Detailed Description

Callback interface for asynchronous jobs.

Used by clients of the CJobManager to receive progress, abort and completion notification of jobs. Clients of small jobs wishing to perform actions on job completion or abort should implement the IJobCallback::OnJobComplete() and/or IJobCallback::OnJobAbort() function. Clients of larger jobs may choose to implement the IJobCallback::OnJobProgress() function in order to be kept informed of progress.

OnJobAbort()

virtual void IJobCallback::OnJobAbort ( unsigned int jobID, CJob * job )

inlinevirtual

An optional callback function used when a job will be aborted.

OnJobAbort is called whenever a job gets aborted before or while being executed. Job's DoWork method will not be called, OnJobComplete will not be called. The job instance will be destroyed by the caller after calling this function.

Parameters

jobID	the unique id of the job (as retrieved from CJobManager::AddJob)
job	the job that has been aborted.

OnJobComplete()

virtual void IJobCallback::OnJobComplete ( unsigned int jobID, bool success, CJob * job )

pure virtual

The callback used when a job completes.

OnJobComplete is called at the completion of the job's DoWork() function, and is used to return information to the caller on the result of the job. On returning form this function the CJobManager will destroy this job.

Parameters

jobID	the unique id of the job (as retrieved from CJobManager::AddJob)
success	the result from the DoWork call
job	the job that has been processed. The job will be destroyed after this function returns

OnJobProgress()

virtual void IJobCallback::OnJobProgress ( unsigned int jobID, unsigned int progress, unsigned int total, const CJob * job )

inlinevirtual

An optional callback function that a job may call while processing.

OnJobProgress may be called periodically by a job during it's DoWork() function. It is used by the job to report on progress.

Parameters

jobID	the unique id of the job (as retrieved from CJobManager::AddJob)
progress	the current progress of the job, out of total.
total	the total amount of work to be processed.
job	the job that has been processed.
