C++ type: QVector<Qt3DInput::QAxis*>
The QVector class is a template class that provides a dynamic array.
QVector<T> is one of Qt's generic container classes. It stores its items in adjacent memory locations and provides fast index-based access.
QList<T>, QLinkedList<T>, QVector<T>, and QVarLengthArray<T> provide similar APIs and functionality. They are often interchangeable, but there are performance consequences. Here is an overview of use cases:
- QVector should be your default first choice. QVector<T> will usually give better performance than QList<T>, because QVector<T> always stores its items sequentially in memory, where QList<T> will allocate its items on the heap unless
sizeof(T) <= sizeof(void*)
and T has been declared to be either aQ_MOVABLE_TYPE
or aQ_PRIMITIVE_TYPE
using Q_DECLARE_TYPEINFO. See the Pros and Cons of Using QList for an explanation. - However, QList is used throughout the Qt APIs for passing parameters and for returning values. Use QList to interface with those APIs.
- If you need a real linked list, which guarantees constant time insertions mid-list and uses iterators to items rather than indexes, use QLinkedList.
Note: QVector and QVarLengthArray both guarantee C-compatible array layout. QList does not. This might be important if your application must interface with a C API.
Note: Iterators into a QLinkedList and references into heap-allocating QLists remain valid as long as the referenced items remain in the container. This is not true for iterators and references into a QVector and non-heap-allocating QLists.
Here's an example of a QVector that stores integers and a QVector that stores QString values:
QVector<int> integerVector; QVector<QString> stringVector;
QVector stores its items in a vector (array). Typically, vectors are created with an initial size. For example, the following code constructs a QVector with 200 elements:
QVector<QString> vector(200);
The elements are automatically initialized with a default-constructed value. If you want to initialize the vector with a different value, pass that value as the second argument to the constructor:
QVector<QString> vector(200, "Pass");
You can also call fill() at any time to fill the vector with a value.
QVector uses 0-based indexes, just like C++ arrays. To access the item at a particular index position, you can use operator[](). On non-const vectors, operator[]() returns a reference to the item that can be used on the left side of an assignment:
if (vector[0] == "Liz") vector[0] = "Elizabeth";
For read-only access, an alternative syntax is to use at():
for (int i = 0; i < vector.size(); ++i) { if (vector.at(i) == "Alfonso") cout << "Found Alfonso at position " << i << endl; }
at() can be faster than operator[](), because it never causes a deep copy to occur.
Another way to access the data stored in a QVector is to call data(). The function returns a pointer to the first item in the vector. You can use the pointer to directly access and modify the elements stored in the vector. The pointer is also useful if you need to pass a QVector to a function that accepts a plain C++ array.
If you want to find all occurrences of a particular value in a vector, use indexOf() or lastIndexOf(). The former searches forward starting from a given index position, the latter searches backward. Both return the index of the matching item if they found one; otherwise, they return -1. For example:
int i = vector.indexOf("Harumi"); if (i != -1) cout << "First occurrence of Harumi is at position " << i << endl;
If you simply want to check whether a vector contains a particular value, use contains(). If you want to find out how many times a particular value occurs in the vector, use count().
QVector provides these basic functions to add, move, and remove items: insert(), replace(), remove(), prepend(), append(). With the exception of append() and replace(), these functions can be slow (linear time) for large vectors, because they require moving many items in the vector by one position in memory. If you want a container class that provides fast insertion/removal in the middle, use QList or QLinkedList instead.
Unlike plain C++ arrays, QVectors can be resized at any time by calling resize(). If the new size is larger than the old size, QVector might need to reallocate the whole vector. QVector tries to reduce the number of reallocations by preallocating up to twice as much memory as the actual data needs.
If you know in advance approximately how many items the QVector will contain, you can call reserve(), asking QVector to preallocate a certain amount of memory. You can also call capacity() to find out how much memory QVector actually allocated.
Note that using non-const operators and functions can cause QVector to do a deep copy of the data. This is due to implicit sharing.
QVector's value type must be an assignable data type. This covers most data types that are commonly used, but the compiler won't let you, for example, store a QWidget as a value; instead, store a QWidget *. A few functions have additional requirements; for example, indexOf() and lastIndexOf() expect the value type to support operator==()
. These requirements are documented on a per-function basis.
Like the other container classes, QVector provides Java-style iterators (QVectorIterator and QMutableVectorIterator) and STL-style iterators (QVector::const_iterator and QVector::iterator). In practice, these are rarely used, because you can use indexes into the QVector.
In addition to QVector, Qt also provides QVarLengthArray, a very low-level class with little functionality that is optimized for speed.
QVector does not support inserting, prepending, appending or replacing with references to its own values. Doing so will cause your application to abort with an error message.

