Constructor Detail

DefinitionValidator

public DefinitionValidator(DefinitionAccessor definitionAccessor,
                           JobManager jobManager,
                           ObjectStoreService objectStoreService)

Parameters:

definitionAccessor - accessor for reading user-submitted or configured definitions.

jobManager - needed for accessing task generators needed for validation

objectStoreService - the reference to the object store service.

Method Detail

validateJob

public void validateJob(JobDefinition job)
                 throws InvalidConfigException,
                        PersistenceException

check the the workflow referenced by this job.

Parameters:

job - job definition

Throws:

InvalidConfigException - validation error.

PersistenceException - error reading definition(s).

validateWorkflow

public void validateWorkflow(WorkflowDefinition workflow)
                      throws InvalidConfigException,
                             PersistenceException

check if workflow definition is valid.

Parameters:

workflow - workflow definition

Throws:

InvalidConfigException - validation error.

PersistenceException - error accessing storage

validateBucket

public void validateBucket(BucketDefinition bucketDefinition)
                    throws InvalidConfigException,
                           PersistenceException

check if bucket definition is valid.

Parameters:

bucketDefinition - bucket definition

Throws:

InvalidConfigException - validation error.

PersistenceException - the bucket names cannot be retrieved.

validateBucketWorkflows

public void validateBucketWorkflows(BucketDefinition bucketDefinition)
                             throws PersistenceException,
                                    InvalidConfigException

Check if the bucket can be safely added without compromising data integrity. I.e. if there is an existing workflow definition that already references a bucket with the same name, it must still be valid after the update.

Parameters:

bucketDefinition - The bucket to check

Throws:

PersistenceException - error reading workflow definition(s)

InvalidConfigException - error adding definition due to dependency constraints

checkRemoveWorkflow

public void checkRemoveWorkflow(java.lang.String name)
                         throws InvalidConfigException,
                                PersistenceException

Check if the workflow can be safely removed without compromising data integrity. I.e. if there is an existing job definition that still references this workflow, it must not be removed.

Parameters:

name - The name of the workflow to check

Throws:

PersistenceException - error reading job definition(s)

InvalidConfigException - error deleting definition due to dependency constraints

checkRemoveBucket

public void checkRemoveBucket(java.lang.String name)
                       throws InvalidConfigException,
                              PersistenceException

Check if the bucket can be safely removed without compromising data integrity. I.e. if there is an existing workflow definition that still references this bucket, it must not be removed.

Parameters:

name - The name of the bucket to check

Throws:

PersistenceException - error reading workflow definition(s)

InvalidConfigException - error deleting definition due to dependency constraints

checkJobRemove

public void checkJobRemove(java.lang.String jobName)
                    throws JobManagerException

Checks if the job can be removed.

Parameters:

jobName - The name of the job to be removed.

Throws:

JobManagerException - Some error occurred while checking if job is currently running.
