QCborArray Class

Member Function Documentation

QCborArray::QCborArray(std::initializer_list<QCborValue> args)

Initializes this QCborArray from the C++ brace-enclosed list found in args, as in the following example:

 QCborArray a = { null, 0, 1, 1.5, 2, "Hello", QByteArray("World") };

QCborArray::~QCborArray()

Destroys this QCborArray and frees any associated resources.

void QCborArray::append(const QCborValue &value)

Appends value into the array after all other elements it may already contain.

See also at(), operator[](), first(), last(), insert(), prepend(), removeAt(), and takeAt().

void QCborArray::append(QCborValue &&value)

Appends value into the array after all other elements it may already contain.

See also at(), operator[](), first(), last(), insert(), prepend(), removeAt(), and takeAt().

QCborValue QCborArray::at(qsizetype i) const

Returns the QCborValue element at position i in the array.

If the array is smaller than i elements, this function returns a QCborValue containing an undefined value. For that reason, it is not possible with this function to tell apart the situation where the array is not large enough from the case where the array starts with an undefined value.

See also operator[](), first(), last(), insert(), prepend(), append(), removeAt(), and takeAt().

iterator QCborArray::begin()

Returns an array iterator pointing to the first item in this array. If the array is empty, then this function returns the same as end().

See also constBegin() and end().

const_iterator QCborArray::begin() const

Returns an array iterator pointing to the first item in this array. If the array is empty, then this function returns the same as end().

See also constBegin() and constEnd().

const_iterator QCborArray::cbegin() const

Returns an array iterator pointing to the first item in this array. If the array is empty, then this function returns the same as end().

See also constBegin() and constEnd().

const_iterator QCborArray::cend() const

Returns an array iterator pointing to just after the last element in this array.

See also constBegin() and constEnd().

void QCborArray::clear()

const_iterator QCborArray::constBegin() const

Returns an array iterator pointing to the first item in this array. If the array is empty, then this function returns the same as end().

See also begin() and constEnd().

const_iterator QCborArray::constEnd() const

Returns an array iterator pointing to just after the last element in this array.

See also constBegin() and end().

bool QCborArray::contains(const QCborValue &value) const

Returns true if this array contains an element that is equal to value.

bool QCborArray::empty() const

Synonym for isEmpty(). This function is provided for compatibility with generic code that uses the Standard Library API.

Returns true if this array is empty (size() == 0).

See also isEmpty() and size().

iterator QCborArray::end()

Returns an array iterator pointing to just after the last element in this array.

See also begin() and constEnd().

const_iterator QCborArray::end() const

Returns an array iterator pointing to just after the last element in this array.

See also constBegin() and constEnd().

iterator QCborArray::erase(iterator it)

Removes the element pointed to by the array iterator it from this array, then returns an iterator to the next element (the one that took the same position in the array that it used to occupy).

See also insert(), removeAt(), takeAt(), takeFirst(), and takeLast().

iterator QCborArray::erase(const_iterator it)

Removes the element pointed to by the array iterator it from this array, then returns an iterator to the next element (the one that took the same position in the array that it used to occupy).

See also insert(), removeAt(), takeAt(), takeFirst(), and takeLast().

QCborValue QCborArray::extract(ConstIterator it)

Extracts a value from the array at the position indicated by iterator it and returns the value so extracted.

See also insert(), erase(), takeAt(), and removeAt().

QCborValue QCborArray::extract(Iterator it)

Extracts a value from the array at the position indicated by iterator it and returns the value so extracted.

See also insert(), erase(), takeAt(), and removeAt().

QCborValue QCborArray::first() const

Returns the first QCborValue of this array.

If the array is empty, this function returns a QCborValue containing an undefined value. For that reason, it is not possible with this function to tell apart the situation where the array is not large enough from the case where the array ends with an undefined value.

See also operator[](), at(), last(), insert(), prepend(), append(), removeAt(), and takeAt().

QCborValueRef QCborArray::first()

Returns a reference to the first QCborValue of this array. The array must not be empty.

QCborValueRef has the exact same API as QCborValue, with one important difference: if you assign new values to it, this array will be updated with that new value.

See also operator[](), at(), last(), insert(), prepend(), append(), removeAt(), and takeAt().

[static] QCborArray QCborArray::fromJsonArray(const QJsonArray &array)

Converts all JSON items found in the array array to CBOR using QCborValue::fromJson(), and returns the CBOR array composed of those elements.

This conversion is lossless, as the CBOR type system is a superset of JSON's. Moreover, the array returned by this function can be converted back to the original array by using toJsonArray().

See also toJsonArray(), toVariantList(), QCborValue::fromJsonValue(), and QCborMap::fromJsonObject().

[static] QCborArray QCborArray::fromStringList(const QStringList &list)

Returns a QCborArray containing all the strings found in the list list.

See also fromVariantList() and fromJsonArray().

[static] QCborArray QCborArray::fromVariantList(const QVariantList &list)

Converts all the items in the list to CBOR using QCborValue::fromVariant() and returns the array composed of those elements.

Conversion from QVariant is not completely lossless. Please see the documentation in QCborValue::fromVariant() for more information.

See also toVariantList(), fromStringList(), fromJsonArray(), and QCborMap::fromVariantMap().

void QCborArray::insert(qsizetype i, const QCborValue &value)

Inserts value into the array at position i in this array. If i is -1, the entry is appended to the array. Pads the array with invalid entries if i is greater than the prior size of the array.

See also at(), operator[](), first(), last(), prepend(), append(), removeAt(), takeAt(), and extract().

void QCborArray::insert(qsizetype i, QCborValue &&value)

Inserts value into the array at position i in this array. If i is -1, the entry is appended to the array. Pads the array with invalid entries if i is greater than the prior size of the array.

See also at(), operator[](), first(), last(), prepend(), append(), removeAt(), takeAt(), and extract().

iterator QCborArray::insert(iterator before, const QCborValue &value)

This is an overloaded function.

Inserts value into this array before element before and returns an array iterator pointing to the just-inserted element.

See also erase(), removeAt(), prepend(), and append().

iterator QCborArray::insert(const_iterator before, const QCborValue &value)

This is an overloaded function.

Inserts value into this array before element before and returns an array iterator pointing to the just-inserted element.

See also erase(), removeAt(), prepend(), and append().

See also size() and clear().

QCborValue QCborArray::last() const

Returns the last QCborValue of this array.

If the array is empty, this function returns a QCborValue containing an undefined value. For that reason, it is not possible with this function to tell apart the situation where the array is not large enough from the case where the array ends with an undefined value.

See also operator[](), at(), first(), insert(), prepend(), append(), removeAt(), and takeAt().

QCborValueRef QCborArray::last()
