The VariantBasedNode class. More...

Detailed Description

template<typename... Args>
class score::VariantBasedNode< Args >

The VariantBasedNode class.

A node which can hold a single data element at the time. All the arguments passed to Args are potential data member.

Additionally, a special tag InvisibleRootNodeTag is added to serve as root element, since this is necessary in the case of QAbstractItemModel.

For instance, VariantBasedNode<int, QString> will have three possible data types: InvisibleRootNode, int, QString.
