自定义流程

流程包括：事件、活动、流、节点

事件

**Event：流程的状态，无条件执行

属性：id、name

起始
<startEvent id="***" name="***"     />
结束
<endEvent id="***" name="***"     />

活动

activity：单个的任务

属性：id、name、URI

子元素1：input 属性：name、type、UIR

子元素2：output 属性：name、type、UIR

如：决策服务

<activity id="decide1" name="决策服务1" URI="www.baidu.com">
 　　<input name="Strategy1.xls" type="File" UIR="www.google.com/1" />
 　　<input name="Result.properties" type="File" UIR="www.google.com/2" />
　　 <output name="Strategy3.xls" type="File" UIR="www.google.com/3" />
 　　<output name="Result2.properties" type="File" UIR="www.google.com/4" />
 </activity>

流

flow：箭头
属性：id、name、from、to

<process id="..." name="...">
    <startEvent id="startEvent1" name="***"/>
    <activity id="activity1" name="决策服务1" URI="www.baidu.com">
　　　　<input name="Strategy1.xls" type="File" UIR="www.google.com/1" /> 
　　　　<input name="Result.properties" type="File" UIR="www.google.com/2" /> 
　　　　<output name="Strategy3.xls" type="File" UIR="www.google.com/3" /> 
　　　　<output name="Result2.properties" type="File" UIR="www.google.com/4" /> 
　　</activity> 
　　<endEvent id="endEvent1" name="***"/> 
　　<flow id="flow1" name="..." from="startEvent1" to="decide1" />
　　<flow id="flow2" name="..." from="decide1" to="endEvent1" /> 
</process>

节点：

Node：支路的交点，控制流向

parallelNode并行节点
属性：id，name

<process id="..." name="...">
    <!--起始事件-->
    <startEvent id="startEvent1" name="Start"/>
    <!--活动1-->
    <activity id="activity1" name="读取策略" URI="www.baidu.com">

        <input name="Result.properties" type="File" UIR="www.google.com/2" />
        <output name="Strategy3.xls" type="File" UIR="www.google.com/3" />
        <output name="Result2.properties" type="File" UIR="www.google.com/4" />
    </activity>
    <!--并行节点-->
    <parallelNode id="parallelNode1" name="" />
    <!--活动2-->
    <activity id="activity2" name="执行检测软件" URI="www.baidu.com">

        <output name="Result2.properties" type="File" UIR="www.google.com/4" />
    </activity>
    <!--活动3-->
    <activity id="activity3" name="输出策略" URI="www.baidu.com">
