133 * This pair of functions is declared in qtools_p.h and is used by the Qt -

134 * containers to allocate memory and grow the memory block during append -

136 * -

137 * They take size_t parameters and return size_t so they will change sizes -

138 * according to the pointer width. However, knowing Qt containers store the -

139 * container size and element indexes in ints, these functions never return a -

140 * size larger than INT_MAX. This is done by casting the element count and -

141 * memory block size to int in several comparisons: the check for negative is -

142 * very fast on most platforms as the code only needs to check the sign bit. -

143 * -

144 * These functions return SIZE_MAX on overflow, which can be passed to malloc() -

145 * and will surely cause a NULL return (there's no way you can allocate a -

762 \class QByteArray -

763 \inmodule QtCore -

764 \brief The QByteArray class provides an array of bytes. -

765 -

766 \ingroup tools -

767 \ingroup shared -

768 \ingroup string-processing -

769 -

770 \reentrant -

771 -

772 QByteArray can be used to store both raw bytes (including '\\0's) -

773 and traditional 8-bit '\\0'-terminated strings. Using QByteArray -

774 is much more convenient than using \c{const char *}. Behind the -

775 scenes, it always ensures that the data is followed by a '\\0' -

776 terminator, and uses \l{implicit sharing} (copy-on-write) to -

777 reduce memory usage and avoid needless copying of data. -

778 -

779 In addition to QByteArray, Qt also provides the QString class to -

780 store string data. For most purposes, QString is the class you -

781 want to use. It stores 16-bit Unicode characters, making it easy -

782 to store non-ASCII/non-Latin-1 characters in your application. -

783 Furthermore, QString is used throughout in the Qt API. The two -

784 main cases where QByteArray is appropriate are when you need to -

785 store raw binary data, and when memory conservation is critical -

786 (e.g., with Qt for Embedded Linux). -

787 -

788 One way to initialize a QByteArray is simply to pass a \c{const -

789 char *} to its constructor. For example, the following code -

790 creates a byte array of size 5 containing the data "Hello": -

791 -

792 \snippet code/src_corelib_tools_qbytearray.cpp 0 -

793 -

794 Although the size() is 5, the byte array also maintains an extra -

795 '\\0' character at the end so that if a function is used that -

796 asks for a pointer to the underlying data (e.g. a call to -

797 data()), the data pointed to is guaranteed to be -

798 '\\0'-terminated. -

799 -

800 QByteArray makes a deep copy of the \c{const char *} data, so you -

801 can modify it later without experiencing side effects. (If for -

802 performance reasons you don't want to take a deep copy of the -

803 character data, use QByteArray::fromRawData() instead.) -

804 -

805 Another approach is to set the size of the array using resize() -

806 and to initialize the data byte per byte. QByteArray uses 0-based -

807 indexes, just like C++ arrays. To access the byte at a particular -

808 index position, you can use operator[](). On non-const byte -

809 arrays, operator[]() returns a reference to a byte that can be -

810 used on the left side of an assignment. For example: -

811 -

812 \snippet code/src_corelib_tools_qbytearray.cpp 1 -

813 -

814 For read-only access, an alternative syntax is to use at(): -

815 -

816 \snippet code/src_corelib_tools_qbytearray.cpp 2 -

817 -

818 at() can be faster than operator[](), because it never causes a -

819 \l{deep copy} to occur. -

820 -

821 To extract many bytes at a time, use left(), right(), or mid(). -

822 -

823 A QByteArray can embed '\\0' bytes. The size() function always -

824 returns the size of the whole array, including embedded '\\0' -

825 bytes, but excluding the terminating '\\0' added by QByteArray. -

826 For example: -

827 -

828 \snippet code/src_corelib_tools_qbytearray.cpp 48 -

829 -

830 If you want to obtain the length of the data up to and -

831 excluding the first '\\0' character, call qstrlen() on the byte -

832 array. -

833 -

834 After a call to resize(), newly allocated bytes have undefined -

835 values. To set all the bytes to a particular value, call fill(). -

836 -

837 To obtain a pointer to the actual character data, call data() or -

838 constData(). These functions return a pointer to the beginning of the data. -

