getEntityById

protected EntityInterface getEntityById(EntityID id)

getEntityByName

getFailureSeverity

protected final JobFailureSeverity getFailureSeverity()

getJob

public static Job getJob(String job, JobFailureSeverity severiy, EntityInterface entity, Transaction<? extends TransactionContainer> transaction)

Create a Job object with the given parameters.

This static method is used by other classes to create Job objects, instead of the private constructor.

Returns:: The generated Job object.

getRequestId

protected String getRequestId()

getTarget

public abstract JobTarget getTarget()

getTransaction

public Transaction<? extends TransactionContainer> getTransaction()

getTransactionStage

public TransactionStage getTransactionStage()

getUser

protected Subject getUser()

hashCode

public int hashCode()

init

public final Job init(JobFailureSeverity severity, EntityInterface entity, Transaction<? extends TransactionContainer> transaction)

isSubType

protected final boolean isSubType(EntityInterface child, EntityInterface targetParent)

Check if an entity (‘child’) is a direct or indirect child of another entity (‘targetParent’).

This assumes that the parent has either an id (persistent or temporary) or a name.

If the targetParent is not in the set of parents of the child, this method iterates through the direct parents of the child.

If both entities are part of this transaction, they are resolved within this transaction. Otherwise they are fetched from the database backend or the whole evaluation takes place in the backend (if both have persistent ids and are not part of this transaction).

If both entities have the same id or name, the return value is true without any further checks.

Parameters:

child – the child entity
targetParent – the parent entity

Throws:

Message –

Returns:

true iff targetParent is a direct or indirect parent of the child or when the ids or names match.

isValidSubType

protected final boolean isValidSubType(EntityID child, EntityID parent)

public List<Job> loadJobs(EntityInterface entity, Transaction<? extends TransactionContainer> transaction)

loadPermanentContainerJobs

public static List<Job> loadPermanentContainerJobs(Transaction<?> transaction)

Return those matching jobs which are annotated with the “loadAlways” attribute.

Returns:: A list with the jobs.

loadStandardJobs

public List<Job> loadStandardJobs(EntityInterface entity, Transaction<? extends TransactionContainer> transaction)

resolve

protected EntityInterface resolve(EntityInterface entity)

Resolve an entity (which might only be specified by it’s name or id) to its full representation (with properties, parents and all).

Parameters:

entity – the entity to be resolved.

Throws:

EntityWasNotUniqueException – if the resolution failed due to ambiguity of the name.

Returns:

the resolved entity.
