Constructor & Destructor Documentation

DataUploaderDownloader	(	unsigned int	uploadQueueSize,
		FullQueueBehavior	fullQueueBehavior,
		NewDatumAvailableBehavior	newDatumAvailableBehavior
	)

inline

Constructor.

Parameters

uploadQueueSize	the size of the upload queue. If the b parameter is IncreaseQueueSize, this is the initial size and the queue will never be shorter than this. The queue will always have at least one element (even if this is set to 0)
fullQueueBehavior	the behavior of the uploader when the queue is full
newDatumAvailableBehavior	the behavior of the downloader when a new datum arrives. In this constructor this must be either NoNotification or NoNotificationBlocking, otherwise an exception is thrown

Definition at line 881 of file dataexchange.h.

DataUploaderDownloader	(	unsigned int	uploadQueueSize,
		FullQueueBehavior	fullQueueBehavior,
		QObject *	o
	)

inline

Constructor.

This constructor sets the NewDatumAvailableBehavior of the downloader to QtEvent

Parameters

uploadQueueSize	the size of the upload queue. If the b parameter is IncreaseQueueSize, this is the initial size and the queue will never be shorter than this. The queue will always have at least one element (even if this is set to 0)
fullQueueBehavior	the behavior of the uploader when the queue is full
o	the object to send notifications to when a new datum is available. This must not be NULL.

Definition at line 903 of file dataexchange.h.

DataUploaderDownloader	(	unsigned int	uploadQueueSize,
		FullQueueBehavior	fullQueueBehavior,
		NewDatumNotifiable< DownloadedData > *	o
	)

inline

Constructor.

This constructor sets the NewDatumAvailableBehavior of the downloader to Callback

Parameters

uploadQueueSize	the size of the upload queue. If the b parameter is IncreaseQueueSize, this is the initial size and the queue will never be shorter than this. The queue will always have at least one element (even if this is set to 0)
fullQueueBehavior	the behavior of the uploader when the queue is full
o	the object whose callback has to be called when a new datum is available. This must not be NULL.
