  • Method Details

    • getStepName

      String getStepName()
      Get step name.
      Returns:
      value of 'id' attribute from <step>

    • getTransientUserData

      Object getTransientUserData()
      The getTransientUserData method returns a transient data object belonging to the current Job XML execution element.
      Returns:
      user-specified type

    • setTransientUserData

      void setTransientUserData(Object data)
      The setTransientUserData method stores a transient data object into the current batch context.
      Parameters:
      data - is the user-specified type

    • getStepExecutionId

      long getStepExecutionId()
      The getStepExecutionId method returns the current step's execution id.
      Returns:
      step execution id

    • getProperties

      Properties getProperties()

      The getProperties method returns the step level properties specified in a job definition.

      A couple notes:
      • There is no guarantee that the same Properties object instance is always returned in the same (step) scope.
      • Besides the properties which are defined in JSL within a child <properties> element of a <step> element, the batch runtime implementation may choose to include additional, implementation-defined properties.
      Returns:
      step level properties

    • getPersistentUserData

      Serializable getPersistentUserData()
      The getPersistentUserData method returns a persistent data object belonging to the current step. The user data type must implement java.util.Serializable. This data is saved as part of a step's checkpoint. For a step that does not do checkpoints, it is saved after the step ends. It is available upon restart.
      Returns:
      user-specified type

    • setPersistentUserData

      void setPersistentUserData(Serializable data)
      The setPersistentUserData method stores a persistent data object into the current step. The user data type must implement java.util.Serializable. This data is saved as part of a step's checkpoint. For a step that does not do checkpoints, it is saved after the step ends. It is available upon restart.
      Parameters:
      data - is the user-specified type

    • getBatchStatus

      BatchStatus getBatchStatus()
      The getBatchStatus method returns the current batch status of the current step. This value is set by the batch runtime and changes as the batch status changes.
      Returns:
      batch status string

    • getExitStatus

      String getExitStatus()
      The getExitStatus method simply returns the exit status value stored into the step context through the setExitStatus method or null.
      Returns:
      exit status string

    • setExitStatus

      void setExitStatus(String status)
      The setExitStatus method assigns the user-specified exit status for the current step. When the step ends, the exit status of the step is the value specified through setExitStatus. If setExitStatus was not called or was called with a null value, then the exit status defaults to the batch status of the step.
      Parameters:
      status - string

    • getException

      Exception getException()
      The getException method returns the last exception thrown from a step level batch artifact to the batch runtime.
      Returns:
      the last exception

    • getMetrics

      Metric[] getMetrics()
      The getMetrics method returns an array of step level metrics. These are things like commits, skips, etc.
      Returns:
      metrics array
