IAppJobListener Interface for components that need to be notified about changes in Jobs.

CObjectManagerEngineAction(IAppJob *job)

bool Execute(CRef< CPrefetchRequest > token)

IAppJob & GetIAppJob(void)

CObjectManagerEngine(unsigned max_threads=3)

CObjectManagerEngine.

void PrefetchNotify(CRef< objects::CPrefetchRequest > token, EEvent event)

virtual void ResumeJob(IAppJob &job)

virtual void RequestCancel()

asyncronous request all jobs to Cancel

IAppJobEngineListener * m_Listener

objects::CPrefetchManager m_PrefetchManager

virtual void CancelJob(IAppJob &job)

Cancel job in the engine If job is not running yet - just remove from the pending queue otherwise use...

virtual TJobState GetJobState(IAppJob &job) const

virtual void StartJob(IAppJob &job, IEngineParams *params=NULL)

If Engine cannot start the Job and exception shall be thrown.

virtual void ShutDown()

stop any background threads and free resources associated with the Engine

virtual void SetListener(IAppJobEngineListener *listener)

For "active" mode set a Listener that will be notified when the state of a Job changes.

virtual void SuspendJob(IAppJob &job)

virtual bool IsActive()

Returns true if Engine supports "active" model i.e.

IAppJobEngineListener - receives notifications about changes in job state.

#define NCBI_THROW(exception_class, err_code, message)

Generic macro to throw an exception, given the exception class, error code and message string.

void Warning(CExceptionArgs_Base &args)

virtual void RequestCancel()=0

RequestCancel() is called to notify the Job that it shall exit Run() function ASAP.

EJobState

Job states (describe FSM)

virtual void OnEngineJobStateChanged(IAppJob &job, TJobState new_state)=0

@ eEngineBusy

Engine is busy, caller needs to re-try the operation.

#define END_NCBI_SCOPE

End previously defined NCBI scope.

#define BEGIN_NCBI_SCOPE

Define ncbi namespace.

EStatus

Status of the task.

@ eIdle

has not been placed in queue yet

@ eQueued

in the queue, awaiting execution

@ eExecuting

being executed

@ eFailed

failure during execution

@ eCompleted

executed successfully

@ eCanceled

canceled - possible only if canceled before processing was started or if method Execute() returns res...

@ eCanceled

Request canceled.
