Method Detail

executeCommand

protected void executeCommand()

Overrides:

executeCommand in class BaseImagesCommand<T extends ImagesContainterParametersBase>

ConcreteCreateTask

protected Guid ConcreteCreateTask(AsyncTaskCreationInfo asyncTaskCreationInfo,
                      VdcActionType parentCommand)

Overrides:

ConcreteCreateTask in class CommandBase<T extends ImagesContainterParametersBase>

AdditionalImageRemoveTreatment

protected void AdditionalImageRemoveTreatment(DiskImage snapshot)

Overrides:

AdditionalImageRemoveTreatment in class BaseImagesCommand<T extends ImagesContainterParametersBase>

getImageId

protected Guid getImageId()

During trying image new snapshot created to image, user wish to try. If user wish to work with image, he tried - he will work with snapshot instead of the original image. In this case ImageId will be not the original image Id, But the snapshots. We assuming that this case can occure only during Trying image. So there are two images map to same drive will appiare in db and active is the one - user will work with. Inactive will be removed

Overrides:

getImageId in class BaseImagesCommand<T extends ImagesContainterParametersBase>
