Method Detail

getStepName

String getStepName()

Get step name

Returns:

value of 'id' attribute from

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.

Returns:

job 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
