basicStrategy()

QPair< int, VisualizationGroup::ItemConstructor > Visualization::ModelRenderer::basicStrategy ( Item *  parent, Model::Node *  node, int  purpose, int  semanticZoomLevel, std::function< QVector< VisualizationGroup * >((int, int, int))>  option1, std::function< QVector< VisualizationGroup * >((int, int, int))>  option2, std::function< QVector< VisualizationGroup * >((int, int, int))>  option3  )

private

Returns a visualization that is most suitable for the given parameter values.

It uses a priority based approach that first searches for a match according to a function provided as option1. If no match was found it proceeds with option2 then with option3.

bestVisualizationForContext()

QPair< int, VisualizationGroup::ItemConstructor > Visualization::ModelRenderer::bestVisualizationForContext	(	Item *	parent,
		Model::Node *	node,
		int	purpose = -1,

hasVisualization()

bool Visualization::ModelRenderer::hasVisualization	(	int	nodeTypeId,
		int	purpose = 0,
		int	semanticZoomLevel = 0

Returns whether a specific visualization has been registered for nodes of type nodeTypeId and the provided purpose.

render()

Item * Visualization::ModelRenderer::render	(	Item *	parent,
		Model::Node *	node,
		int	purpose = -1,
		int	semanticZoomLevel = -1
	)

Returns an Item which has a parent parent and is a rendering of node.

If purpose is specified (purpose >= 0) it is used as the target purpose when determining an appropriate visualization. Otherwise the purpose of parent is used. If parent is nullptr the default purpose is used.

sync()

bool Visualization::ModelRenderer::sync	(	Item *&	item,
		Item *	parent,
		Model::Node *	node
	)

(Re)renders an item in the context of a parent item.

Returns true is the item was destroyed or rerendered. If nothing happened to the item, the return value is false.
