Member Function Documentation

◆ insertMultiAtEnd()

void QAbstractItemModelPrivate::Persistent::insertMultiAtEnd	(	const QModelIndex &	key,
		QPersistentModelIndexData *	data )

QMultiHash::insert inserts the value before the old value. and find() return the new value. We need insertMultiAtEnd because we don't want to overwrite the old one, which should be removed later

There should be only one instance QPersistentModelIndexData per index, but in some intermediate state there may be severals of PersistantModelIndex pointing to the same index, but one is already updated, and the other one is not. This make sure than when updating the first one we don't overwrite the second one in the hash, and the second one will be updated right later.
