FlowSimpleInfo Struct¶

Sample¶

{
    "flowId":"2809",
    "flowName":"21",
    "nodeId":"f_2809",
    "isVirtual":false,
    "x":0.0125,

Parameters¶

Name	Data Type	Description
flowId	String	The workflow ID.
flowName	String	The workflow name.
nodeId	String	The ID of the node that is part of other workflows.
isVirtual	Boolean	true = the workflow is a virtual workflow false = the workflow is not a virtual workflow
x	Double	The x-axis of the node on the configuration panel of the workflow.

Parameters¶

Name	Data Type	Description
taskName	String	The task name.
x	Double	The x-axis of the task on the configuration panel.
y	Double	The y-axis of the task on the configuration panel.
taskId	String	The task ID.
