Detailed Description

An asynchronous job that can be added to and executed by a job server.

Since this class derives from tbb::task it MUST use the the tbb task new operator. Ex: new (tbb::task::allocate_root()) DtAsyncJob(); Note that this class is abstract and cannot actually be instantiated, but all concrete subclasses must also follow this rule.

CTOR.

virtual DtAsyncJob::~DtAsyncJob ( )

Virtual DTOR.

Member Function Documentation

virtual task* DtAsyncJob::execute ( )

virtual

Do not override. Calls onExecute, then onException if there is an exception thrown.

Reimplemented in DtAsyncDetachedJob.

virtual task* DtAsyncJob::onExecute ( )

pure virtual

Called to execute a task.

Implemented in MAKVRinTerra::DtMakePathJob.

virtual task* DtAsyncJob::onException ( )

pure virtual

Called when an exception is caught during execution.

Implemented in MAKVRinTerra::DtMakePathJob.

virtual void DtAsyncJob::tick ( )

virtual

Called each tick.

virtual boost::shared_ptr<DtAsyncJobMapEntry> DtAsyncJob::getEntry ( ) const

pure virtual

Returns the entry associated with this task.

If it is null the task is no longer needed.

Implemented in DtAsyncDetachedJob, and DtAsyncManagedJob.

virtual void DtAsyncJob::setEntry ( boost::shared_ptr< DtAsyncJobMapEntry >  )

pure virtual

Set the job entry.

Implemented in DtAsyncDetachedJob, and DtAsyncManagedJob.

bool DtAsyncJob::cancel ( ) const

virtual

DtAlgorithmManager cancel function.

Reimplemented from DtAlgorithmManager.
