.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.

|
|
.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 using zlib.
|
|
.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.
