TaskFlowJob	validateJob(TaskFlowJob job) Validate a job object after the job has been parsed by the scheduler.
TaskFlowJob	validateJob(TaskFlowJob job, Scheduler scheduler, SchedulerSpaceInterface space, String sessionId) Validate a job object which may contain variables which need ModelValidatorContext to validate (e.g., PA:CREDENTIAL, PA:GLOBAL_FILE, PA:USER_FILE), after the job has been parsed by the scheduler.

Method Detail

validateJob

void validateJob(InputStream jobInputStream)
          throws JobValidationException

Throws:

JobValidationException - if the job is not valid

validateJob

TaskFlowJob validateJob(TaskFlowJob job)
                 throws JobValidationException

Validate a job object after the job has been parsed by the scheduler. Example of use: variable model validation.

Parameters:

job - job object to validate

Returns:

if the validator eventually made some modifications to the job, return a new version

TaskFlowJob validateJob(TaskFlowJob job,
                        Scheduler scheduler,
                        SchedulerSpaceInterface space,
                        String sessionId)
                 throws JobValidationException

Validate a job object which may contain variables which need ModelValidatorContext to validate (e.g., PA:CREDENTIAL, PA:GLOBAL_FILE, PA:USER_FILE), after the job has been parsed by the scheduler. Example of use: variable model validation.

Parameters:

job - job object to validate

scheduler - scheduler instance which can give the access to the third-party credentials

space - SchedulerSpaceInterface instance which can give the access to check data space files

sessionId - current session for validating jobs with CATALOG_OBJECT variables

Returns:

if the validator eventually made some modifications to the job, return a new version

Throws:

JobValidationException - if the job is not valid
