, value) } def createNode(Object name, Map attributes) { return createNode(name, attributes, null) } def createNode(Object name, Map attributes, Object value) { if(name == "process"){ processDefinition = new ProcessDefinitionImpl(name:value) return processDefinition } if(name == "activity"){ def activity = new ActivityImpl(name:attributes.name ,activityBehaviour:attributes.activityBehaviour) processDefinition.addActivity(activity) return activity } if(name == "transition"){ def transition = current.createOutgoingTransition() transition.name = attributes.name unsuredFlows.add(new UnsuredFlow(transition:transition,to: attributes.to)) return "transition" } if(name == "initial"){ return "initial" } return name; } def void setParent(Object parent, Object child) { } def void nodeCompleted(Object parent, Object node) { if(node == "initial"){ processDefinition.setInitial(parent) } if(parent == null){ for(unsuredFlow in unsuredFlows){ def activity = processDefinition.findActivity(unsuredFlow.to) activity.addIncomingTransition(unsuredFlow.transition) } } } } class UnsuredFlow { TransitionImpl transition String to } - usage: def builder = new ProcessBuilder() builder.process("helloProcess"){ activity(name:"1",activityBehaviour:new TakeBehaviour()){ initial() transition(name:"t1",to:"2") transition(name:"t2",to:"3") } activity(name:"2",activityBehaviour:new WaitState()) activity(name:"3",activityBehaviour:new WaitState()){ transition(name:"t3",to:"4") } activity(name:"4",activityBehaviour:new WaitState()) } def processInstance = builder.processDefinition.startProcessInstance() processInstance.signal("t2"); processInstance.signal(); processInstance.signal();
