DESCRIPTION

29       The QByteArray class provides an array of bytes.
30
31       The QByteArray class provides an explicitly shared array of bytes. It
32       is useful for manipulating memory areas with custom data. QByteArray is
33       implemented as a QMemArray<char>. See the QMemArray documentation for
34       further information.

MEMBER FUNCTION DOCUMENTATION

QByteArray::QByteArray ()
40       Constructs an empty QByteArray.
41

QByteArray::QByteArray ( int size )
43       Constructs a QByteArray of size size.
44

QByteArray qCompress ( const QByteArray & data )
47       Compresses the array data and returns the compressed byte array using
48       zlib.
49
50       See also qUncompress().
51

QByteArray qCompress ( const uchar * data, int nbytes )
53       This is an overloaded member function, provided for convenience. It
54       behaves essentially like the above function.
55
56       Compresses the array data which is nbytes long and returns the
57       compressed byte array.
58

QByteArray qUncompress ( const QByteArray & data )
60       Uncompresses the array data and returns the uncompressed byte array.
61
62       Returns an empty QByteArray if the input data was corrupt.
63
64       See also qCompress().
65

QByteArray qUncompress ( const uchar * data, int nbytes )
67       This is an overloaded member function, provided for convenience. It
68       behaves essentially like the above function.
69
70       Uncompresses the array data which is nbytes long and returns the
71       uncompressed byte array.
