org.activiti.workflow.simple.definition.WorkflowDefinition
Allows to create simple workflows through an easy, fluent Java API. For example: WorkflowDefinition workflowDefinition = new WorkflowDefinition() .name("testWorkflow") .description("This is a test workflow") .inParallel() .addHumanStep("first task", "kermit") .addHumanStep("second step", "gonzo") .addHumanStep("thrid task", "mispiggy") .endParallel() .addHumanStep("Task in between", "kermit") .inParallel() .addHumanStep("fourth task", "gonzo") .addHumanStep("fifth step", "gonzo") .endParallel(); Feed this {@link WorkflowDefinition} instance to a {@link WorkflowDefinitionConversion}and it will convert it a to a {@link BpmnModel}, which in it turn can be used to generate valid BPMN 2.0 through the {@link BpmnXMLConverter}. The reason why we're not just using the {@link BpmnModel} and it's related classes to generate bpmn 2.0 xml, is because this class and it's related classes are a layer on top of them, allowing to easily create patterns. Such patterns are for example a parallel block ( {@link ParallelStepsDefinition}) or a choice step. These can be expressed in their {@link BpmnModel} counterpart of course,but these abstraction are much easier to read and use. @author Joram Barrez
