A job object provides properties and methods of obtaining the output message, job scheduling plan time, and job execution time of the previous node in a job.

Properties and Methods

**Table 1** **Property description**
Property	Type	Description
name	String	Name of the job.
planTime	java.util.Date	Job scheduling plane time, that is, the time configured for periodic scheduling, for example, to schedule a job at 1:01 a.m. every day.
startTime	java.util.Date	Job execution time. It may be the same as or later than the planTime (because the job engine is busy).
eventData	String	Message obtained from the DIS stream when the event-driven scheduling is used.
projectId	String	ID of the project where DLF is located.

**Table 2** Method description
Method	Description
String getNodeStatus(String nodeName)	Obtains the running status of a specified node. If the node runs properly, success is returned. If the node fails to run, fail is returned. For example, the following condition can be used to determine whether a node is successfully executed: #{(Job.getNodeStatus("test")) == "success" }
String getNodeOutput(String nodeName)	Obtains the output of a specified node. This method can only obtain the output of the previous dependent node. Currently, only the output of the Rest Client node, that is, the returned message of the REST request, can be obtained.
String getParam(String key)	Obtains a job parameter.
String getPlanTime(String pattern)	Obtains the plan time character string in a specified pattern. Pattern indicates the date and time mode. For details, see Date and Time Mode.
String getYesterday(String pattern)	Obtains the time character string of the day before the plan time. Pattern indicates the date and time mode. For details, see Date and Time Mode.
String getLastHour(String pattern)	Obtains the time character string of last hour before the plan time. Pattern indicates the date and time mode. For details, see Date and Time Mode.
String getRunningData(String nodeName)	Obtains the data recorded during the running of a specified node. This method can only obtain the output of the previous dependent node. Currently, only the DLI job ID recorded during the running of the DLI SQL node can be obtained. For example, to obtain the job ID in the third statement of DLI node DLI_INSERT_DATA, run the following command: #{JSONUtil.path(Job.getRunningData("DLI_INSERT_DATA"),"jobIds[2]")}
String getInsertJobId(String nodeName)	Returns the job ID in the first DLI Insert SQL statement of the specified DLI SQL or Transform Load node. If the nodeName parameter is not specified, the job ID in the first DLI Insert SQL statement of the DLI SQL node is obtained. If the job ID cannot be obtained, the null value is returned.

Example

The expression used to obtain the output of node test in the job is as follows:

#{Job.getNodeOutput("test")}
