Class Token
represents one path of execution and maintains a pointer to a node in the ProcessDefinition. Most common way to get a hold of the token objects is with ProcessInstance.getRootToken() or ProcessInstance.findToken(String).
在流程定义中表现一个执行路径和维持一个指示器给一个节点。
ProcessInstance.getRootToken()
ProcessInstance.findToken(String)
signal()
provides a signal to the token. this method activates this token and leaves the current state over the default transition.
准备一个信号给标记。这个方法激活这个标记并且离开当前的状态越过缺省的跃迁。
------------------------------------
Class ProcessInstance
is one execution of a ProcessDefinition. To create a new process execution of a process definition, just use the ProcessInstance(ProcessDefinition).
是一个流程定义的执行。
ProcessInstance(ProcessDefinition)
---------------------------------------
Class ProcssDefinition
创建一个ProcessDefinition
parseParResource(String parResource)
parseParZipInputStream(ZipInputStream zipInputStream)
parseXmlInputStream(InputStream inputStream)
parseXmlReader(Reader reader)
parseXmlResource(String resource)
parseXmlString(String string)
-----------------------------
Class ContextInstance
maintains all the key-variable pairs for a process instance. You can obtain a ContextInstance from a processInstance from a process instance like this :
ProcessInstance processInstance = ...;
ContextInstance contextInstance = processInstance.getContextInstance();
为流程实例维持所有的key-variable对。
ContextInstance contextInstance = ProcessInstance.getContextInstance();
contextInstance.setVariable("amount",new Integer(500));
contextInstance.setVariable("reason","I met my deadline");

任务节点：
<task-node name="t">
<task name="change nappy">
<assignment class="org.jbpm.tutorial.taskmgmt.NappyAssignmentHandler"/>
</task>
<transition to="end">
</task-node>
TaskInstance taskInstance = (TaskInstance)processInstance.getTaskMgmtInstance().getTaskInstances().iterator().next();
taskInstance.end(); //标志这个任务已经结束
