Function Documentation

qxAsConst() [1/2]

template<typename T >

const T qxAsConst

(

T &&

t

)

Serves the same purpose as qAsConst() (preventing implicitly-shared Qt containers from detaching), but this version works for rvalues, albeit with some efficiency concerns depending on the nature of t.

qxAsConst() [2/2]

template<typename T >

std::add_const< T >::type qxAsConst

(

T &

t

)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Equivalent to qAsConst(T& t).

This overload exists so that qxAsConst can consistently be used everywhere for both lvalues and rvalues, instead of having to employ mixed usage of qxAsConst() and qAsConst().

qxDelete()

template<typename T >

void qxDelete

(

T *&

pointer

)

Calls delete on pointer and then sets it to nullptr .