839 The pointer is guaranteed to remain valid until a non-const function is -

840 called on the QByteArray. It is also guaranteed that the data ends with a -

841 '\\0' byte unless the QByteArray was created from a \l{fromRawData()}{raw -

842 data}. This '\\0' byte is automatically provided by QByteArray and is not -

843 counted in size(). -

844 -

845 QByteArray provides the following basic functions for modifying -

846 the byte data: append(), prepend(), insert(), replace(), and -

847 remove(). For example: -

848 -

849 \snippet code/src_corelib_tools_qbytearray.cpp 3 -

850 -

851 The replace() and remove() functions' first two arguments are the -

852 position from which to start erasing and the number of bytes that -

853 should be erased. -

854 -

855 When you append() data to a non-empty array, the array will be -

856 reallocated and the new data copied to it. You can avoid this -

857 behavior by calling reserve(), which preallocates a certain amount -

858 of memory. You can also call capacity() to find out how much -

859 memory QByteArray actually allocated. Data appended to an empty -

860 array is not copied. -

861 -

862 A frequent requirement is to remove whitespace characters from a -

863 byte array ('\\n', '\\t', ' ', etc.). If you want to remove -

864 whitespace from both ends of a QByteArray, use trimmed(). If you -

865 want to remove whitespace from both ends and replace multiple -

866 consecutive whitespaces with a single space character within the -

867 byte array, use simplified(). -

868 -

869 If you want to find all occurrences of a particular character or -

870 substring in a QByteArray, use indexOf() or lastIndexOf(). The -

871 former searches forward starting from a given index position, the -

872 latter searches backward. Both return the index position of the -

873 character or substring if they find it; otherwise, they return -1. -

874 For example, here's a typical loop that finds all occurrences of a -

875 particular substring: -

876 -

877 \snippet code/src_corelib_tools_qbytearray.cpp 4 -

878 -

879 If you simply want to check whether a QByteArray contains a -

880 particular character or substring, use contains(). If you want to -

881 find out how many times a particular character or substring -

882 occurs in the byte array, use count(). If you want to replace all -

883 occurrences of a particular value with another, use one of the -

884 two-parameter replace() overloads. -

885 -

886 \l{QByteArray}s can be compared using overloaded operators such as -

887 operator<(), operator<=(), operator==(), operator>=(), and so on. -

888 The comparison is based exclusively on the numeric values -

889 of the characters and is very fast, but is not what a human would -

890 expect. QString::localeAwareCompare() is a better choice for -

891 sorting user-interface strings. -

892 -

893 For historical reasons, QByteArray distinguishes between a null -

894 byte array and an empty byte array. A \e null byte array is a -

895 byte array that is initialized using QByteArray's default -

896 constructor or by passing (const char *)0 to the constructor. An -

897 \e empty byte array is any byte array with size 0. A null byte -

898 array is always empty, but an empty byte array isn't necessarily -

899 null: -

900 -

901 \snippet code/src_corelib_tools_qbytearray.cpp 5 -

902 -

903 All functions except isNull() treat null byte arrays the same as -

904 empty byte arrays. For example, data() returns a pointer to a -

905 '\\0' character for a null byte array (\e not a null pointer), -

906 and QByteArray() compares equal to QByteArray(""). We recommend -

907 that you always use isEmpty() and avoid isNull(). -

908 -

909 \section1 Notes on Locale -

910 -

911 \section2 Number-String Conversions -

912 -

913 Functions that perform conversions between numeric data types and -

914 strings are performed in the C locale, irrespective of the user's -

915 locale settings. Use QString to perform locale-aware conversions -

916 between numbers and strings. -

917 -

918 \section2 8-bit Character Comparisons -

919 -

920 In QByteArray, the notion of uppercase and lowercase and of which -

921 character is greater than or less than another character is -

922 locale dependent. This affects functions that support a case -

923 insensitive option or that compare or lowercase or uppercase -

924 their arguments. Case insensitive operations and comparisons will -

925 be accurate if both strings contain only ASCII characters. (If \c -

926 $LC_CTYPE is set, most Unix systems do "the right thing".) -

927 Functions that this affects include contains(), indexOf(), -

928 lastIndexOf(), operator<(), operator<=(), operator>(), -

929 operator>=(), toLower() and toUpper(). -

930 -

931 This issue does not apply to \l{QString}s since they represent -

932 characters using Unicode. -

933 -

936 -

937 /*! -

938 \enum QByteArray::Base64Option -

939 \since 5.2 -

940 -

941 This enum contains the options available for encoding and decoding Base64. -

942 Base64 is defined by \l{RFC 4648}, with the following options: -

943 -

944 \value Base64Encoding (default) The regular Base64 alphabet, called simply "base64" -

945 \value Base64UrlEncoding An alternate alphabet, called "base64url", which replaces two -

946 characters in the alphabet to be more friendly to URLs. -

947 \value KeepTrailingEquals (default) Keeps the trailing padding equal signs at the end -

948 of the encoded data, so the data is always a size multiple of -

949 four. -

950 \value OmitTrailingEquals Omits adding the padding equal signs at the end of the encoded -

951 data. -

952 -

953 QByteArray::fromBase64() ignores the KeepTrailingEquals and -

954 OmitTrailingEquals options and will not flag errors in case they are -

955 missing or if there are too many of them. -

1485 Note: QByteArray is an \l{implicitly shared} class. Consequently, -

1492 performed, taking \l{linear time}. -

1493 -

1494 This operation typically does not suffer from allocation overhead, -
