virtual void cloneAddInfoView	(	const AddInfoLayoutHandle &	layout,
		bool	readOnly
	)		const

pure virtual

internal creates a new addinfo object with the provide view layout that refers to the same storage object

for further details see IAddInfo::cloneView

Parameters

[in]	layout	view layout that should be set
[in]	readOnly	flag if the layout of storage object should be changed, in case the view layout is not a true subset of the storage layout

virtual void cloneAddInfoView	(	const AddInfoLayoutHandle &	viewLayout,
		const AddInfoLayoutHandle &	dataLayout
	)		const

pure virtual

internal creates a new addinfo object with the provide view layout and secures that the storage object contains the dataLayout

for further details see IAddInfo::cloneView

Parameters

[in]	viewLayout	view layout that should be set
[in]	dataLayout	defines columns that have to exist in the storage object

virtual bool getAsDoubleByView	(	const AddInfoLayoutHandle &	,
		unsigned	index,
		double &	value
	)		const

pure virtual

optimised variante to access a view column

Returns: true is value is not null otherwise false

virtual void setAddInfoView	(	const AddInfoLayoutHandle &	layout,
		bool	readOnly
	)

pure virtual

applies a certain layout view onto the current addinfo object

for further details see IAddInfo::setView

Parameters

[in]	layout	view layout that should be set
[in]	readOnly	flag if the layout of storage object should be changed, in case the view layout is not a true subset of the storage layout
