QByteArray(3qt)

📦 version 3.3.8b, in fedora 43, fedora 44

💖 QByteArray — the 3qt manual, but make it make sense 💖

okay bestie, gather round, because we're about to get intimate with an array of bytes. this is the QByteArray(3qt) page and honestly? it's short. it's sweet. it's giving "low-level but make it cute". let's go. ✨

🌸 NAME 🌸

QByteArray — Array of bytes. that's it. that's the whole name. no notes. 💅

✨ SYNOPSIS ✨

first thing first, the iconic disclaimer:

All the functions in this class are reentrant when Qt is built with thread support.</p>

(yes, the stray </p> is literally in the source. we don't fix it. we respect it. it's part of the lore. 🫶)

#include <qcstring.h>

Inherits QMemArray<char>.

Inherited by QBitArray and QCString. the family tree is thriving. 🌳

👑 Public Members

QByteArray ()
QByteArray ( int size )
QByteArray qCompress ( const QByteArray & data )
QByteArray qCompress ( const uchar * data, int nbytes )
QByteArray qUncompress ( const QByteArray & data )
QByteArray qUncompress ( const uchar * data, int nbytes )

squish and unsquish. the whole squad is here. 😌

💜 DESCRIPTION 💜

so. the QByteArray class provides an array of bytes. literally what it says on the tin, no cap.

more specifically? it's an explicitly shared array of bytes, and it's lowkey perfect for manipulating memory areas with custom data. the way it does this is by being implemented as a QMemArray<char> — so if you want the full tea, go read the QMemArray documentation, because that's where the real details live. 🍓

🎀 MEMBER FUNCTION DOCUMENTATION 🎀

QByteArray::QByteArray ()

Constructs an empty QByteArray. blank slate. main character at the start of her arc. 🌱

QByteArray::QByteArray ( int size )

Constructs a QByteArray of size size. that's the argument. that's the vibe. 📏

QByteArray qCompress ( const QByteArray & data )

Compresses the array data and hands you back the compressed byte array, using zlib. tiny data, big energy. 🔥

See also: qUncompress().

QByteArray qCompress ( const uchar * data, int nbytes )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Compresses the array data which is nbytes long and returns the compressed byte array. same energy, different entry point. ✨

QByteArray qUncompress ( const QByteArray & data )

Uncompresses the array data and returns the uncompressed byte array.

heads up bestie: it returns an empty QByteArray if the input data was corrupt. so if you get nothing back, that might be why. 😭

See also: qCompress().

QByteArray qUncompress ( const uchar * data, int nbytes )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

Uncompresses the array data which is nbytes long and returns the uncompressed byte array. 🦋

okay and that's the whole page!! it's from Trolltech AS, dated 2 February 2007, and it's the QByteArray(3qt) manual — version 3.3.8 of Qt, if you were wondering. love that for us. bye bestie, go compress something. 💖🎀🦋
