void vtkSMSelectionHelper::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		[virtual]

Reimplemented from vtkSMObject.

static vtkSMProxy* vtkSMSelectionHelper::NewSelectionSourceFromSelection	(	vtkSMSession *	session,
		vtkSelection *	selection
	)		[static]

Given a selection, returns a proxy for a selection source that has the ids specified by it. This source can then be used as input to a vtkExtractSelection filter. CAVEAT: Make sure to specify the connection id for the server on which the selection was performed. This method can only handle 3 types of selection FRUSTUM, INDICES and GLOBALIDS. We can easily change this to handle all other types of selection but that's not required currently and hence we not adding that code.

static void vtkSMSelectionHelper::NewSelectionSourcesFromSelection	(	vtkSelection *	selection,
		vtkSMProxy *	view,
		vtkCollection *	selSources,
		vtkCollection *	selRepresentations
	)		[static]

static vtkSMProxy* vtkSMSelectionHelper::ConvertSelection	(	int	outputType,
		vtkSMProxy *	selectionSourceProxy,
		vtkSMSourceProxy *	dataSource,
		int	outputport
	)		[static]

Given the ContentType for an output vtkSelection, this create a new source proxy generating the selection, the input selectionSourceProxy is used to fill the default values for created selection source.

static bool vtkSMSelectionHelper::MergeSelection	(	vtkSMSourceProxy *	output,
		vtkSMSourceProxy *	input,
		vtkSMSourceProxy *	dataSource,
		int	outputport
	)		[static]

Updates output to be a combination of (input | output) if the two selection sources are mergeable. Returns true if merge successful. dataSource and outputport are needed if a conversion is needed to make the input expandable to the type of the output.

static void vtkSMSelectionHelper::ConvertSurfaceSelectionToVolumeSelectionInternal	(	vtkIdType	connectionID,
		vtkSelection *	input,
		vtkSelection *	output,
		int	global_ids
	)		[static, protected]
