Detailed Description

Internal record to implement bookkeeping of the hierarchy in the underlying DataModel.

It enables two main things:

1. provide fast lookups of elements and their relationships
2. have a secondary storage backend so that we can call the pairs of Qt's begin/endFooRows() functions correctly. One Item instance always corresponds to exactly one element in the QAbstractItemModel. However, the Item hierarchy does not necessarily 1-to-1 correspond to the hierarchy in the underlying DataModel.

Public Attributes
Data *	data = nullptr
	Pointer to Data instance in parent model.
Data *	proxyChild = nullptr
	Pointer to the DataGroup::proxyData if data is a DataGroup.
Item *	parent = nullptr
	Pointer to parent node.
std::vector< std::unique_ptr< Item > >	children
	Enumeration of child nodes, unique_ptr so that their addresses are persistent.
ElementType	type = ElementType::Regular
	Type of the underlying Data instance.

Additional Inherited Members
Public Member Functions inherited from ImFusion::SignalReceiver
	SignalReceiver ()=default
	Default constructor.
	SignalReceiver (const SignalReceiver &other)
	Copy constructor, does not copy any existing signal connections from other.
SignalReceiver &	operator= (SignalReceiver rhs)
	Assignment operator, disconnects all existing connections, does not copy any existing signal connections from rhs.
virtual	~SignalReceiver ()
	Virtual destructor disconnects from all connected signals.
Protected Member Functions inherited from ImFusion::SignalReceiver
void	disconnectAll ()
	Disconnects all existing connections.

Member Data Documentation

proxyChild

Data* ImFusion::DataItemModel::Item::proxyChild = nullptr

Pointer to the DataGroup::proxyData if data is a DataGroup.

Will serve as reference dataset instead of data if not null.
