Member Function Documentation

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().

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().

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

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

Prepends value into the array before any other elements it may already contain.

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

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().

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().

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(const QCborArray &other)

Copies the contents of other into this object.

QCborArray::QCborArray()

Constructs an empty QCborArray.

QCborArray &QCborArray::operator=(const QCborArray &other)

Replaces the contents of this array with that found in other, then returns a reference to this object.

QCborArray::~QCborArray()

Destroys this QCborArray and frees any associated resources.

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().

QCborArray::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().

QCborArray::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().

QCborArray::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().

QCborArray::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()

Empties this array.

See also isEmpty().

int QCborArray::compare(const QCborArray &other) const

Compares this array and other, comparing each element in sequence, and returns an integer that indicates whether this array should be sorted before (if the result is negative) or after other (if the result is positive). If this function returns 0, the two arrays are equal and contain the same elements.

For more information on CBOR sorting order, see QCborValue::compare().

See also QCborValue::compare(), QCborMap::compare(), and operator==().

QCborArray::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().

QCborArray::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.

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().

QCborArray::iterator QCborArray::end()

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

See also begin() and constEnd().

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

See also constBegin() and constEnd().

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)

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().

bool QCborArray::isEmpty() const

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()

Returns a reference to the last 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(), first(), insert(), prepend(), append(), removeAt(), and takeAt().

void QCborArray::pop_back()

See also takeAt(), removeLast(), removeFirst(), at(), operator[](), insert(), prepend(), and append().

QCborValue QCborArray::toCborValue() const

Explicitly construcuts a QCborValue object that represents this array. This function is usually not necessary since QCborValue has a constructor for QCborArray, so the conversion is implicit.

Converting QCborArray to QCborValue allows it to be used in any context where QCborValues can be used, including as items in QCborArrays and as keys and mapped types in QCborMap. Converting an array to QCborValue allows access to QCborValue::toCbor().

See also QCborValue::QCborValue(const QCborArray &).

QJsonArray QCborArray::toJsonArray() const

Recursively converts every QCborValue element in this array to JSON using QCborValue::toJsonValue() and returns the corresponding QJsonArray composed of those elements.

Please note that CBOR contains a richer and wider type set than JSON, so some information may be lost in this conversion. For more details on what conversions are applied, see QCborValue::toJsonValue().

See also fromJsonArray(), QCborValue::toJsonValue(), QCborMap::toJsonObject(), and toVariantList().

QVariantList QCborArray::toVariantList() const

Recursively converts each QCborValue in this array using QCborValue::toVariant() and returns the QVariantList composed of the converted items.

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

See also fromVariantList(), fromStringList(), toJsonArray(), QCborValue::toVariant(), and QCborMap::toVariantMap().

const QCborValue QCborArray::operator[](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 contains an undefined value at position i.

See also at(), first(), last(), insert(), prepend(), append(), removeAt(), and takeAt().

QCborValueRef QCborArray::operator[](qsizetype i)

Returns a reference to the QCborValue element at position i in the array. Indices beyond the end of the array will grow the array, filling with undefined entries, until it has an entry at the specified index.

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 at(), first(), last(), insert(), prepend(), append(), removeAt(), and takeAt().
