Detaches this (optionally) and grows to accommodate the free space for n elements at the required side. The side is determined from pos.

data pointer can be provided when the caller knows that data points into range [this->begin(), this->end()). In case it is, *data would be updated so that it continues to point to the element it was pointing to before the data move. if data does not point into range, one can/should pass nullptr.

Similarly to data, old, pointer to a default-constructed QADP, can be provided when the caller expects to e.g. copy the data from this to itself:

QList<T> list(5);
qsizetype pos = getArbitraryPos();
list.insert(pos, list.begin(), list.end());

The default rule would be: data and old must either both be valid pointers, or both equal to nullptr.

◆ tryReadjustFreeSpace()

template<class T >

bool QArrayDataPointer< T >::tryReadjustFreeSpace	(	QArrayData::GrowthPosition	pos,
		qsizetype	n,
		const T **	data = `nullptr`
	)

inline

Attempts to relocate [begin(), end()) to accommodate the free space for n elements at the required side. The side is determined from pos.

Returns true if the internal data is moved. Returns false when there is no point in moving the data or the move is impossible. If false is returned, it is the responsibility of the caller to figure out how to accommodate the free space for n elements at pos.

This function expects that certain preconditions are met, e.g. the detach is not needed, n > 0 and so on. This is intentional to reduce the number of if-statements when the caller knows that preconditions would be satisfied.
