Constructor Summary

JobExecution(JobInstance job)
Constructor for transient (unsaved) instances.

JobExecution(JobInstance job, Long id)
Because a JobExecution isn't valid unless the job is set, this constructor is the only valid one from a modelling point of view.

JobExecution(Long id)

Constructor Detail

JobExecution

public JobExecution(JobInstance job,
                    Long id)

Because a JobExecution isn't valid unless the job is set, this constructor is the only valid one from a modelling point of view.

Parameters:

job - the job of which this execution is a part

JobExecution

public JobExecution(JobInstance job)

Constructor for transient (unsaved) instances.

Parameters:

job - the enclosing JobInstance

JobExecution

public JobExecution(Long id)

Method Detail

getEndTime

public Date getEndTime()

setJobInstance

public void setJobInstance(JobInstance jobInstance)

setEndTime

public void setEndTime(Date endTime)

getStartTime

public Date getStartTime()

setStartTime

public void setStartTime(Date startTime)

getStatus

public BatchStatus getStatus()

setStatus

public void setStatus(BatchStatus status)

Set the value of the status field.

Parameters:

status - the status to set

upgradeStatus

public void upgradeStatus(BatchStatus status)

Upgrade the status field if the provided value is greater than the existing one. Clients using this method to set the status can be sure that they don't overwrite a failed status with an successful one.

Parameters:

status - the new status value

getJobId

public Long getJobId()

Convenience getter for for the id of the enclosing job. Useful for DAO implementations.

Returns:

the id of the enclosing job

setExitStatus

public void setExitStatus(ExitStatus exitStatus)

Parameters:

exitStatus -

getExitStatus

public ExitStatus getExitStatus()

Returns:

the exitCode

getJobInstance

public JobInstance getJobInstance()

Returns:

the Job that is executing.

getStepExecutions

public Collection<StepExecution> getStepExecutions()

Accessor for the step executions.

Returns:

the step executions that were registered

createStepExecution

public StepExecution createStepExecution(String stepName)

Register a step execution with the current job execution.

Parameters:

stepName - the name of the step the new execution is associated with

isRunning

public boolean isRunning()

Test if this JobExecution indicates that it is running. It should be noted that this does not necessarily mean that it has been persisted as such yet.

Returns:

true if the end time is null

isStopping

public boolean isStopping()

Test if this JobExecution indicates that it has been signalled to stop.

Returns:

true if the status is BatchStatus.STOPPING

stop

public void stop()

Signal the JobExecution to stop. Iterates through the associated StepExecutions, calling StepExecution.setTerminateOnly().

setExecutionContext

public void setExecutionContext(ExecutionContext executionContext)

Sets the ExecutionContext for this execution

Parameters:

executionContext - the context

getExecutionContext

public ExecutionContext getExecutionContext()

Returns the ExecutionContext for this execution. The content is expected to be persisted after each step completion (successful or not).

Returns:

the context

getCreateTime

public Date getCreateTime()

Returns:

the time when this execution was created.

setCreateTime

public void setCreateTime(Date createTime)

Parameters:

createTime - creation time of this execution.

getLastUpdated

public Date getLastUpdated()

Get the date representing the last time this JobExecution was updated in the JobRepository.

Returns:

Date representing the last time this JobExecution was updated.

setLastUpdated

public void setLastUpdated(Date lastUpdated)

Set the last time this JobExecution was updated.

Parameters:

lastUpdated -

getFailureExceptions

public List<Throwable> getFailureExceptions()

addFailureException

public void addFailureException(Throwable t)

Add the provided throwable to the failure exception list.

Parameters:

t -

getAllFailureExceptions

public List<Throwable> getAllFailureExceptions()

Return all failure causing exceptions for this JobExecution, including step executions.

Returns:

List containing all exceptions causing failure for this JobExecution.

toString

public String toString()

Overrides:

toString in class Entity

addStepExecutions

public void addStepExecutions(List<StepExecution> stepExecutions)

Add some step executions. For internal use only.

Parameters:

stepExecutions - step executions to add to the current list