Implementations§
source§impl VectorAxisMutPtr
impl VectorAxisMutPtr
sourcepub fn append(&mut self, l: &VectorAxisMutPtr)
pub fn append(&mut self, l: &VectorAxisMutPtr)
C++ method: void QVector<Qt3DInput::QAxis*>::append(const QVector<Qt3DInput::QAxis*>& l)
This is an overloaded function.
Appends the items of the value vector to this vector.
This function was introduced in Qt 5.5.
See also operator<<() and operator+=().
sourcepub unsafe fn append_unsafe(&mut self, t: &*mut Axis)
pub unsafe fn append_unsafe(&mut self, t: &*mut Axis)
C++ method: void QVector<Qt3DInput::QAxis*>::append(Qt3DInput::QAxis* const & t)
Inserts value at the end of the vector.
Example:
QVector<QString> vector; vector.append("one"); vector.append("two"); QString three = "three"; vector.append(three); // vector: ["one", "two", "three"] // three: "three"
This is the same as calling resize(size() + 1) and assigning value to the new last element in the vector.
This operation is relatively fast, because QVector typically allocates more memory than necessary, so it can grow without reallocating the entire vector each time.
See also operator<<(), prepend(), and insert().
sourcepub fn at<'l0>(&'l0 self, i: c_int) -> &'l0 *mut Axis
pub fn at<'l0>(&'l0 self, i: c_int) -> &'l0 *mut Axis
C++ method: Qt3DInput::QAxis* const & QVector<Qt3DInput::QAxis*>::at(int i) const
Returns the item at index position i in the vector.
i must be a valid index position in the vector (i.e., 0 <= i < size()).
See also value() and operator[]().
sourcepub fn back<'l0>(&'l0 self) -> &'l0 *mut Axis
pub fn back<'l0>(&'l0 self) -> &'l0 *mut Axis
C++ method: Qt3DInput::QAxis* const & QVector<Qt3DInput::QAxis*>::back() const

pub fn back_mut<'l0>(&'l0 mut self) -> &'l0 mut *mut Axis
C++ method: Qt3DInput::QAxis*& QVector<Qt3DInput::QAxis*>::back()
This function is provided for STL compatibility. It is equivalent to last().
sourcepub fn capacity(&self) -> c_int
pub fn capacity(&self) -> c_int
C++ method: int QVector<Qt3DInput::QAxis*>::capacity() const
Returns the maximum number of items that can be stored in the vector without forcing a reallocation.
The sole purpose of this function is to provide a means of fine tuning QVector's memory usage. In general, you will rarely ever need to call this function. If you want to know how many items are in the vector, call size().
sourcepub fn clear(&mut self)
pub fn clear(&mut self)
C++ method: void QVector<Qt3DInput::QAxis*>::clear()
Removes all the elements from the vector.
Note: Until Qt 5.6, this also released the memory used by the vector. From Qt 5.7, the capacity is preserved. To shed all capacity, swap with a default-constructed vector:
QVector<T> v ...; QVector<T>().swap(v); Q_ASSERT(v.capacity() == 0);
or call squeeze().
See also squeeze().
sourcepub fn const_data(&self) -> *const *mut Axis
pub fn const_data(&self) -> *const *mut Axis
C++ method: Qt3DInput::QAxis* const * QVector<Qt3DInput::QAxis*>::constData() const
Returns a const pointer to the data stored in the vector. The pointer can be used to access the items in the vector. The pointer remains valid as long as the vector isn’t reallocated.
This function is mostly useful to pass a vector to a function that accepts a plain C++ array.
See also data() and operator[]().

