.SH DESCRIPTION
The QByteArray class provides an array of bytes.
.PP
The QByteArray class provides an explicitly shared array of bytes. It is useful for manipulating memory areas with custom data. QByteArray is implemented as a QMemArray<char>. See the QMemArray documentation for further information.
.PP
See also Collection Classes and Non-GUI Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QByteArray::QByteArray ()"
Constructs an empty QByteArray.
.SH "QByteArray::QByteArray ( int size )"
Constructs a QByteArray of size \fIsize\fR.
.SH RELATED FUNCTION DOCUMENTATION
.SH "QByteArray qCompress ( const QByteArray & data )"
Compresses the array \fIdata\fR and returns the compressed byte array.
.PP
See also qUncompress().
.SH "QByteArray qCompress ( const uchar * data, int nbytes )"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Compresses the array \fIdata\fR which is \fInbytes\fR long and returns the compressed byte array.
.SH "QByteArray qUncompress ( const QByteArray & data )"
Uncompresses the array \fIdata\fR and returns the uncompressed byte array.
.PP
Returns an empty QByteArray if the input data was corrupt.
.PP
See also qCompress().
.SH "QByteArray qUncompress ( const uchar * data, int nbytes )"
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
.PP
Uncompresses the array \fIdata\fR which is \fInbytes\fR long and returns
the uncompressed byte array.
