Detailed Description

Interface of an add info container object (used by geometry objects)

Managing attributes, layout and views is a core feature of the DM library. Please refer to the Managing Attributes section for implementation concepts and to the examples section (attribute handling) for further details.

Member Function Documentation

cloneAddInfoView() [1/2]

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

cloneAddInfoView() [2/2]

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

getAsDoubleByView()

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

setAddInfoView()

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