Example:
QVector<int> vector(10); int *data = vector.data(); for (int i = 0; i < 10; ++i) data[i] = 2 * i;
The pointer remains valid as long as the vector isn't reallocated.
This function is mostly useful to pass a vector to a function that accepts a plain C++ array.
See also constData() and operator[]().
sourcepub fn empty(&self) -> bool
pub fn empty(&self) -> bool
C++ method: bool QVector<Qt3DInput::QAxis*>::empty() const

Inserts value at index position i in the vector. If i is 0, the value is prepended to the vector. If i is size(), the value is appended to the vector.
Example:

Returns the index position of the last occurrence of the value value in the vector, searching backward from index position from. If from is -1 (the default), the search starts at the last item. Returns -1 if no item matched.
Example:
QList<QString> vector; vector << "A" << "B" << "C" << "B" << "A"; vector.lastIndexOf("B"); // returns 3 vector.lastIndexOf("B", 3); // returns 3 vector.lastIndexOf("B", 2); // returns 1 vector.lastIndexOf("X"); // returns -1
This function requires the value type to have an implementation of operator==()

sourcepub unsafe fn op_shl_unsafe<'l0, 'l1>(
&'l0 mut self,
t: &'l1 *mut Axis
) -> &'l0 mut VectorAxisMutPtr
pub unsafe fn op_shl_unsafe<'l0, 'l1>(
&'l0 mut self,
t: &'l1 *mut Axis
) -> &'l0 mut VectorAxisMutPtr
C++ method: QVector<Qt3DInput::QAxis*>& QVector<Qt3DInput::QAxis*>::operator<<(Qt3DInput::QAxis* const & t)
Appends value to the vector and returns a reference to this vector.
See also append() and operator+=().
sourcepub fn pop_back(&mut self)
pub fn pop_back(&mut self)
C++ method: void QVector<Qt3DInput::QAxis*>::pop_back()
This function is provided for STL compatibility. It is equivalent to removeLast().
sourcepub fn pop_front(&mut self)
pub fn pop_front(&mut self)
C++ method: void QVector<Qt3DInput::QAxis*>::pop_front()
This function is provided for STL compatibility. It is equivalent to removeFirst().
sourcepub unsafe fn prepend(&mut self, t: &*mut Axis)
pub unsafe fn prepend(&mut self, t: &*mut Axis)
C++ method: void QVector<Qt3DInput::QAxis*>::prepend(Qt3DInput::QAxis* const & t)
Inserts value at the beginning of the vector.
Example:
QVector<QString> vector; vector.prepend("one"); vector.prepend("two"); vector.prepend("three"); // vector: ["three", "two", "one"]
This is the same as vector.insert(0, value).
For large vectors, this operation can be slow (linear time), because it requires moving all the items in the vector by one position further in memory. If you want a container class that provides a fast prepend() function, use QList or QLinkedList instead.

sourcepub unsafe fn replace(&mut self, i: c_int, t: &*mut Axis)
pub unsafe fn replace(&mut self, i: c_int, t: &*mut Axis)
C++ method: void QVector<Qt3DInput::QAxis*>::replace(int i, Qt3DInput::QAxis* const & t)

