MEMBER FUNCTION DOCUMENTATION

 

QByteArray::QByteArray ()

Constructs an empty QByteArray.  

QByteArray::QByteArray ( int size )

Constructs a QByteArray of size size.  

RELATED FUNCTION DOCUMENTATION

 

QByteArray qCompress ( const QByteArray & data )

Compresses the array data and returns the compressed byte array using zlib.

See also qUncompress().

Compresses the array data which is nbytes long and returns the compressed byte array.  

QByteArray qUncompress ( const QByteArray & data )

Uncompresses the array data and returns the uncompressed byte array.

Returns an empty QByteArray if the input data was corrupt.

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.
