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).
在流程定義中表現(xiàn)一個(gè)執(zhí)行路徑和維持一個(gè)指示器給一個(gè)節(jié)點(diǎn)。
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.
準(zhǔn)備一個(gè)信號(hào)給標(biāo)記。這個(gè)方法激活這個(gè)標(biāo)記并且離開(kāi)當(dāng)前的狀態(tài)越過(guò)缺省的躍遷。
------------------------------------
Class ProcessInstance
is one execution of a ProcessDefinition. To create a new process execution of a process definition, just use the ProcessInstance(ProcessDefinition).
是一個(gè)流程定義的執(zhí)行。
ProcessInstance(ProcessDefinition)
---------------------------------------
Class ProcssDefinition
創(chuàng)建一個(gè)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();
為流程實(shí)例維持所有的key-variable對(duì)。
ContextInstance contextInstance = ProcessInstance.getContextInstance();
contextInstance.setVariable("amount",new Integer(500));
contextInstance.setVariable("reason","I met my deadline");

任務(wù)節(jié)點(diǎn)：
<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(); //標(biāo)志這個(gè)任務(wù)已經(jīng)結(jié)束