i must be a valid index position in the vector (i.e., 0 <= i < size()).
See also operator[]() and remove().
sourcepub fn reserve(&mut self, size: c_int)
pub fn reserve(&mut self, size: c_int)
C++ method: void QVector<Qt3DInput::QAxis*>::reserve(int size)
Attempts to allocate memory for at least size elements. If you know in advance how large the vector will be, you should call this function to prevent reallocations and memory fragmentation.
If size is an underestimate, the worst that will happen is that the QVector will be a bit slower. If size is an overestimate, you may have used more memory than the normal QVector growth strategy would have allocated—or you may have used less.
An alternative to reserve() is calling resize(). Whether or not that is faster than reserve() depends on the element type, because resize() default-constructs all elements, and requires assignment to existing entries rather than calling append(), which copy- or move-constructs. For simple types, like int
or double
, resize() is typically faster, but for anything more complex, you should prefer reserve().
Warning: If the size passed to resize() was underestimated, you run out of allocated space and into undefined behavior. This problem does not exist with reserve(), because it treats the size as just a hint.
sourcepub fn resize(&mut self, size: c_int)
pub fn resize(&mut self, size: c_int)
C++ method: void QVector<Qt3DInput::QAxis*>::resize(int size)
Sets the size of the vector to size. If size is greater than the current size, elements are added to the end; the new elements are initialized with a default-constructed value. If size is less than the current size, elements are removed from the end.
Since Qt 5.6, resize() doesn't shrink the capacity anymore. To shed excess capacity, use squeeze().
See also size().
sourcepub unsafe fn starts_with(&self, t: &*mut Axis) -> bool
pub unsafe fn starts_with(&self, t: &*mut Axis) -> bool
C++ method: bool QVector<Qt3DInput::QAxis*>::startsWith(Qt3DInput::QAxis* const & t) const
sourcepub fn swap(&mut self, other: &mut VectorAxisMutPtr)
pub fn swap(&mut self, other: &mut VectorAxisMutPtr)
C++ method: void QVector<Qt3DInput::QAxis*>::swap(QVector<Qt3DInput::QAxis*>& other)
Swaps vector other with this vector. This operation is very fast and never fails.
This function was introduced in Qt 4.8.
sourcepub fn take_at(&mut self, i: c_int) -> *mut Axis
pub fn take_at(&mut self, i: c_int) -> *mut Axis
C++ method: Qt3DInput::QAxis* QVector<Qt3DInput::QAxis*>::takeAt(int i)
Removes the element at index position i and returns it.
Equivalent to
T t = at(i); remove(i); return t;
Provided for compatibility with QList.
This function was introduced in Qt 5.2.
See also takeFirst(), takeLast(), and QList::takeAt().
sourcepub fn take_first(&mut self) -> *mut Axis
pub fn take_first(&mut self) -> *mut Axis
C++ method: Qt3DInput::QAxis* QVector<Qt3DInput::QAxis*>::takeFirst()
Removes the first item in the vector and returns it. This function assumes the vector is not empty. To avoid failure, call isEmpty() before calling this function.
This function was introduced in Qt 5.1.
See also takeLast() and removeFirst().
sourcepub fn take_last(&mut self) -> *mut Axis
pub fn take_last(&mut self) -> *mut Axis
C++ method: Qt3DInput::QAxis* QVector<Qt3DInput::QAxis*>::takeLast()
Removes the last item in the list and returns it. This function assumes the vector is not empty. To avoid failure, call isEmpty() before calling this function.
If you don't use the return value, removeLast() is more efficient.
This function was introduced in Qt 5.1.
See also takeFirst() and removeLast().
sourcepub fn value(&self, i: c_int) -> *mut Axis
pub fn value(&self, i: c_int) -> *mut Axis
C++ method: Qt3DInput::QAxis* QVector<Qt3DInput::QAxis*>::value(int i) const
Returns the value at index position i in the vector.
If the index i is out of bounds, the function returns a default-constructed value. If you are certain that i is within bounds, you can use at() instead, which is slightly faster.
See also at() and operator[]().
sourcepub unsafe fn value_unsafe(
&self,
i: c_int,
default_value: &*mut Axis
) -> *mut Axis
pub unsafe fn value_unsafe(
&self,

) -> *mut Axis
C++ method: Qt3DInput::QAxis* QVector<Qt3DInput::QAxis*>::value(int i, Qt3DInput::QAxis* const & defaultValue) const
This is an overloaded function.
If the index i is out of bounds, the function returns defaultValue.
