类 DoWhile

java.lang.Object

cn.feiliu.taskflow.sdk.workflow.def.tasks.Task<DoWhile>

cn.feiliu.taskflow.sdk.workflow.def.tasks.DoWhile

所有已实现的接口:

ILoopTask<DoWhile>

public class DoWhile
extends Task<DoWhile>
implements ILoopTask<DoWhile>

do while 可以在循环中执行一组任务，直到条件不再满足 例如：${workflow.input.loopCount} 为循环遍历条件表达式

构造器	说明
DoWhile(String taskReferenceName, int loopCount)	Similar to a for loop, run tasks for N times
DoWhile(String taskReferenceName, PathExpression expression)
DoWhile(String taskReferenceName, String expression)	Execute tasks in a loop determined by the condition set using condition parameter.

方法概要

修饰符和类型	方法	说明
DoWhile	childTask(Task<?> task)	添加子任务
String	getLoopCondition()
List<? extends Task>	getLoopTasks()
DoWhile	setLoopCondition(String condition)	设置循环条件表达式(目前仅支持javascript)
void	updateWorkflowTask(FlowTask workflowTask)	Override this method when the sub-class should update the default WorkflowTask generated using Task.toWorkflowTask()

构造器详细资料

DoWhile

public DoWhile(String taskReferenceName,
               String expression)

Execute tasks in a loop determined by the condition set using condition parameter. The loop will continue till the condition is true

参数:

taskReferenceName -

expression - ${workflow.input.loopCount} 要求数据类型为Number类型

DoWhile

public DoWhile(String taskReferenceName,
               PathExpression expression)

DoWhile

public DoWhile(String taskReferenceName,
               int loopCount)

Similar to a for loop, run tasks for N times

参数:

taskReferenceName -

loopCount -

方法详细资料

childTask

public DoWhile childTask(Task<?> task)

从接口复制的说明: ILoopTask

添加子任务

指定者:

childTask 在接口中 ILoopTask<DoWhile>

返回:

setLoopCondition

public DoWhile setLoopCondition(String condition)

设置循环条件表达式(目前仅支持javascript)

参数:

condition -

返回:

getLoopCondition

public String getLoopCondition()

getLoopTasks

public List<? extends Task> getLoopTasks()

updateWorkflowTask

public void updateWorkflowTask(FlowTask workflowTask)

从类复制的说明: Task

Override this method when the sub-class should update the default WorkflowTask generated using Task.toWorkflowTask()

覆盖:

updateWorkflowTask 在类中 Task<DoWhile>
